Other players aren't always available to provide Competition. Instead, the player can be pitted against the mechanics of the game. These types of games are countless; puzzle games, (or even just puzzles) solitaire games, many ComputerGames, to name only a few categories.

The degree of challenge becomes a critical issue with these games, on the one hand game should be easy to get into, so players don't give up before they get into it, and on the other, there should be NoSkillCap.
