S'Lots of Gems

Pull the arm, roll rows and columns of gems, and make them match. Watch the gem lamps and how they are lit, as two lamps make the corresponding gem reducted from the next turn (arm pull). Score up, make credits for even more turns!

Use the mouse cursor to left click on the arm and the arrows. You can restart any time by pressing the RESTART button. Press QUIT to exit the game. Press the + and - signs to manipulate sound volume.
See every relevant rule in the game, on the left side of the screen.

EDIT: I found some bugs and errors in my code which let the game score up for intersecting matches. I fixed it, and that basically made the game harder a bit, so I changed the scoring too. (I reserve the right to make changes later).

EDIT 2: I upgraded the how to play making it more like a tutorial. Added a ? button, if someone wants to turn this off. I added the goal score for the next 10 credits under the score.
