If you’ve ever stared at your Polychrome balance in Zenless Zone Zero wondering whether one more Signal Search is worth it, the honest answer is: guaranteeing a specific S-Rank Agent costs somewhere between $218 and $479, depending on your luck with the game’s 50/50 coin flip. That number isn’t a guess. It comes straight from HoYoverse’s own published pity mechanics and the official Monochrome pricing tiers sold through the App Store, Google Play, and Codashop.
This piece breaks down exactly how Zenless Zone Zero’s gacha odds work, shows the pity math step by step, and prices out what “guaranteed” actually costs in real dollars. No vibes, no rounded-off guesses – every rate below is cited from HoYoverse’s in-game disclosure or from third-party trackers that pull directly from it.
The short answer: what are Zenless Zone Zero’s gacha odds?
Zenless Zone Zero’s Signal Search system gives you a 0.6% base chance of pulling an S-Rank Agent or W-Engine on every single pull. That rate holds flat until roughly pull 74, at which point “soft pity” kicks in and your odds start climbing fast. By pull 90, the system forces a guaranteed S-Rank – this is “hard pity,” and it’s an absolute, no-exceptions ceiling. On a featured (limited) banner, getting an S-Rank doesn’t automatically mean you got the character you wanted. You then face a 50/50: half the time it’s the featured Agent, half the time it’s a random standard S-Rank. Lose that coin flip and your very next S-Rank pull on that banner is guaranteed to be the featured one.
Put together, the absolute worst-case scenario to guarantee a specific featured Agent is 180 pulls – two full 90-pull cycles, if you lose the 50/50 the first time. At 160 Polychrome per pull, that’s 28,800 Polychrome, which costs between $436 and $479 depending on which currency pack you buy. On average, though, most players land the featured Agent for roughly half that.
How Zenless Zone Zero’s pity system actually works
Zenless Zone Zero runs the same basic pity architecture as HoYoverse’s other titles (Genshin Impact, Honkai: Star Rail), but with its own specific numbers. Here’s the mechanic broken into its three moving parts.
Base rate and soft pity
Every Signal Search on the Exclusive Channel (the limited character banner) starts at a flat 0.6% chance of an S-Rank pull. That rate stays flat through pull 74. Community trackers such as GachaMath and PityCalculator, which log large volumes of pulls to reverse-engineer HoYoverse’s internal curve, consistently report that soft pity begins around pull 74–75 and climbs by roughly 6 percentage points per pull from there. HoYoverse doesn’t publish the exact shape of that ramp, so treat the slope as a community-tracked estimate, not an official figure – but the two hard anchor points (0.6% base, 100% at pull 90) are confirmed by the in-game probability disclosure panel.
Hard pity: the 90-pull guarantee
No matter how unlucky you get, pull 90 without an S-Rank forces one. This is the mechanic that makes gacha “provably fair” in the loose sense the industry uses that term – the system can’t withhold a drop indefinitely. It’s a hard mathematical ceiling, not a marketing claim.
The 50/50 and the guarantee that follows a loss
Getting an S-Rank on a limited banner doesn’t hand you the featured Agent outright. It’s a coin flip: 50% chance you get the featured unit, 50% chance you get a random standard S-Rank instead. If you lose, the system remembers – your next S-Rank pull on that banner is guaranteed to be the featured Agent. This design is why the worst-case cost is exactly double the single-cycle hard pity cost, not some unpredictable multiple.
Zenless Zone Zero pity table: probability by pull count
The table below shows your cumulative probability of hitting an S-Rank at specific pull counts. Pulls 1–74 use the officially confirmed flat 0.6% base rate. Pulls 75+ use the community-tracked soft-pity ramp, labeled clearly since HoYoverse hasn’t published exact per-pull figures for that stretch. Pull 90 is the confirmed 100% hard-pity guarantee.
