Boggle - this unreleased game for the Atari 2600 is programmed by David Crane, when he was still working at Atari. The Boggle game, which is based on the popular word game of the same name, you need to form as many words as possible from a random grid of letters 4x4. In the 2600 version of the game for two players, and each player can collect no more than eight words (probably due to lack of memory in 2600). Boggle game, seems to be pretty close to completion, although there are some shortcomings caused by glitches, for example, all the letters in the grid does not appear immediately when you start the game. Still, it's an interesting prototype and it is unknown why the Boggle game was not completed and released.
