...For Everything Else, There's MasterYourEmotions

The way this apparently works is that you place a "special prize" (AKA a $20 - if that ain't love I don't know what is), and the lucky recipient must solve the puzzle in order to attain said prize.  The only thing that would add to this product's potential for aneurism-inducing rage would be the addition of superglue to prevent the recipient from being able to open the game, even after they have won.
