The virtual world is constantly being built using puzzle rules. In particular, in the game DropTris you will stack colored figures from blocks. It's like classic Tetris. The task is to form solid horizontal lines at each level; you need to create a certain number of them. There are twenty-seven levels in total, and the number of lines will increase on each. You will see all information about assigned tasks and progress on the right side of the vertical toolbar. It's very handy to see the next block to be served so you can prepare in DropTris.
