Dating game shows are television game shows that incorporate a dating system in the form of a game with clear rules.
Human matchmaking is involved only in selecting the game's contestants, who are usually selected more for the amusement value than any concern for their happiness or compatibility.
Some gay and straight romances have been sparked on the other reality game shows, suggesting that they too may really be "dating shows" in disguise.
