Getting a 6-star unit in All Star Tower Defense is the single biggest power spike you can chase, but blowing your gem stash on the wrong banner will set you back weeks. The key to all star tower defense how to get 6 star success isn't luck alone — it's knowing when to save, which banners to pull, and how to stretch every free gem. This guide breaks down the exact strategy that free-to-play players use to land top-tier units without spending a dime.
The 6-star tier sits above the standard 5-star pool, and these units often carry entirely different abilities, higher stat multipliers, and better upgrade paths. While the base game on Roblox rotates featured units every hour, the real question is how you allocate your resources across days or weeks. If you've been pulling on every banner that looks shiny, you're probably wasting gems that could have guaranteed you a 6-star on a rate-up banner instead.
Understanding the 6-Star Summon Pool and Drop Rates
Before you spend a single gem, you need to understand how the summon gate actually works in ASTD. The game separates units into star tiers, and 6-star units occupy the top of the standard summon pool — though they're not the absolute rarest (that honor belongs to 7-star and mystical units). What makes 6-star units special is that they're the highest tier you can reasonably target as a free-to-play player without relying on extreme luck or trading.
The summon gate offers several banner types, and each one has different odds, which is critical to understand if you're chasing a 6-star unit. Based on community data and player reports from the ASTD Discord, the current rates break down roughly like this: the standard banner sits at a mere 0.5% for a 6-star, while limited-time banners often boost that to 1% or even 2% during special events. However, don't ignore the pity system—every 100 summons on a featured banner guarantees a 6-star, which is why saving your gems for a high-rate banner (like a 2x event) is far more efficient than pulling on the standard pool. For F2P players, this means hoarding gems for these windows is the single best strategy to maximize your odds without spending a dime.
| Banner Type | 6-Star Rate | 5-Star Rate | 4-Star Rate | Cost per Pull |
|---|---|---|---|---|
| Standard Gate | 1-2% | 8-10% | 30-35% | 100 Gems |
| Stardust Banner | 3-5% | 15-20% | 40% | 50 Stardust |
| Featured/Event Banner | 2-4% | 12-15% | 35% | 100 Gems |
| Limited-Time Banner | 5-8% | 20-25% | 45% | 150 Gems |
These numbers are approximate and shift with each update, but the pattern holds: limited-time banners offer the best 6-star odds while standard pulls give you the worst value per gem. That's why the community consensus is clear — never pull on the standard gate if you're hunting for 6-star units specifically.
Why 6-Star Units Matter More Than Raw DPS
A 6-star unit isn't just a stat stick. These units typically come with unique passives, extra ability slots, or transformation mechanics that 5-star units simply don't have access to. For example, some 6-star units can hit multiple enemy types simultaneously, while others generate extra cash per kill — abilities that fundamentally change how you approach wave defense.
When you're working through harder story stages or the Infinity Tower, these extra mechanics often matter more than raw damage numbers. A well-positioned 6-star unit with the right trait can carry a team that would otherwise struggle with late-game enemy spam. That's why all star tower defense save gems advice exists — you want to have enough saved when the right banner appears.
How to Save Gems Efficiently for 6-Star Banners
The biggest mistake new players make is treating gems like they're worthless. Every 100 gems you spend on a random banner pull is 100 gems you can't use when a guaranteed 6-star banner drops. The all star tower defense f2p summon guide approach is simple: set a savings goal and don't touch your stash until you hit it.
Here's a realistic savings roadmap based on how much you play: if you’re a casual player logging in just for dailies and weekly missions, you’ll bank roughly 1,500–2,000 gems per week, meaning a 3,000-gem 6-star banner pull takes about two weeks of steady saving. For semi-active players who grind story mode on hard difficulty and clear all limited-time event tasks, that jumps to 3,500–4,500 gems weekly, letting you summon every other banner. Hardcore grinders who farm raid stages and sell duplicate units can hit 6,000+ gems weekly, ensuring they never miss a meta-defining 6-star like a new time-stop unit. The key is to set a hard rule: never spend below your target threshold, because a single impulse 5-star summon can set you back an entire day of grinding, and that’s exactly how f2p players lose their chance at the next top-tier unit.
-
Casual players (1-2 hours/day): Aim for 3,000-5,000 gems saved before pulling. This gives you 30-50 pulls on a featured banner, which is enough to hit the 6-star rate at least once statistically.
