The "clear the board" game is still in Puzzle Quest 2. It is the mini game you play when you learn a new spell from a NPC (though I've only encountered a goblin witch in the orc floor that teaches spells). Also, I seriously hope they make a patch to fix the 'dumb' equipping and that someone makes a handy chart of what upgrades to what. So far, Hellforged seems to get +weapon critical as a perk when you upgrade it enough, Ancient gives +defense, and Glyphic gives +spell resistance. Happily, at level 21 you can restat, if you have the patience (instead of just starting over when you realized you completely gimped the barbarian...)
