Challenge the limits of your button mashing!
Well measure your mashing power in 10 second mash, concentration mash, and 60 second mash!
Train your mashing power for when you need it!
In the concentration mash, the buttons are smaller than in the 10 and 60 second mash, so you need to concentrate to press the button properly.
You can also compete with people from all over the world in the ranking.
The ranking is reset periodically, so you have as many chances as you want to become the world champion.
