Zenless Zone Zero’s 4 Billion Polychrome Split: A Lucky Proxy’s Guide to Bangboo Badges
Zenless Zone Zero’s four billion Polychrome event runs Feb 14–25 with daily Bangboo Badge prize pools, turning check-ins into share-based rewards.
Zenless Zone Zero has decided that February is the perfect month for Proxies to test their luck, because from February 14 to February 25, 2026, a four billion Polychrome event turns daily check-ins into a miniature carnival of possible riches. The whole affair unlocks once a player reaches Inter-Knot Level 5 and completes the Main Story Prologue event unlock from “The Hare and the Proxy.” Think of it as a vending machine that accepts Battery Charge instead of crumpled bills, and occasionally spits out a shiny badge that makes everyone else’s prize slightly smaller.

How the Daily Prize Pools Work
Between February 14 and February 20, seven Daily Prize Pools open one after another. Each pool contains four distinct rewards, including Polychromes and a Bangboo Badge, with equal odds and no repeated pulls. The Bangboo Badge is the real treasure: the instant a Proxy draws it, every remaining reward in that pool is automatically awarded. It is much like yanking the right thread in a tapestry and watching the whole pattern unravel into the Proxy’s inventory.
The daily rhythm is simple but strict. Every login gives one free draw. Spending 30 Battery Charge grants one more draw attempt, up to three extra attempts each day. Attempts reset at 04:00 server time, and any draw attempts earned on a given day expire when the next day’s pool begins at 03:59:59. A player who hoards them like a dragon sitting on a pile of expired coupons will not be rewarded.
The Two-Phase Prize Split
| Phase | Pool Dates | Badge Series | Max Shares | Total Pot |
|---|---|---|---|---|
| Phase 1 | February 14–16 | Lucky series | 3 | 1.6 billion Polychromes |
| Phase 2 | February 17–20 | Gilded Carrot series | 4 | 2.4 billion Polychromes |
The math is where the event gets pleasantly strange. A Bangboo Badge is not a fixed reward; it is a share in a communal pot. In Phase 1, the pot is 1.6 billion Polychromes, and one Proxy can hold up to three Lucky series badges. In Phase 2, the pot grows to 2.4 billion Polychromes, and a Proxy can hold up to four Gilded Carrot series badges. If 16,000,000 badges are drawn in Phase 1, each badge would be worth 100 Polychromes, because 1,600,000,000 divided by 16,000,000 equals 100. A three-badge Proxy would get 300 Polychromes. When the result is not a whole number, it is rounded to the nearest integer, sparing everyone from the heartbreak of fractional currency. The badge’s value shifts like a soup kitchen portion that depends on how many bowls arrive.
Every Daily Prize Pool, Hour by Hour
Phase 1 pools run on server time as follows:
-
February 14 Prize Pool: 2026/02/14 04:00 – 2026/02/15 03:59:59
-
February 15 Prize Pool: 2026/02/15 04:00 – 2026/02/16 03:59:59
-
February 16 Prize Pool: 2026/02/16 04:00 – 2026/02/17 03:59:59
Phase 2 pools continue immediately after:
-
February 17 Prize Pool: 2026/02/17 04:00 – 2026/02/18 03:59:59
-
February 18 Prize Pool: 2026/02/18 04:00 – 2026/02/19 03:59:59
-
February 19 Prize Pool: 2026/02/19 04:00 – 2026/02/20 03:59:59
-
February 20 Prize Pool: 2026/02/20 04:00 – 2026/02/21 03:59:59
Settlement Schedule and Global Timing
Daily pools follow server time, but the shared reward settlement happens globally. Phase 1 settles on February 17, 2026, at 20:00 UTC+8. That translates to 13:00 UTC+1 and 07:00 UTC-5. Phase 2 settles on February 21, 2026, at the same hour. Because regional pool end times vary, the shared reward distribution may trail a little behind the last pool of a phase. The full event window runs until February 25 at 03:59 server time, but after February 20 there are no more daily pools to pull from. Late arrivals can still see the results, but they will not be able to scrounge an extra badge.
A Strategy for the Mildly Superstitious
Since each pool has only four outcomes and no repeats, the fastest way to reach the badge is to use as many draw attempts as possible before the server clock flips. Players who want all seven possible shares should plan around Battery Charge spending and daily resets. The whole event is like a reverse lottery: the more badges the entire community pulls, the smaller each badge’s final payout becomes. It is also a subtle reminder that even a mountain of Polychromes, when divided across millions of players, turns into a few polite coins and a warm feeling. The warm feeling may not survive a lost 50/50, but that is a problem for another day. Happy pulling, and may the Bangboo Badge appear before the battery runs dry.
Data referenced from PEGI helps contextualize why a limited-time, luck-driven event like Zenless Zone Zero’s “4 billion Polychrome” giveaway leans so heavily on daily resets, capped attempts, and clear phase settlement times: transparent rules and time windows make randomized reward distribution easier for players to track and for publishers to communicate responsibly, especially when outcomes depend on community-wide participation and shared pots rather than fixed payouts.
