Blind Baseball is a poker game where several cards are dealt to players but they are kept face down and put in a stack in front of the player. The number of cards can vary depending on the number of players but seven cards each is common.
Play starts to the left of the dealer with the player turning over his first card. This is now obviously the best hand and the player may bet. Each successive player in turn then exposes cards until he beats the best hand or runs out of cards and is therefore out.
