Minecraft wiki entry for Spleef, associated text: Spleef is played on an easily-destructible block such as snow, leaves, or TNT, with a pit located under the playing field to collect players when they lose. Players destroy blocks on the platform near or under opponents to cause them to fall, while avoiding falling themselves. Those who fall from the platform lose the round, while the remaining players win. Spleef can be played on teams, in 1v1 scenarios, or with multiple players all against each other.
