The floor is lava, run by your phone. Green means walk around and do the silly challenge. Orange counts down 3, 2, 1. Red means get your feet off the floor. Every round gets faster, and sometimes the countdown is a fake out.
Classic runs for 3, 5 or 10 minutes, or forever. Last One Standing knocks out anyone caught on the floor until one winner is left.
Long gentle warnings for toddlers, fair rounds for families, and surprise lava with fake outs for the big kids.
Hop like a bunny, walk like a robot, touch something red. Forty challenges keep the safe rounds moving.
Countdown beeps, lava music and vibration, so everyone knows the moment the floor turns. Plays even on silent.
