The black cube will move on the white tiles in Block Rolling. At the same time, it will not slide, as usual, but will roll from edge to edge and move forward in this way. The game will only last thirty seconds, with a countdown timer in the upper left corner. The cube doesn't move very quickly, and you need to score points by collecting black coins. To speed up, press and hold the down arrow key. The more coins you collect, the more points you get, they are reflected in the upper right corner in Block Rolling.
