Rules

The first player chooses a letter of the alphabet.

The each following player then chooses and adds another letter.

At anytime a player may challenge another's choice of letter. If they cannot complete the word to make a real word then that player loses the round. When a player loses, they get an imaginary 'D', then 'O', etc. The first player to lose 6 rounds in total ('DONKEY') loses the game.