| Pull Number | Per-Pull Rate | Cumulative Chance of S-Rank | Source |
|---|---|---|---|
| 1 | 0.6% | 0.6% | Official base rate |
| 25 | 0.6% | ~14.0% | Official base rate |
| 50 | 0.6% | ~26.0% | Official base rate |
| 74 | 0.6% | ~35.8% | Official base rate (last flat pull) |
| 75 | ~6.6% | ~40% | Community-tracked soft pity |
| 80 | ~36.6% | ~68% | Community-tracked soft pity |
| 85 | ~66.6% | ~91% | Community-tracked soft pity |
| 89 | ~90.6% | ~99% | Community-tracked soft pity |
| 90 | 100% | 100% | Official hard pity |
Two things stand out here. First, the base rate alone gets you to roughly a coin-flip’s chance of an S-Rank by pull 74, before soft pity even engages. Second, once soft pity kicks in at pull 75, odds climb steeply enough that most players see their S-Rank land somewhere in the mid-to-high 70s or low 80s, not right at the pull-90 wall.
The pity-cost table: what “guaranteed” actually costs
This is the number that actually matters when you’re deciding whether to top up. Polychrome costs 160 per pull. Monochrome, the currency you buy with real money, converts to Polychrome at a flat 1:1 rate. HoYoverse sells Monochrome in six official tiers, and – this surprised us – the biggest pack isn’t the best value. The $29.99 tier (1,980 Monochrome) actually gives a slightly better per-dollar rate than the $99.99 tier, because of how each tier’s pricing is structured.
| Scenario | Pulls Needed | Polychrome Cost | Best-Rate USD ($29.99 tier) | Worst-Rate USD ($4.99 tier) |
|---|---|---|---|---|
| Average pulls to first S-Rank (conservative, ignoring soft-pity boost) | ~70 pulls | 11,200 | $169.64 | $186.29 |
| Guaranteed ANY S-Rank (hard pity, one cycle) | 90 pulls | 14,400 | $218.11 | $239.52 |
| Average pulls to guarantee the FEATURED Agent (accounts for 50/50) | ~105 pulls | 16,800 | $254.46 | $279.44 |
| Worst case: guaranteed FEATURED Agent (lose 50/50, then hit second hard pity) | 180 pulls | 28,800 | $436.22 | $479.04 |
The “average pulls to first S-Rank” row is deliberately conservative: it’s calculated using only the flat 0.6% base rate, capped at the 90-pull hard pity, with zero credit given for the soft-pity ramp that HoYoverse doesn’t publish exact numbers for. That means roughly 70 pulls is closer to a ceiling on the true average than a floor – in practice, soft pity likely pulls the real average down somewhat below that. We’d rather understate your odds than overstate them.
Step-by-step: how the expected value math works
Here’s exactly how the “~105 pulls” average-to-featured-Agent figure was calculated, so you can check the work or apply it to your own pity count.
- Step 1 – Model the capped geometric distribution. With a flat 0.6% chance per pull and a hard cap at 90, the expected number of pulls to your first S-Rank is E[N] = (1 − (1 − p)^90) / p, where p = 0.006. Plugging in the numbers: (1 − 0.9939^90) / 0.006 ≈ 69.7 pulls.
- Step 2 – Account for the 50/50. Half the time, that first S-Rank is already the featured Agent, done in ~70 pulls. The other half, a second S-Rank is needed, now guaranteed to be the featured one, but it still takes up to another 90-pull cycle to reach (averaging that same ~69.7 pulls).
- Step 3 – Weight the two outcomes. Expected total pulls = 69.7 + (0.5 × 69.7) = 104.5, rounded to 105 pulls.
- Step 4 – Convert to currency. 105 pulls × 160 Polychrome = 16,800 Polychrome.
- Step 5 – Convert to dollars. At the best available rate ($29.99 for 1,980 Monochrome, or $0.01515 per Polychrome), 16,800 Polychrome costs $254.46. At the worst rate ($4.99 for 300 Monochrome, or $0.01663 per Polychrome), it costs $279.44.
That’s the whole calculation. No hidden multipliers, no “whale tax” – the entire cost curve is just pull count times 160 Polychrome, converted at whatever exchange rate a given Monochrome purchase gives.
Worked examples: five real spending scenarios
Numbers in the abstract don’t mean much until they’re applied. Here are five concrete scenarios using the confirmed rates above.
