Board Games - Solo/Solitaire
These are board games that have a mode intended for play by a single player. In most cases, the single player must defeat the game itself which takes automatic actions to thwart the player's progress or attempts to win the game or scenario.
Many Solo/Solitaire games also have a Cooperative mode meant for multiple players. The game framework for these types of games is highly similar since both of them revolve around playing against the game or scenario.
