Waifu Sweeper is a logic-based puzzle game on Abstract that layers collectible anime characters — Waifus — on top of classic Minesweeper mechanics. Developed by Raitomira and published by YGG Play, it launched on Abstract in January 2026 as part of the "Casual Degen" genre.

What is Waifu Sweeper

Waifu Sweeper takes the tile-uncovering logic of Minesweeper and turns it into a skill-to-earn experience. Players navigate boards to uncover hidden treasures while avoiding monsters, using deduction and available clues rather than relying on luck. The game is positioned as a contrast to traditional gacha titles: rewards flow toward players who demonstrate puzzle-solving proficiency.

Gameplay

Each run challenges players to clear boards by reasoning through tile states — a format that rewards pattern recognition and calculated risk. Waifus serve as collectible characters that accompany players through dungeons and can be upgraded via a gacha system. Waifu Rush, introduced in March 2026, adds a weekly competitive leaderboard with prize pools for top finishers.

Economy & Assets

The game uses an Energy-based economy for competitive play and introduced a CHAD token to support leaderboard progression and in-game benefits. Raitomira's "skill-to-earn" model aims to distribute rewards based on gameplay merit rather than randomness.

Team & Backing

Raitomira was founded by Hun Pascal Park (ex-Blizzard Entertainment) and Karan (ex-Tencent). The studio operates under the YGG Play publishing umbrella — Yield Guild Games' dedicated Web3 games label — which supports Abstract Chain titles targeting mainstream casual audiences.
