Excellent written applet by LunaTic. It is a cross between tetris and columns
(3 or more of the same colors disappear) with enhanced manouvrability.
You can move blocks in all four directions. Easy gameplay that can be addictive.
Try it out !
Use your numpad keys as follows:
8 - UP.......5 - DOWN.....4 - LEFT..... 6 - RIGHT
If you have 3 or more of the same symbols on a row (horizontal, vertical, diagonal)
they will disapear and you will get points for it.
