Caps

Caps is a Peg Solitaire adaptation, with bottle caps used in place of pegs. It contains 40 levels, divided into three difficulties. Each level is a specific layout of bottle caps, arranged in a hexagonal grid. The player can remove a cap by jumping a neighboring cap over it, and the goal on every level is to remove all caps but one. It is also possible to turn on "Expert mode", where each level also has an additional requirement which must be fulfilled to finish it, such as removing caps in a specific order or using a particular cap to jump others.

The game also contains an editor, allowing creating levels and saving them in the form of passwords.
