Each game begins with a board, a number of "PegIts", and limited number of jumps. Remove all but one PegIt in the allotted time, and you win. Otherwise, you lose. A PegIt is removed when another PegiIt jumps over it. Each pegit can only move by jumping, and it moves two spaces horizontally or vertically. It cannot land on an occupied square. Sound simple? Did I mention the trampolines?
Yeah. Pegit provides all kind and manner of unusual squares. There are squares which hurl a peg forward like it was shot from a cannon, trampolines which bounce you over a square, 'time warps' which move you around the board, even explosive squares. The game is, in some ways, reminiscent of the old game "Lemmings", in that you must solve puzzles by the use of various special abilities. Often, there is only one solution and a few thousand wrong ones. At low levels, solutions are provided . . . at higher levels, you're on your own. Since there is no random element, in theory, you can solve any problem simply by studying the board and playing it in your head. Well, maybe you can. I'm not bright enough.
The trial/demo version of PegIt includes only the first 20 levels, but there are many more to master in the full version. Since each level is pretty much over once you've solved it, the replay value of the demo version is somewhat limited. However, there's enough there to know if you like the game, and if you do, it only makes sense to buy the full version.
If you're looking for a fun, easy-to-learn-and-hard-to-master puzzle game at a reasonable price, try PegIt.
