Boom-O is a simple elimination card game from the makers of Uno. Each player gets 7 cards in hand and three time bomb cards in front of them. Most of the cards in the deck either increase or decrease the timer total. Other cards include familiar commands such as Skip, Reverse, Draw 1 (or 2) and Trade Hands. Player discard one card per turn trying to clear their hand while keeping the timer total under 60. If a player can't play a valid card, they must flip over one of their three time bombs. If a player clears their hand, all other players flip one of their time bombs. Whoever flips all three of their bombs is out of the game. Survivor wins. Re-implements: 5 Alive
