Traditional Chinese card game, similar to the Thai game Red Frog Black Frog and the Indonesian Main Merah. It is playable with a regular poker deck. 24 cards are distributed evenly among players, and four are dealt face-up to the table. On a player's turn, they play one card from their hand: if it pairs with another card on the table (if the two cards add up to 10, or if the cards are the same rank above 9) the player captures them both. The player then flips the top card of the deck to the table and captures with that if possible. Cards which don't capture stay on the table. The game continues until all cards have been captured - with some unlikely exceptions, the last card flipped will always capture the one remaining card. Players score their captured cards: red 2-8 are face value, red 9-K are 10 points each, red aces are 20. Black cards are worthless, except: with 3 or 4 players, the ace of spades is worth 30; with 4 players the ace of clubs is worth 40. Highest score wins. —user summary
