Spicy Chess
Chess is a very old game known to everyone to some extent, so we won't explain the rules here. However, we have a special addition to the rules to make it quite spicy and sure to be a good incentive to get into the game.
The addition we're talking about involves assigning a "consequence" to the capture of each piece. Of course, the consequence will depend on the importance of the piece (from least to most: pawn, knight, bishop, rook, queen, and king). For example, if your pawn is captured, you'll have to give the other player a passionate kiss. If it's a knight, well, you'll have to do something a bit more daring, like removing an article of clothing, giving a little massage, etc.
You can also reward certain classic moves like castling, check, or checkmate. The player who performs a castling or gets checked must also suffer some consequence. As for checkmate, we propose that the winner of the game gets to have their wish fulfilled, because they won!
