Blockers is an interesting puzzle game for Symbian phones that will test your powers of logic.
The object of Blockers is to clear the screen of colored blocks. You do this by clicking on two or more joining blocks of the same color. When a grouping is made all of these blocks will disappear and the rest of the blocks will fall. If there are blocks left at the end of the game which can't be grouped, then it's game over.
Blockers is a very simple game to play - you just tap on a colored block to make a match. However, it's fiendishly difficult to master, especially as you progress up through the levels and there are multiple block colors to contend with.
You might feel that Blockers is a bit too basic - there's only one game mode and no settings (not even a tutorial).
It may be simple, but Blockers is still a fun way to pass some time, which will get your brain ticking.
