A free-to-play Zenless Zone Zero account can comfortably guarantee one featured S-Rank Agent per patch and still keep a small cushion. That is the number that matters, and everything below explains how to hit it without spending a cent, where your income hides, and how to avoid the two mistakes that drain accounts fastest.
The currencies, in plain terms
ZZZ hides its pull economy behind three names, and the pity system tracks each banner separately.
- Polychrome is the premium currency you accumulate. It does nothing on its own. You convert it into pull tickets at a rate of 160 Polychrome per pull.
- Master Tapes pull on the permanent Star-Studded Cast (standard) banner. Encrypted Master Tapes pull on the limited Agent banner, the Exclusive Channel where new S-Ranks debut.
- Boopons pull on the W-Engine Channel, the weapon banner tied to the current featured Agent.
You can buy tapes and Boopons with Polychrome one at a time, or roll straight from a Polychrome balance. The bookkeeping is the same. When people say "I have 90 pulls saved," they mean roughly 14,400 Polychrome sitting in the bank.
How pity actually works
The pity ceiling is where new players get the math wrong, so here it is cleanly.
Agent banner (Exclusive Channel):
- Guaranteed S-Rank Agent within 90 pulls. The soft pity that raises your odds kicks in in the mid-70s, so most S-Ranks arrive a little before the hard ceiling.
- When an S-Rank drops, it is a 50/50: half the time it is the featured Agent, half the time it is a random standard S-Rank.
- Lose the 50/50, and your next S-Rank is a guaranteed featured Agent. So the true worst case for a specific Agent is 180 pulls, and the average is closer to 100 to 110.
- A-Rank pity sits at 10, with a guaranteed featured A-Rank on that track.
W-Engine banner (W-Engine Channel):
- Guaranteed S-Rank W-Engine within 80 pulls.
- The featured-item chance is 75/25, not 50/50, and it resolves in one pull rather than needing a "lose then win" cycle. That makes weapons cheaper in expectation than characters, but the banner is separate income, so it still competes for your Boopons.
The single most useful habit: know your current pity count before every banner. The game shows it. An account 70 pulls into the Agent banner is in a completely different decision than one at zero.
Where your income comes from
Free income in ZZZ is spread across a dozen small taps. Individually they look trivial. Added up over a full patch, they are the whole game. The reliable sources, roughly in order of size:
- Version event rewards. The main event chain each patch is the single largest Polychrome payout, usually enough for a big chunk of a 10-pull stack.
- Endgame modes. Shiyu Defense and Deadly Assault refresh on a cycle and pay Polychrome scaled to how many stars you clear. Clearing the top rows is the biggest recurring skill-based income you control.
- Hollow Zero and Ridu Weekly. Hollow Zero hands out a weekly Polychrome cap plus investigation currency. The Ridu Weekly bounties are quick and worth doing.
- Trust and dailies. Daily engagement points and commissions trickle in, small but every day.
- Mail and maintenance. New patches ship maintenance compensation and login campaigns. Anniversary and special program streams add codes; keep an eye on our ZZZ codes page so none expire unused.
- HoYoLAB check-in and web events. Free, thirty seconds, easy to forget.
Add these up and a diligent free account lands somewhere near 80 to 100 pulls of income across a typical six-week patch, before touching stockpiled savings. Treat that as a planning estimate, not a promise: your total swings with how much event content ships and how deep you clear the endgame.
The save-or-spend rule
Here is the whole strategy in one sentence: decide on the Agent, not the banner. Pull for units you will actually build a team around, skip everything else, and let the savings compound.
A practical version of that rule:
- Only chase Agents that fill a role you lack. A second DPS you will never field is a worse buy than a support that unlocks three teams. If you are unsure who does that, our who to pull guide and the tier list sort Agents by how many teams they enable, not raw damage.
- Enter a banner only if you can reach guaranteed. If you have 60 pulls and no guarantee carried over, you can reliably hit an S-Rank but might lose the 50/50 and walk away with a standard unit. That is fine if you can accept the standard Agent; it is a trap if you cannot. Do not open a banner you cannot afford to finish.
- Skip the weapon banner by default. S-Rank W-Engines are strong, but a signature weapon is almost never worth delaying your next Agent. Free-to-play accounts win by fielding more complete teams, not by squeezing the last 8 percent of damage out of one. The A-Rank W-Engines, plus the free crafting-shop options, cover the vast majority of builds. See the W-Engine and Drive Disc guide for which free weapons punch above their rank.
- Bank through patches you can skip. The discipline that separates healthy accounts from broke ones is sitting out a banner you do not need so the next one is a guarantee with money to spare.
The monthly pass question
Two purchases sit at the border of "free enough to mention." The Inter-Knot Membership is the small monthly stipend that pays out Polychrome daily and is, per dollar, the most efficient spend in the game if you ever intend to spend at all. The battle pass (New Eridu City Fund) is heavier value but a bigger commitment. Neither is required to keep pace with one Agent per patch on a pure free account. They are accelerators, not prerequisites, and this guide assumes you buy neither.
A sample patch plan
Say a patch you care about features a new S-Rank DPS in the first half and a support you already own being rerun in the second.
- Before the patch: check pity on the Agent banner and count your Polychrome. Convert to pulls in your head (balance divided by 160).
- First half: if the new DPS fills a gap, commit only if your savings plus expected event income can carry you to guarantee. Clear Shiyu Defense and Deadly Assault promptly to top up mid-banner.
- Second half: skip the rerun of a unit you own. Bank everything. That saved stockpile is what makes the next must-pull a comfortable guarantee instead of a gamble.
Play it that way for two or three patches and the anxiety drains out of the system. You stop pulling on hope and start pulling on a number you already had in the bank.
Keep building
Once you have the Agent, the pulls only matter if the account behind them is built. Line up your leveling with the material priority guide so a shiny new S-Rank does not sit at level 1, and slot them into a working team with the beginner team compositions. The pull was the easy part; the team is where the game actually opens up.
