In Narabi, players are dealt 3-4 cards at the start of the round, with those cards bearing either a blank or a number from 0 to 9. Each card is sleeved, and within the sleeve on its back is a rule explaining how this card can be swapped with another card: swap it with a red card, a card with an even number, a card with a higher number, and so on. You can look at all the rules on cards in front of you, but you cannot communicate to others what those rules are. You cannot change the order of cards in front of you.
