Jewel Fighters is an addictive puzzle game, where you fight people until you manage to lose a fight. To attack, you must explode a Jewel with the use of a bomb, the more Jewels chained together, the more damage that is done. The damage caused by the amount of chained Jewels increases exponentially, so the gap between 2 and 3 is larger than the gap between 1 and 2.
