Great app, helps in boosting concentration.Perfect workout for the brain with the timer set on. Need to fix some glitches and errors in the arena mode coz the screen goes blank and the score gets calculated automatically giving opposition an advantage. Still a great app. Great job......Plz fix the errors in arena mode.Thx.
Great game Cant get the notification to go away. Not even sure what they mean. I have tried to remove allllll notifications for this app. I see a number 5 next to the app
