Well, it involves the creative problem-solving skillset of
Rummikub, but you play with Scrabble tiles. It retains the scoring system of the Scrabble tiles, but operates free-form with no board. Because the number of possible tile combinations includes any Scrabble dictionary allowable word, as well as the crossword-style connections and tile sharing, it increases the amount of possibilites one has to weigh against when scrapping/rearranging the whole board and getting it back together before the sand runs out.
I thought this would make it more complex, and therefore more difficult, but in fact it was very easy to fly by the seat of your vocabulary-pants and throw something together.We set out trying to determine a set of restrictions that would make the gameplay more difficult, but not so difficult as to lock up the game and force too many "draw" turns or weak moves. In short, we got drunk and never developed a proper system of rules.
