かけひきじゃんけん
先に宣言、あとで勝負！
Only for iPhone
Free
iPhone
Declare first, then make your move. Outsmart online opponents or enter the same-rule weekly CPU challenge in three quick rounds.
Bluff Janken is a mind-game twist on rock paper scissors. First, everyone declares a hand. After all declarations are revealed, choose the hand you will actually play.
An honest win scores more points. A well-timed bluff can still turn the round. Read each declaration, online win rate, and honesty rate, then compete for the highest score across three rounds. Online waiting phases have a 40-second limit. A timeout or disconnect does not count toward your record, and the app offers recovery choices to search again, play against CPU, or return home.
