Signal Search is Zenless Zone Zero's gacha. Limited pulls use Encrypted Master Tapes (160 Polychrome each); the standard channel uses plain Master Tapes at the same price. The structure is the HoYoverse standard with one genuinely unusual addition. [[1]](#ref-1)

## Channels

| Channel | Featured | S-rank base rate | Hard pity | Featured guarantee |
| --- | --- | --- | --- | --- |
| Exclusive Channel | 1 limited S-rank Agent | 0.6% (1.6% consolidated) | 90 | 50/50; loss guarantees the featured Agent next (worst case 180) |
| W-Engine Channel | 1 limited S-rank W-Engine | 1.0% (2.0% consolidated) | 80 | 75/25; loss guarantees the featured W-Engine next (worst case 160) |
| Standard Channel | none, permanent pool | 0.6% (1.6% consolidated) | 90 | none |
| Bangboo Channel | player-selected Bangboo | 1.0% | 80 | selection, not chance |

Pity carries between banners of the same channel type. Community measurements put a soft pity ramp near pull 75 on the Exclusive Channel; HoYoverse does not publish soft pity values, so that number is a community-documented estimate. There is no Capturing Radiance equivalent as of July 2026.

## The Bangboo Channel

The Bangboo Channel is the unusual part: it pulls the game's companion units using Boopons, a currency earned in play and not sold for real money. It has a 1% S-rank rate, an 80-pull guarantee, and lets the player choose which Bangboo the guarantee targets. [[1]](#ref-1) A gacha wheel with no cash input is rare in the genre and worth knowing about when comparing monetization designs.

## W-Engine notes

The W-Engine Channel's 1.0% base rate is the highest equipment rate among the HoYoverse games (Genshin Impact's weapon banner is 0.7%, Star Rail's light cone banner 0.8%), and the 75/25 with loss protection caps a featured W-Engine at 160 pulls.
