Oshi Chau?

Oshi Chau? (おしちゃう？) is one of the six microgames made by Sekai no Nabeatsu with WarioWare: D.I.Y. for download in the category Big Name Games. It was available in Japan from April 29 to July 10, 2009.

Gameplay
A very simple math problem appears on the screen in three parts in succession, namely "3", "+ 6" and "= ?", forming "3 + 6 = ?". Three numbers are given as possible answers in the lower part of the screen, specifically "2", "9" and "11." While the second number would actually be the correct sum, the game's instructions at the beginning assign the player to do nothing. When tapping any of the numbers, the player loses, as he or she ignored the instructions, meaning that the game can only be won by not doing anything. The math problem is intended to trick the player to tap a number nonetheless due to its simplicity.
