Second-guessing game with just 11 cards in the deck. Players select cards simultaneously; high card wins unless it's more than twice the opponent's play. Losing card is returned to its owner's hand, while the winning card is scored.
Card distribution is slightly different than that of Pico 2. Pico cards run 2-10, 13 and 16. The later version, Pico 2, sees the cards run 4-13, 16.
