Gem Jam

It is colorful and looks simple and yet it is a challenging and addictive puzzle. The goal is to toggle the colors of the gems, with a minimum number of steps, so they look like the pattern shown on the screen. You will also win gems when you solve the puzzle. It's not that easy! When you tap a gem not only it changes its color but also the colors of its neighbors. You must plan your moves carefully, or you will find yourself in a bit of a jam. If you are in trouble you can use the help button to show you the correct move, but it will cost you one gem. There are plenty of levels to play for a long time and new ones will be added in future updates of the game. You won't get bored for sure!
