Adjunct Blaster

If you are a fan of the classic Tetris game, then you should try this new variant called Adjunct Blaster.

I'm sure you will spend some hours in front of your PC with this simple and fun tetris-style game. The best features are the new special tiles that will let you play in a different way compared to the classic Tetris.
The main goal of this game is to clear tiles from the game grid. This can be done by joining the tiles of the same color together. When there are four or more tiles of the same color, they will simply disappear. One nice feature is that the tiles will be cleared in vertical and horizontal way, no matter how they are grouped.
Moreover, there are two special tiles that at intervals, will fall down from the top together with other tiles. One of these tiles is a mysterious one that will hide its color until it is placed in the grid. The second special tile will show a kind of arrow, and once it is placed on the grid, all tiles of any color to the left and right will be cleared.
Finally, this addictive game is a lightweight program, does not need special hardware requirements, and it's totally free.
