Chess, or chess with cards.

Pick a door and a real board opens immediately, against the computer. The clock, its strength, and human opponents are all one tap away once you are already playing.

WHAT “CHAOS” MEANS

12 cards, dealt face down.

Each one names exactly what it does. Nothing else about the game changes.

  1. You are dealt 12.You cannot see your opponent’s hand, and they cannot see yours.
  2. Play one instead of a move.Teleport a piece, freeze one, reshape the board — the card says which.
  3. Then it is chess again.A played card is public and permanent. Every other rule still holds.
