The fuse is lit. The players quickly add more match cards to the ever longer fuse until a player lets the bomb burst by playing one of his bomb cards and then collecting all the matches that are connected to the match start card. Every match card has its value: If you play the bomb card too early, you will not get enough points - if you wait too long, someone else could cut the fuse or trigger the explosion and take the points with you. Hoarding match cards with high values is not a solution either, because they bring minus points if the game with the time bomb suddenly ends.
