Because there is a loophole in Spleef that occasionally allows players to stay in the lobby waiting for victory even after the game has started, I suggest adding arena monitoring to Spleef: after the game begins, if there is only one person on the game arena (on the 3 layers of snow blocks), that person is the final winner, and any other players not on the main game arena (on the 3 layers of snow blocks) are considered second place.
