Egyptian Ratscrew

Deal the entire deck evenly among all players, who keep their cards face-down without looking at them.

Players take turns flipping their top card into a shared central pile.

If a flipped card matches specific patterns, such as two cards of the same rank in a row or a rank sandwiched between two matching ranks, all players race to slap the pile.

The fastest player to slap correctly on a valid pattern collects the entire pile and adds it to the bottom of their own deck.

A player who slaps the pile when no valid pattern is showing must give a card as a penalty to the pile or another player.

The game ends when one player collects every card in the deck.
