1001 Crystal Mazes Collection is a logic puzzle game developed by Teyon for the Nintendo DSiWare.
There is a coin with an image of a girl or a boy that shows a player's current position and can be moved using both a directional pad and a stylus (by touching arrows visible on the touchscreen).
When a crystal is pushed in a corner or two of them are aligned next to each other alongside a wall, they can no longer be moved which causes the player to lose.
The simplest ones contain 3-4 elements, while in the most difficult mazes players have to move over 30 crystals.
1001 Crystal Mazes Collection received an overall score of 7/10 from IGN[3] and a four out of ten stars from Nintendo Life.
