A permutation is a combination of objects in a specific order. This concept helps describe the overall objective of the game, to guide colored blocks down a transport puzzle to reach pre-determined destinations in specific order. A better name for the game, perhaps, could have been "Great Iterator", not because the grueling puzzles in this game often require trial&error problem-solving, but because they frequently must be constructed such that blocks loop through the puzzle several times, interacting with puzzle pieces multiple times until the puzzle’s conditions are met.

The puzzles can be solved with two different types of pieces. These are the conveyor, which move a block to the adjacent square in the direction in which it is drawn, and devices, modifier pieces that may change the block’s color, that have variable points of output, that collect blocks and releases them simultaneously when enough are inserted and so on. The puzzles require patience and lateral thinking. They are very difficult, particularly if you try to solve the puzzles in the fewest number of moves possible. With 50+15 boards and a built-in editor, Great Permutator has more than enough content to satisfy those who appreciate genuine challenge.
