1 board,
1 Sand glass,
1 dice cup,
13 dice,
1 block

The dice show the different characters of the alphabet with a point score. The rarer a character, the higher the value.
The active player throws 13 dice, and the sand glass starts to run.
Now the player has time to bring the dice into right order at the board so that they lay crossword like at the board.
The sand glass limits the time.

Now the points are counted. Not used characters bring minus points.
