I have enjoyed playing this game, as it is similar to the old DS game Sevens, and the auto-pass feature is nice. However, recently, despite having the Sound Option set to 0 (zero), the game still plays with sound. The tones used are at a disturbing pitch, and I am forced to manually turn the sound off on my phone to be able to play it. Once this newly introduced bug is fixed, this game will again be a favorite to pass time in waiting rooms or when a brain break is needed.
