Games that challenge the player with critical thinking to solve levels. 

Games that are normally played on a table or other flat surface, such as board games, card games, dice games, miniature wargames, or tile-based games

A turn-based game mechanic is the opposite of a real-time game mechanic. In a Turn-By-Turn mechanic (synonym), each player has to wait for the other to have played, so that they can play, and so on. This way, each player has the time to think about their strategy. TBT games rely less on action than real-time games.
