The dice are rolled. The marker on the Countdown card is moved if the next number(s) in the countdown sequence is shown. If none of the sets are rolled and no action can be taken, the marker on the Explosive Power card is moved up and the same player has another turn.
When the Countdown marker reaches 0 or the explosive Power reaches maximum, the player who rolled the dice receives damage points, according to the current Explosive Power. On some explosions, players on either side of the dice roller may also receive reduced damage points.
The player(s) at the end of four rounds with the least damage points wins.
