Coin Bomb is similar to the game Hot Potato! (but you can make money from it...)

Once a bomb is grabbed then the countdown timer will start. The new owner of the bomb has 24h to make sure that someone else buys the bomb after them

When that happens, you get back the price paid AND the interest on top...Failure to do so means the bomb will explode and you lose. Make sure to tell everyone in order to get the bomb out of your hands! Each time the bomb is grabbed the price goes up by the multiplier and there is a small chance of winning an instant jackpot!
