Tap Speed Test Game is a free game available on the iPhone platform. Developed by Osawa Shunsuke, this game allows you to challenge the limits of your button mashing skills.

The game offers three different modes to test your mashing power: 10-second mash, concentration mash, and 60-second mash. Each mode measures your ability to rapidly press buttons within the given time frame. The concentration mash mode presents smaller buttons, requiring you to focus and press the buttons accurately.

In addition to testing your own skills, you can also compete with players from around the world in the global ranking. The ranking is periodically reset, giving you multiple opportunities to become the world champion of button mashing.

Train your mashing power with Tap Speed Test Game and see how your skills stack up against players worldwide!
