Turnover

A word game that has elements of Reversi in that you turn over letters to your colour when you form a word.
2 player or a 4 player (partnership) game. Each player uses an identical set of 50 tiles, one marked with red, the other blue.
The first player lays down a letter, the second player lays a letter beside it (at the back or front). Play continues like this. If a player forms a word, all tiles in that word are turned over to his colour. Words are built up crossword fashion.
When all the letters have been used, the winner is the player with the most of his colour in the crossword.
