In Stone Bridge, you are controlling a large crane that is dropping stones to make a bridge across the water. The crane sways back and forth as in real life, so placing the stones won't be easy. Once you place the first stone on one of the other stones, you'll have to keep connecting stones to that piece you placed. If you miss the stones three times, you lose and have to start over. Building the bridges will get harder and harder with each level. Just use your mouse to release the stone in the crane where you want it placed. It sounds simple but it's super challenging and fun!
