Vice Versa

Whenever we see a game about crossed words formed by letter tiles, we tend to think, "Scrabble". Wörterklauer has almost nothing in common with that ubiquitous game, other than the fact that you cross words orthogonally with letter tiles. The board has no special spaces because there is no score to tally. In fact, all the spaces are designed to facilitate flipping the tiles over.... Wörterklauer works like this: On your turn, you form as many words as you can, then leave the board for your opponent to try to convert letters and words. Any word whose root she can alter by appending to it or changing one letter, any letter she uses in her word, and any crossed words tweaked (you're allowed to change one extra letter in one of the two crossed words), convert to her color by flipping over. If you can't end your turn with more letters in your color than in your opponent's, you lose the game, simple as that.
