Claro is the clearest card game in the world. Everything is clear with no more than two rules: 1. "Always play a card!"… well, that was clear. 2. "Be the last player who can do this!"… again, totally clear. It is also completely clear that each card allowed is clearly higher than the one previously played. Clearly enough, stars of the same color on two cards are also OK. Exciting. Captivating. Claro.
