This game is exactly what you think of it. It is a classic arm wrestling game. Here, instead of using your strength, you need to press the button at the right time to win the match.
How to play:
You'll notice the bar at the right-hand side of the game screen with the left arrow at the bottom. You need to click the left arrow to make your move. And the bar that indicates your strength level. Higher the bar, higher the strength. So you need to click the button at the right time to make an impactful move.
Instead of clicking the button continuously, you need to click the button when the strength is high.
