The Floor Is Lava

Someone calls out "the floor is lava!" at any point during regular play or as a planned round.

From that moment, no player may touch the bare floor; everyone must climb onto furniture, cushions, or other safe objects.

Players move across the room by stepping only on approved safe surfaces, without touching the ground.

Anyone who touches the floor is out for that round, or must go back to the start, per house rules.

Set a time limit or a destination goal; the last player still off the floor, or the first to reach the goal, wins.
