Atekko Tsuitate (あてっこついたて)

User summary
あてっこついたて (Atekko Tsuitate) is a guessing game.

At the beginning of the game, a theme is randomly determined. Each player write down an answer that relates to the theme on a small white-board, and passes the board to another player. That player stands the board so that only other players can see the answer.

Each turn, you may ask a yes/no question about the answer given to you, and other players respond to it with a thumb up/down. When you are sure what your answer is, you may call out your guess. You win the game if you correctly guessed your answer before everyone else does.
