About Sin Chess

Sin Chess is a chess game in which you play against the devil of original sin. Rather than winning by eliminating opponents, you aim to collect more resources and claim the final victory. Strategy cards and heroes with different skills shape each game, including in single-player play.

Turn steps

You hold four cards, and each round has three steps:

  • Move step: spend a card matching the number of spaces you want to move.
  • Card play step: spend a card whose icon matches your current site to gain its benefits.
  • Site event step: experience the event at your current site.

Frequently asked questions

Steam lets publishers create keys to sell in other shops. Once you activate a key, the game is yours to keep, just like a store purchase.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
