Five playing levels are included along with a 'Hint' feature (for level 1) in case you get stuck.

The object of the Gem Game is to "mine" the gems from the playing board.  To do this, you can shift any two adjacent (horizontally or vertically) gems.  In order to successfully "mine", you need to create a row or column of at least 3 similar gems.  When you do, the gems will be pulled from the board, those above them will drop down, and new gems will fall into place at the top.

If you need help, you can hit the 'Hint' button on level 1, but it will deduct 50 points.  Levels 2 through 5 are for the advanced players, as they have time limits imposed (With additional time granted for each successful move).
