Stack Up description
Puzzle the player's task which is to place the same falling figures (it should be noted – very funny, such will not find anywhere else) groups of three identical, then they will disappear. The ultimate goal is the destruction of entire lines of figures (but horizontal). Speed falling shapes is very high.
Formally, the size of all the figures there are the same, therefore any "gaps" between the combinations can not be. At each level set to a specific number of lines that must be destroyed (usually four or five). Overall, a good puzzle is not very difficult and "annoying", it is quite suitable for resting.
