JamTris is an exciting and completely addictive puzzle game! Rotate small shapes as they fall from the top of the screen and fit them together to complete solid lines/rows. You can rotate the shapes using the Arrow Keys. Rotate the small pieces as they fall and and fit with the existing blocks to make an solid and complete line. For each line/row removed, you receive points. Receive extra points for removing multiple lines with a single shape.

There are two ways of scoring in the Game of Jam Tris. The first is simply dropping pieces - and making the large blocks with the minimum of one liner block. Receive 10, 5, 3, or 1 point for pressing the spacebar, depending upon the location of the shape when you press it; and the second way to score points is to eliminate lines/rows. Once you have level 10, your game will end, and the score will be reported.