-
Regular players (3-4 hours/day): Target 8,000-10,000 gems. At this level, you can afford to pull on every limited-time banner that features a 6-star unit you actually want.
-
Hardcore grinders (5+ hours/day): Save 15,000+ gems. You're playing enough that you can afford to chase specific units across multiple banner rotations.
The math is straightforward: if a limited banner has a 5% 6-star rate, you need roughly 20 pulls for a 50% chance of seeing one. Thirty pulls gets you to about 78%, and 50 pulls pushes you past 92%. Saving 5,000 gems gives you a statistically strong shot at landing at least one 6-star unit on a decent banner.
Daily and Weekly Gem Income Sources
To hit those savings targets, you need a steady income stream. The game gives you gems through multiple channels—daily login streaks, weekly raid rewards, and quest milestones—and stacking them all together makes saving much faster. For example, a player who completes every daily mission, claims the weekly tournament payout, and opens the free gem chest every four hours can bank roughly 300–400 gems per week without spending a cent. That consistent flow is what lets you reach the 1,500-gem threshold for a guaranteed 6-star summon in just over a month, instead of relying on luck alone.
| Income Source | Gems per Day | Notes |
|---|---|---|
| Daily Login Bonus | 50-150 | Increases with consecutive days |
| Story Mode First Clears | 200-500 | One-time per stage, but adds up |
| Weekly Challenges | 300-600 | Resets every Monday |
| Infinite Tower Milestones | 100-300 | Every 10 floors |
| Code Redemptions | Varies | Check for active codes regularly |
The tboicats code alone gives you 3,000 gems plus 170 stardust, which is a massive head start. Other active codes like sorryfordelayandmonkeyking (4,000 gems + 280 stardust) and superdaydaykid100ksubs (9,000 gems + 220 stardust) are even better. Always check Pocket Tactics' ASTD codes page before summoning — those free gems often make the difference between hitting your savings goal and falling short.
Best Banners to Target for 6-Star Units
Not all 6-star banners are created equal. The current rotation in 2026 features several banner types, and knowing which ones to prioritize is the core of all star tower defense summon all units strategy. You want to maximize your odds while minimizing gem waste.
The Stardust Banner is arguably the best value in the game right now. It costs 50 stardust per pull instead of gems, and the 6-star rate is noticeably higher than the standard gate. Stardust drops from story mode stages, event rewards, and code redemptions — the ultramicro code gives you 100 stardust, and game11 gives you another 100 plus 300 gems.
For players aiming to secure a 6-star unit, understanding the current summoning rates is crucial—check out the Astd Stardust Banner to see which featured units can boost your chances.
Comparing Banner Value in the Current Meta
Here's how the current banner rotation stacks up for 6-star hunting: limited-time banners (like the recent Hero Fest) offer boosted rates for featured meta units, but they rotate out quickly, forcing you to either spend gems immediately or wait months for a rerun. In contrast, the standard banner always contains the full 6-star pool, making it the most reliable—though slower—option for f2p players. If you're saving gems for a specific unit, check the banner's pity counter first; otherwise, dumping all your gems into a limited banner without a guarantee can leave you empty-handed when the rotation shifts.
| Banner | 6-Star Odds | Cost | Value Rating | Best For |
|---|---|---|---|---|
| Stardust Banner | 3-5% | 50 Stardust | ★★★★★ | F2P players with stardust reserves |
| Limited-Time Featured | 5-8% | 150 Gems | ★★★★☆ | Players with 5,000+ saved gems |
| Standard Gate | 1-2% | 100 Gems | ★★☆☆☆ | New players learning the game |
| Event Banners | 2-4% | 100 Gems | ★★★☆☆ | Collectors wanting event exclusives |
The Stardust Banner wins because it doesn't touch your gem reserves at all. You can farm stardust through story mode while your gems sit untouched, waiting for a limited-time banner that features a 6-star unit you actually want. This dual-currency approach is how serious F2P players maintain two separate summoning budgets.
The Free-to-Play Summoning Strategy That Works
The all star tower defense f2p summon guide boils down to one principle: never pull on impulse. Every gem you spend should be part of a deliberate plan, because a single wasted 150-gem summon on the standard banner can set you back an entire week of daily quests and raid rewards—especially when you're grinding toward that elusive 6-star unit. Here's the exact strategy that community veterans recommend: save every free gem until a limited-time banner with a guaranteed 6-star pity counter appears, then dump your entire stash in one focused session. This approach maximizes your odds of hitting the 6-star drop rate (roughly 1% base, boosted by pity) while avoiding the trap of spreading resources thin across multiple banners.
