Asriel, at the hardest level that program thinks ahead only three half-moves. This means that it is a lousy program. Kaissa could easily be implemented in Zillions, when it would be much better. Zillions also costs $20, but then you get a much stronger program, and you won't only get one variant but thousands, many of them more interesting than Kaissa. If you buy Zillions then you can implement Kaissa yourself, provided that you won't publish the game (while it is copyrighted).
