In this game, you play as a cartoon swordsman and fight off the forces of the evil Amethyst and Emerald Kingdoms, who have encroached upon your borders. Get coins to buy better weapons and armor, and destroy 15 spawners to win. You will travel across a random map made up of various tiles. These may include hills, pools, spawners, forests, and buildings full of gold.
Here is two rounds of Jewel Wars in action. No victories: once I was swarmed by amethyst soldiers, then once by sorcerers. Sorry about the choppiness. If you want to see what gameplay looks like, here's your video.