Step 1: Build your gem reserve to 5,000 minimum. Use codes, story mode clears, and daily bonuses to hit this number before you even think about summoning. The sbrupdate code alone gives you 9,000 gems plus 240 stardust, which instantly puts you in a strong position.
Step 2: Identify which 6-star units you actually need. Look at your current team composition. Are you missing a boss killer? A crowd control unit? A cash generator? Target banners that feature those specific roles rather than pulling on everything.
Step 3: Wait for limited-time banners with 5%+ 6-star rates. These appear roughly every 2-3 weeks based on the update schedule. When one drops, spend your saved gems in batches of 10 pulls rather than single pulls — some players report better results with multi-pulls, though the game doesn't officially confirm this.
How to Summon All Units Without Breaking Your Bank
The phrase all star tower defense summon all units sounds impossible for F2P players, but it's actually achievable with patience. The key is understanding that you don't need every unit — you need the right units for your playstyle. Focus on collecting 6-star units that fill specific roles, and skip banners that don't offer anything your team is missing.
A balanced 6-star collection looks something like this: one dedicated DPS unit (e.g., a maxed-out 6-star Ichigo or Kaido), one support buffer (like a 6-star Bulma or Whitebeard for damage boosts), one crowd-control specialist (think 6-star Law or Luffy for stuns), and one tanky frontline unit (such as a 6-star Broly or Aizen) to absorb hits. This spread ensures you cover all game modes—from raid bosses to wave defense—without overspending gems on duplicates. For f2p players, prioritize summoning on banners featuring these archetypes over chasing every new unit, as a single well-rounded 6-star team can clear most endgame content, saving your hard-earned gems for limited-time events.
-
1-2 boss killers for story mode and raid content
-
2-3 crowd control units for wave-heavy stages
-
1-2 cash generators to fuel your economy
-
1-2 support units with buffs or debuffs
-
1 flex slot for whatever the current meta favors
This approach lets you skip most banners entirely, saving your gems for the ones that matter. When you see a limited-time banner featuring a 6-star boss killer and you already have two, skip it. Wait for the crowd control banner instead.
Advanced Tips for Maximizing Your 6-Star Pulls
Once you've mastered the basics of saving and targeting banners, a few advanced tricks can push your success rate even higher. These aren't guaranteed methods — the game uses RNG, and no strategy can guarantee a 6-star pull — but they improve your odds and reduce waste.
Trait synergy matters more than raw stats. A 6-star unit with a mediocre trait is often worse than a 5-star unit with a perfect trait. Before you celebrate a 6-star pull, check its trait. If it's a bad one, you might need to use the trait reroll system, which costs stardust. Factor this into your resource planning.
Save stardust for trait rerolls, not just summons. The Stardust Banner is tempting, but if you pull a 6-star unit with a terrible trait, you'll need stardust to fix it. Keep a reserve of 200-300 stardust specifically for rerolls before you start spending on the stardust banner.
When to Stop Pulling
Knowing when to stop is just as important as knowing when to start, especially when your gem count is the only thing standing between you and a 6-star unit. If you’ve already pulled 30–40 times without a single featured unit, the odds of hitting the jackpot on the next single pull are still brutally low—and burning your last 500 gems on a desperate roll will only delay your next guaranteed 6-star banner. A good rule of thumb: stop once you’ve spent 50% of your saved gems, or as soon as you’ve secured one copy of the current meta unit. That way, you’ll always have a reserve for the next limited-time event, and you won’t end up with an empty wallet and a bench full of 4-star duplicates. Here's a quick decision guide:
| Situation | Recommended Action |
|---|---|
| Pulled a 6-star in first 10 pulls | Stop, save the rest for the next banner |
| 30 pulls with no 6-star | Keep going if rate is 5%+, stop if it's lower |
| Hit your savings floor (2,000 gems left) | Stop immediately, rebuild your reserve |
| Banner has less than 24 hours left | Skip it, wait for the next rotation |
Discipline is the real secret to all star tower defense how to get 6 star success. The players who land multiple 6-star units aren't luckier than you — they're just better at saving and more selective about when they pull. According to community reports from the ASTD subreddit, most successful F2P collectors spend 70% of their time saving and only 30% actually summoning.
