Matching games are games that require players to match similar elements. Participants need to find a match for a word, picture, or card. For example, students place 30 word cards; composed of 15 pairs, face down in random order. Each person turns over two cards at a time, with the goal of turning over a matching pair, by using their memory. For example: Dominoes Board games such as mahjong solitaire Card games such as Concentration or rummy Tile-matching video games Most matching games are objective, with correct answers in the rules for what counts as a match, pair, etc. Some however, like Dixit or Apples to Apples, are about subjective matches picked by one or more judge players. Here the correlation between a match holds value only as other players decide it, but rules dictate who will make those decisions and when.
