謎解き学級日誌　クラスで人気のおもしろなぞなぞ is an iPhone game developed by HANA ABIRU. In this game, you play the role of a transfer student who joins a mysterious class. The class diary is filled with riddles, and solving them has become a daily activity for the students.

The game revolves around solving these riddles as a means of communication. To solve the riddles, you need to follow a simple process - first, read the class diary (which contains the riddles), then think of the answers, and finally, tap on the letter panels at the bottom of the screen to submit your answers. If you answer correctly, you will proceed to the next riddle.

If you find yourself stuck and unable to solve a riddle, the game offers hints to help you out. However, be cautious as the hints may give away the answer completely.
