About This Game

Build the board. Break Hell's score.

Yomino is a dark Japanese roguelike that fuses block puzzles with deckbuilding. Draw a piece from your deck, place it on the board, and fill a row or column to clear it. That simple move, chained through your Relics, snowballs into scores that break the scale.

Where you place it defines your build

Which cell, which piece, which way. Every placement can trigger your Relics, and the same Relic can produce completely different results depending on how you place. It's not just the luck of the draw — your reads change the score.

Discover broken combos yourself

Relics, Patterns, Seals, Editions, Amulets, and Forbidden Arts. Rewrite the pieces themselves, grow the board, and stack your Relics. "What happens if I combine these two?" — that question leads to winning strategies no one has found yet.

Turn the board into a scoring engine

Score = Block Points × Line Points. Which side do you grow, and where do you multiply them? The moment your machinery clicks into place, the numbers explode.

Read through the wardens' handicaps

The warden of each layer imposes unfair handicaps — shrinking your hand, sealing your Patterns, and more. Your build seemed complete; now solve the new problem it faces with smart building and placement.

Into the depths of Hell

A legendary gambler, killed for exposing a cheat and cast into Hell where he never belonged. His only way back to the world of the living: defeat the warden of every layer at "Yomino," the board game the damned play to pass eternity, and reach King Enma in the deepest pit. With a board from his guide, the nekomata, and pieces carved from sinners' bones, the gambler descends.

The more boards and difficulties you take on, the deeper Hell goes.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

How we use generative AI

All final artwork, music, and sound in Yomino are made by our human artists and composer. We do not ship AI-generated art as-is in the game.

We use generative AI as a supporting tool in the following areas:
- Code-driven visual effects (e.g. score orbs flying to the score counter) and some shader effects
- Brainstorming and rough sketches during early art exploration, which our artists then create from scratch
- Temporary placeholder assets during development (replaced before release)
- First drafts of in-game text, which are reviewed and rewritten by the team
- Translation for some languages, reviewed by the team

We will keep this page updated if our usage changes.