Gem-Wasting Habits That Block 6 Stars
Even experienced players fall into traps that drain their gem reserves, and the most common culprit is panic-summoning on the standard banner instead of waiting for the limited-time 6-star rate-up events. For example, spending 500 gems on a regular 10-pull when a boosted banner for a meta unit like a 6-star Goku or Luffy is just days away can set you back weeks of F2P grinding. The community also reports wasting gems on revives or refresh timers during early stages, which are rarely worth it when you can simply replay a lower wave to rebuild your team. To avoid this, always check the in-game news tab and save your gems for guaranteed 6-star summons, as the drop rate difference is staggering—often 2x or more compared to the standard pool.
Pulling on the standard gate is the #1 gem waster. At 1-2% 6-star odds, you'd need 50-100 pulls on average to see one 6-star unit. That's 5,000-10,000 gems for a single 6-star — terrible value compared to limited banners.
Chasing every new banner is the #2 mistake. Just because a new unit drops doesn't mean you need it. The game introduces new units regularly, and most of them are sidegrades rather than upgrades. Wait for units that genuinely improve your team.
Ignoring code redemptions is the #3 mistake. The yickadee code gives you 2,000 gems plus 230 stardust and a limited unit at Lv100+. Codes like this are free resources that many players skip, which is crazy when you're trying to save gems.
Planning Pulls Around Your Gem Income
The best way to avoid these mistakes is to build a routine that keeps your gem income higher than your spending. Here's a sustainable cycle that works: after every daily mission reset, bank your gems from quests and the weekly tournament before touching the summon banner. Then, set a hard rule—only summon when you've stacked at least 500 gems above your savings floor, and never pull more than three times in a row. This discipline ensures you always have a reserve for the next 6-star rate-up banner, turning a frustrating RNG grind into a steady, f2p-friendly path toward that elusive all star tower defense 6 star unit.
-
Week 1-2: Farm story mode, complete daily challenges, redeem all active codes. Save every gem.
-
Week 3: Check if a limited-time 6-star banner is active. If yes, spend up to half your saved gems. If no, keep saving.
-
Week 4: Rebuild your reserve. Use stardust for any trait rerolls you need.
-
Repeat: Over 2-3 months, this cycle should land you 2-4 solid 6-star units.
This approach works because it treats gems as a long-term investment rather than a disposable currency. The players who consistently have strong teams aren't the ones who pull the most — they're the ones who pull smart. By sticking to a strict 500-gem daily cap and only summoning during rate-up banners for meta units like Goku Black or Drip Ichigo, you guarantee that every 10-pull moves you closer to a 6-star evolution. Meanwhile, hoarding a 3,000-gem emergency reserve lets you capitalize on surprise limited events without breaking your f2p budget, turning patience into your strongest summoning advantage.
Frequently Asked Questions
What's the fastest way to get a 6-star unit in All Star Tower Defense?
The fastest reliable method is saving 5,000+ gems and waiting for a limited-time banner with 5%+ 6-star rates. Redeem active codes like tboicats and sbrupdate for free gems, then spend them in 10-pull batches on featured banners. This gives you the best statistical chance without relying on pure luck.
Should I spend gems on the standard summon gate?
No. The standard gate has the worst 6-star odds at 1-2%, making it the worst gem investment in the game. Save your gems for limited-time banners or use stardust on the Stardust Banner instead. Standard pulls are only worth it for new players who need basic units to progress through early story stages.
How many gems should I save before summoning?
Aim for at least 5,000 gems before you start pulling on 6-star banners. This gives you 50 pulls, which translates to roughly a 92% chance of landing a 6-star on a 5% rate banner. If you're targeting a specific unit, save 8,000-10,000 gems to ensure you can pull until you get it.
Can I get 6-star units without spending real money?
Yes, completely free-to-play. The all star tower defense f2p summon guide relies on daily login bonuses, story mode clears, weekly challenges, and code redemptions. Active codes like superdaydaykid100ksubs and sorryfordelayandmonkeyking provide thousands of free gems, making 6-star units very achievable for F2P players.
What should I do if I pull a 6-star unit with a bad trait?
Save 200–300 stardust before rolling traits on a 6-star. A bad trait tanks DPS or range, so rerolling beats wasting pulls. Check the ASTD tier list for meta traits per unit—like Boss Slayer on damage dealers. Then lock in your target and grind that banner.
