Just when you thought you had mastered TETRIS! Now we bring you yet another mind teaser from the famed Soviet author of TETRIS, Alexey Pajitnov. WELLTRIS takes you into another dimension as you attempt to position shapes in a three-dimensional perspective. Imagine looking down into a four-sided well with grid-like walls and bottom. Rotate the falling pieces within each wall. But that's just the beginning; you also move the pieces around the side walls in either a clockwise or counter-clockwise direction. Your best score comes from quick, accurate placement of pieces on the bottom grid. Unlike TETRIS you will be removing columns as well as rows in this dimensional puzzler. There are other surprises in store in WELLTRIS, but you just have to see it for yourself. WELLTRIS - another name for "addictive"!
