After creating a word, the player rolls a 20-sided die. If the roll does not equal or exceed the value of the word, that player loses a pawn and moves one step closer to insanity. An insane player cannot win.
Published by Playroom Entertainment and designed by James Ernest and Mike Selinker, Unspeakable Words is for 2 to 6 players, ages 10 and up. It takes about 30 minutes to play. The suggested retail price is $20.00.
I've played Unspeakable Words several times and always had a good time. It's a perfect fit for casual word game fans, and you don't need to be a Lovecraft enthusiast at all to enjoy it.
