Watchamacallit Puzzlewords (1983)

Each player thinks of a subject and secretly writes words relating to it on a planner, like a little crossword. The other players call off positions on the board, finding the letters that make up the words. By challenging and naming a word before it is complete, players can earn bonus points, but lose points if they are wrong. Puzzlewords will increase your word power and provoke laughter and discussion all around the table.
