Solo Chess

Solo Chess is a chess-inspired roguelike deckbuilder. You place chess-piece cards on a 3×3 board, use their effects to build combos, score points and clear waves of tactical challenges. Runs use an escalating series of challenges, with each board layout and card draw presenting a new puzzle.

Cards and scoring

You start with a 16-card deck of Pawns, Knights, Bishops, Rooks, Queens and Kings. Each card has a scoring effect based on its piece’s traditional movement. Matching specific rank sums, such as 4, 8 or 12, triggers combo bonuses, so placement and arithmetic shape your scoring strategy.

Café visits

Between waves, you visit a café to adopt pets, choose food and use tools to change your deck. More than 40 pets provide passive bonuses, while food grants temporary buffs. You can also upgrade a card with Promotion, remove one with Sacrifice, or open a Mystery Gift for a surprise effect that can be risky.

Deck options

The game has 10 difficulty levels and multiple unlockable decks with different starting setups. Charms and bindings grant extra card powers, while collectible auras provide three visual variants per card. Café visits also offer deck upgrades, removals and surprises.