Example 1: The lucky F2P player
You’ve saved 8,000 Polychrome from events and daily missions – 50 pulls. Your cumulative chance of hitting an S-Rank by pull 50 is roughly 26%, using the flat base rate alone (soft pity hasn’t started yet at pull 50). That’s a little worse than 1-in-4 odds. If you don’t hit by pull 50, nothing extra is lost – pity carries forward, so every pull made later still counts toward the same 90-pull ceiling.
Example 2: Pulling to soft pity and stopping
You commit to pulling until pull 80 and then stop regardless. At pull 80, cumulative odds (base rate through 74, community-tracked ramp from 75–80) sit at roughly 68%. That means close to a third of players following this strategy walk away with nothing at pull 80, having spent 12,800 Polychrome (roughly $194–$213 depending on pack tier) with no S-Rank at all – a real risk worth planning for.
Example 3: Budgeting for the featured character with a single purchase
You want to guarantee the featured Agent with a single top-up, no gambling on soft pity. That means budgeting for the full 180-pull worst case: 28,800 Polychrome. At the best available rate ($29.99 per 1,980 Monochrome), roughly 14.5 purchases of that tier are needed, totaling $436.22. Buying the single largest $99.99 tier repeatedly instead costs $444.40 for the same 28,800 Polychrome – about $8 more, purely because the biggest pack isn’t quite the best per-dollar rate.
Example 4: The “double 50/50 loss” nightmare scenario
This is technically outside the guaranteed system: because the loss-guarantee only applies to the very next S-Rank, the 50/50 cannot be lost twice in a row on the same banner cycle by design. The worst mathematically possible outcome remains capped at 180 pulls (28,800 Polychrome, up to $479.04). Any story about someone needing 250-plus pulls for one character is either describing a different game’s system or multiple separate banner cycles for different characters, not one guaranteed pull.
Example 5: Comparing to a single $99.99 purchase
A single $99.99 purchase gets 6,480 Polychrome – 40 pulls. Using the flat base-rate-only model, cumulative chance of an S-Rank within those 40 pulls is about 21.6%. That’s roughly 1-in-5 odds for a $100 spend, well short of a coin flip, since soft pity hasn’t engaged yet at pull 40.
Myths vs. facts about Zenless Zone Zero’s gacha system
Gacha communities pass around a lot of half-true claims. Here’s what’s confirmed versus what’s exaggerated.
| Claim | Myth or Fact | Explanation |
|---|---|---|
| “Pity resets to zero if you switch banners.” | Myth (mostly) | The S-Rank pity counter is shared across relevant Exclusive Channel banners in ZZZ – it does not reset just because a new featured Agent rotates in. |
| “You can lose the 50/50 multiple times in a row for the same character.” | Myth | The guarantee-after-loss mechanic locks the very next S-Rank on that banner to the featured unit – the coin flip cannot be lost twice consecutively within one pity cycle. |
| “The base rate is 0.6% no matter what.” | Fact, with a caveat | 0.6% is the confirmed flat rate through pull 74. From pull 75 onward, soft pity raises the effective rate well above 0.6%, up to the guaranteed 100% at pull 90. |
| “A-Rank characters are guaranteed every 10 pulls.” | Fact | Confirmed by HoYoverse’s in-game disclosure and mirrored across independent trackers. |
| “Buying the biggest currency pack always gives the best value.” | Myth | The $29.99 (1,980 Monochrome) tier beats the $99.99 (6,480 Monochrome) tier on a per-dollar basis in the official US pricing table. |
| “HoYoverse never discloses drop rates.” | Myth | The base rate, soft-pity start point, hard-pity cap, and 50/50 mechanic are all disclosed in-client via the banner’s probability details panel, consistent with transparency requirements in several regulated markets. |
How Zenless Zone Zero compares to other gacha pity systems
ZZZ’s numbers sit in a fairly standard band for HoYoverse-style gacha, but they’re not identical to competitors. Wuthering Waves, for comparison, runs a slightly more generous base rate of 0.8% with an 80-pull hard pity and soft pity beginning around pull 66, using the same 160-currency-per-pull cost and the same 50/50-with-guarantee structure, according to reporting from GameRant and Charlie INTEL. That means WuWa’s hard-pity ceiling for a featured Resonator (160 pulls worst case) is cheaper in raw pull count than ZZZ’s 180-pull ceiling, even though the per-pull currency cost is comparable.
