PLTjewel

The game is very simple. There is an 8x8 array of jewels of 7 types. You need to get 3 or more in a row horizontally or vertically in order to score points. You can swap any two jewels that are next to each other up and down or left and right. The mechanic is to click the mouse on the first one, then drag in the direction to switch with. Then let up the mouse button, but this last isn't so critical.

Jewels can only be swapped if after the swap there are at least 3 or more same shape or color in a row or column. Otherwise the jewels return to their original position. There is a clock shown on the left. When it counts down to 0 the game is over. The high scores are stored in $HOME/.jewelscores

Hit spacebar to start a new game then select the difficulty number by pressing '0', '1', '2', '3' or '4'. You can always press 'ESC' to exit. During playing press 'p' to pause the game.

The code is a conversion of Dave Ashley's C program (GLjewel) to Scheme with some modifications and enhancements.

Enjoy.
