TileHack

From the Introduction
This game is the result of a week-long binge session of “Bookworm Adventures”, a life-long fascination with Scrabble and an unholy marriage with Greywulf's ultra-thin Microlite20 version of D&D.
Your characters are dungeoneers in the finest tradition of pen and paper fantasy: elven wizards, doughty dwarven fighters, fighting men of legend, priests of arcane gods, all out to save the Realms from nefarious villains and drooling, evil monsters.
The big difference from standard D&D? No dice. (Mostly. We'll get to the exceptions later). Actions are resolved by spelling words with Scrabble tiles. Spell out bigger words or words using rare tiles to do better. As with Scrabble, the point values of the tiles you use to spell your words will determine your success. Unlike Scrabble, the results show how strongly you swung your sword, how mighty your spell is or even how quickly
you dodged the blade of a sprung trap.
The mightier your vocabulary, the more your characters' fame and power will grow.