The takeaway for ZZZ players: a lower base rate (0.6% versus 0.8%) is partly offset by a longer runway to hard pity (90 versus 80), so the two systems land in a broadly similar place for total expected spend, even though the individual numbers don’t match one another.
Is Zenless Zone Zero’s gacha system “fair”?
“Fair” is doing a lot of work in that question, so it’s worth separating two claims. The mechanics are transparent and mathematically bounded: HoYoverse publishes the base rate, the hard pity cap, and the guarantee-after-loss rule inside the client, and every pull is independently verifiable against those published numbers by trackers like PityCalculator and GachaMath. In that narrow sense, yes – the system does what it says it does, and there’s no hidden mechanic silently reducing odds below the stated rate.
Whether it’s fair in the sense of “reasonably priced” is a separate question, and the answer depends on budget. A worst-case $436–$479 spend to guarantee one specific character is a real cost, not a marketing abstraction, and it sits above what most single-player or subscription games charge for an entire title. Whether that’s worth it comes down to how much a specific Agent is valued and how much variance is tolerable – half of players get there for roughly $254–$279 on average, and some get lucky enough to hit it inside their first 20–30 pulls for a fraction of that.
Practical tips before committing Polychrome
- Track your pity counter using the in-client detail panel or a third-party tracker – most calculators (like PityCalculator’s ZZZ tool) accept a current pity input for a personalized probability instead of the general averages above.
- If topping up specifically to guarantee a character, budget for the 180-pull worst case (28,800 Polychrome), not the average case – hoping for average luck and running out of currency mid-banner is the most common regret players report.
- Compare per-dollar Polychrome rates before buying. The $29.99 tier consistently beats the $99.99 tier on a per-unit basis in the US pricing table, so splitting a large purchase into multiple mid-tier buys can save a few dollars.
- Remember the A-Rank guarantee (one every 10 pulls) has real value even on a “failed” pull toward an S-Rank goal – nothing is wasted even when the S-Rank doesn’t land.
- If a banner is about to rotate deep into a soft-pity run without an S-Rank, it’s generally safer to finish that pull-to-90 cycle before the banner changes, since the confirmed pity carryover applies to the S-Rank counter, not necessarily to a specific featured character’s rate-up window.
Frequently asked questions
What is the S-Rank pity cap in Zenless Zone Zero?
Hard pity is 90 pulls (Signal Searches) on the Exclusive Channel. If an S-Rank hasn’t landed by then, the 90th pull is guaranteed to be one, at a cost of 14,400 Polychrome.
How much does it cost to guarantee the featured character in Zenless Zone Zero?
Worst case, 180 pulls (28,800 Polychrome), running $436.22 to $479.04 in real money depending on which Monochrome pack tier is used. On average, accounting for the 50/50 mechanic, it’s closer to 105 pulls (16,800 Polychrome, roughly $254–$279).
Does Zenless Zone Zero have a 50/50 system like Genshin Impact?
Yes. Getting an S-Rank on a limited banner gives a 50% chance it’s the featured Agent. Lose that flip and the next S-Rank on that banner is guaranteed to be the featured one – the coin flip can’t be lost twice in a row for the same pity cycle.
What’s the base drop rate for S-Rank Agents in Zenless Zone Zero?
0.6% per pull, flat, through roughly pull 74. From pull 75 onward, soft pity increases the effective odds until the guaranteed 100% at pull 90.
Is it better to buy the $99.99 Monochrome pack or smaller packs?
Neither the biggest nor the smallest pack wins outright. The $29.99 tier (1,980 Monochrome) gives the best per-dollar rate in the official US pricing table, narrowly beating the $99.99 tier. The $4.99 tier (300 Monochrome) is the worst per-dollar value.
Can pity carry over between different banners in Zenless Zone Zero?
The S-Rank pity counter is shared across the relevant limited Exclusive Channel banners rather than resetting each time a new featured Agent rotates in, based on current tracker and community-guide documentation.
