WHAT “CHAOS” MEANS
12 cards, dealt face down.
Each one names exactly what it does. Nothing else about the game changes.
- You are dealt 12.You cannot see your opponent’s hand, and they cannot see yours.
- Play one instead of a move.Teleport a piece, freeze one, reshape the board — the card says which.
- Then it is chess again.A played card is public and permanent. Every other rule still holds.
