Remnants of Sin: Deck & Puzzle

Cards Are Blocks. Clearing Is Combat!

A fresh roguelike strategy game that deeply fuses Slay the Spire-style deckbuilding with Tetris-like block-clearing. You play as a condemned "sinner" exiled to the perilous Netherworld, hunting down twisted monsters born of the Seven Deadly Sins to earn your chance at redemption in the Sinless City.

Every card corresponds to a block shape: single squares, bars, L-pieces, T-pieces, and more. Playing a card means placing its block onto the 7x7 board. Only when a full row or column is cleared do the block's attack, defense, or special effects activate.

Beyond numbers and card effects, how you arrange your blocks is part of the strategy. Pre-place blocks carrying powerful effects, then drop that one crucial shape to trigger multi-row, multi-column chain clears. Watch the whole board erupt as your stockpiled damage and effects crash down on your enemies all at once — pure satisfaction.

To aid your journey through the Netherworld, we offer an imaginative Soul Swap system. At rest sites, you can swap the cost and block shape of any two cards in your deck — for example, swap a 0-cost card with a great shape against a high-cost card with an outrageous effect, and instantly "print" your own god-tier card: cheap, easy to place, and devastatingly powerful.

Rich content and depth ensure every descent feels brand new.
