Ttakji

Each player sets one of their own folded paper tiles on the ground as the target.

Take turns throwing another tile from your hand down hard onto or beside the target tile.

If the impact flips the target tile over, you win it and add it to your stack.

If the target stays put, your turn ends and play passes to the next player.

Keep playing until players agree to stop; whoever has won the most tiles overall is the winner.
