Crazy Screw

Crazy Screw is a puzzle synthesis and stress-relieving game. U can add 10 screws of the same type on the same bolt to synthesize higher-level screws. Until the target number of this level is synthesized, you can unlock and enter the next level. After the fifth level unlocked, it will appear some unknown screws, making the game more challenging and interesting. If you make a mistake due to carelessness, you can use the [undo] function to make up the mistaken. At the same time, you can also use the [organizing] function to reorganize the screws through the system. After synthesis, screws with different number and type can be distributed by clicking [Distribute] manually. Hurry up! Join the screw army to challenge more advanced and unknown levels actively! Let’s meet at the top of the screw-tightening pyramid and let’s sprint together!
