Square Tower

Это никогда не так просто, как вы думаете,

The engineers need your help to finish building the famous black and white tower. They show you whether they need white square or black square. In each case you must make sure to give them exactly what they ask for.

There are three squares at the bottom. Tap one of the side squares with the same color as the middle square to collect it. But be aware that the color of the side squares could change the next time around.
