Hey Proxies, if you've been grinding New Eridu like I have since launch, you know Zenless Zone Zero's Signal Search is one of the most generous gachas out there, no soul-crushing rates or predatory traps, just solid pity guarantees and F2P-friendly rewards that let you build a killer squad without breaking the bank. With Version 2.5 live right now, it's even sweeter: you get a free S-Rank Zhao (available all the way through 2.7), a free Jane Doe skin, and well over 110-150 pulls if you're consistent as a F2P player. Whether you're going hard for Ye Shunguang on her current banner or saving for reruns, this guide will help you turn every Polychrome into progress.

ZZZ Gacha System Introduction
What is Signal Search?
ZZZ's Signal Search operates like a well-oiled machine across dedicated channels: Exclusive for limited agents and W-Engines using Encrypted Master Tapes, Stable Channel for evergreen standards via Master Tapes, Bangboo Channel fueled by Boopons, and W-Engine parallels. Convert 160 Polychrome into one Tape pull, or snag Monochrome for paid boosts. Base rates kick off at 0.6% for S-Ranks, climbing through A-Ranks around 7-9%, with the rest B-tier fillers. Access it straight from the main menu, pick your banner, choose single or x10 pulls, watch the flashy animations unfold, and inventory sorts automatically. Version 2.5 introduces Type B Rerun banners with killer perks: 20% discount on the first 10 pulls, no 50/50 risk since you guarantee the selected S-Rank, and pity that carries forward independently. It's a reroll dream for catching up on missed stars like Alice or Anby.
Types of Pull Channels
ZZZ keeps things organized with separate channels for different stuff, and each one tracks pity on its own, so saving across patches feels rewarding instead of punishing.
- Exclusive Channel: Limited 21-day agent banners (two per patch). Kicking off 2.5: Ye Shunguang with team-synergy A-Ranks. First S-Rank is 50/50; lose and next is guaranteed featured. Pity carries over.
- Stable Channel: Permanent standard S-Ranks (Ellen, Lycaon, Rina). New accounts: 20% off first 50 pulls + S guarantee, plus 300-pull selector for any standard S. No 50/50.
- Bangboo Channel: Unlocks at lvl 25. Pick your S-Bangboo target for flat 80-pull pity (A every 10). Switch mid-pity freely, ideal for squad boosters like Sprout.
Resources Used for Pulling
Everything runs on Polychrome, the main currency you farm from dailies, events, exploration, and bosses, 160 Polychrome equals one Encrypted Master Tape for limited banners or a regular Master Tape for standards. Monochrome is the paid version if you ever top up. Bangboos use Boopons only, which come from events, Battle Pass, and missions, you can't buy or convert them directly, so they're pure grind reward.

Basic Rarity Rates
The base odds are the same across most channels: 0.6% for S-Rank, about 7.2% for A-Rank, and the rest B-Rank fillers. What makes it feel good is the soft pity ramp-up and hard guarantees.
- For Standard Characters: Straight 0.6% S-Rank chance split across the permanent pool, no 50/50 to worry about. Clean and simple.
- For Exclusive Characters: Same 0.6% base S-Rank, but half the time it's the featured limited agent, half standard, hence the 50/50. Soft pity starts kicking in hard around pull 75, pushing rates way up until you hit the 90-pull hard guarantee.
How to Pull Characters in ZZZ?
Dive into Signal Search and tab over to Exclusive or Stable Channels. Stock up on Encrypted or Master Tapes from the Polychrome shop, events, or achievements, then tap "Signal Search x1" for suspense or "x10" for bulk efficiency. Limited banners last 21 days each, cycling fresh limited agents with weapon pairs. Your first S-Rank on a limited banner hits a 50/50 coin flip for the featured character, win it, and the counter resets; lose, and the next S-Rank is locked to that featured one. Stable Channel sweetens the deal in 2.5 with 20% off your first 50 pulls, an S-Rank guarantee within those 50, and a full selector after 300 total pulls to pick any standard S-agent like Ellen or Lycaon. Pull history logs everything for easy review, helping you plan the next big drop.
How to Pull W-Engines?
You use separate channel for weapons, using the same Tapes. Hard pity at 80 pulls with soft pity around 70-75. First S-Rank weapon has a 75% chance to be the featured limited one, if you miss, the next is guaranteed. Great for pairing signatures with your new agents.
How to Pull for Bangboo in ZZZ?
Bangboo Channel again: select your target, spend Boopons in x10 batches, and cruise to that 80-pull guarantee. You'll get an A-Rank every 10 pulls to keep things moving. Easy to farm about 80 Boopons per patch if you're consistent, so most players can secure their pick every couple of updates.
Best F2P Pull Strategy
You basically save ruthlessly for limited meta agents like Ellen or Jane Doe, hit 90 pity before banners drop. Leverage selectors on standards wisely. In 2.5, claim free Zhao first, farm extras, then raid Type B Reruns for cheap guarantees. Track every pity counter religiously, x10 exclusively, and ignore off-meta banners. Two patches of discipline = multiple S-Ranks.
How Many Pulls Per Patch in ZZZ?
In Version 2.5, if you're dedicated F2P player, you are looking at 110+ pulls base from dailies, weeklies, Hollow Zero, and events, pushing toward 150+ if you clear everything. Add the free login rewards and you're in great shape.

How to Get the Most F2P Pulls?
Never miss dailies for that steady 60 Polychrome, smash weekly bosses and Hollow Zero runs, devour every event, and cash in achievement milestones early on. Save aggressively for banners you actually want, skip the meh ones and you'll bank enough for full pity plus extras. Always x10, track your counters, and enjoy watching those S-Ranks roll in over time.
Final Thoughts
ZZZ's gacha rewards the patient: 90-pull pity safeties, targeted Bangboos, and 115+ F2P pulls per patch make S-Rank dreams real. Version 2.5's free Zhao, discounted reruns, and Polychrome floods elevate it further, no predatory traps here. Farm dailies, track pity, save for metas, and watch your proxy empire rise. New Eridu's signals call, pull smart, conquer Hollows, and flex that god-roll squad across every update.
