About game
At the beginning of the game, several simple patterns will appear. These patterns are tightened with screws, and the player needs to press the wrench to remove the screws. As the wrench unscrews more screws, the subsequent levels will become more difficult. Use your brain to unscrew and collect more wrenches.
How to play
Mobile phone operation: Click the screw on the screen to get the wrench.
Computer operation: Use the mouse to click the screw on the screen to pick up the wrench.
