Burning the double reward on a $4.99 pack while ignoring the $0.99 tier, or cashing all six bonuses the night before the anniversary reset — such slip-ups leave Proxies hundreds of Polychromes short of their Ellen Joe pity. The ZZZ first top-up bonus is a one-time 100% boost on each of six independent Monochrome tiers; misuse it and that value vanishes until the annual reset around July 4th.

What Is the ZZZ First Top-Up Bonus and How Does It Work?

Monochromes convert 1:1 into Polychromes, and the first purchase on any tier doubles the base amount. Every tier stands alone — buying the $99.99 bundle does not consume the $4.99 bonus. The table below shows the raw Monochrome numbers before and after.

During the double window every tier delivers roughly 120–130 Monochromes per $1, compared to ~80.8 for a post-bonus $99.99 pack. The shop UI marks live bonuses with a “2x” icon or a “+[Base Amount] Bonus” label; a shrunken number like “+1,600” means the tier has been consumed.

The Optimal Spending Hierarchy: Monthly Pass First, Top-Up Ladder Second

Priority one never changes: the Inter-Knot Membership ($4.99). Its upfront 300 Monochromes plus 90 daily Polychromes yield ~600 Polychromes per $1 — a multiplier no top-up tier touches. Next comes the Battle Pass (New Era / Growth Plan). The Encrypted Master Tapes and leveling mats save thousands of Battery Charge, shortening the grind to Drive Disc farming and Daze-optimized teams.

Only after stacking both should you climb the First Top-Up Ladder. Buy each tier once, from $0.99 to $99.99, to bank every double reward. The per-dollar efficiency stays flat across tiers, so there’s no penalty for starting small.

Timing Strategy: Anniversary Resets and the 'Use Before Reset' Rule

HoYoverse resets the First Top-Up Bonus annually, historically around ZZZ’s July 4th anniversary. Exhaust all six tier bonuses before that reset, and you unlock a completely fresh double-bonus cycle — effectively doubling lifetime Monochrome yield. Stacking multiple Monthly Pass purchases (up to 180 days) during bonus windows also gives instant 300 Monochrome payouts without touching the top-up tiers.

Where to Recharge Cheapest: Official vs. Third-Party Platforms

Official channels — the in-game store, HoYoverse Top-Up Center, Codashop, Razer Gold — mirror the same USD baseline with zero risk. Third-party platforms, however, leverage regional pricing differences to lower the effective cost per 100 Monochromes, a meaningful edge for Proxies who have already consumed their double bonuses.

Many veteran Proxies rely on LootBar Recharge (https://www.lootbar.com/top-up/zenless-zone-zero) as a reliable option for cheaper ZZZ top-ups, leveraging competitive regional pricing with a straightforward process — especially when double bonuses are gone and every Monochrome counts.

Final Checklist: Maximizing Every Monochrome Before You Pull

• Check the shop for a “2x” icon on all six tiers before spending; never buy a tier twice at full price while a double-bonus tier remains unclaimed.

• Hold Monochromes until pull time. Exclusive Value Bundles occasionally appear that beat the flat 1:1 Polychrome conversion.

• For post-bonus standard top-ups, compare platform pricing once — the compounding difference across a whale-tier spend cycle can match an extra multi-pull.
