Yet another twist on the Tetris style game from Alexy Pajitnov himself, Wordtris is my favorite of these off-shoots. The mechanics are easy to understand, and clearing a word is either satisfying, or relieving, depending on if it was intentional or not. This is sort of also the game's problem, as half the time I'm progressing on accident. The mechanics are mostly good, but I feel the screen space and time you have to plan ahead is too short and uninteresting to keep me hooked for very long.
