Code Break words on the same principle as Mastermind (the game, not the TV programme).

You have 12 attempts to guess a hidden sequence of colours and shapes, and after each attempt the computer tells you the number of correct colours, correct shapes and objects in the correct position. From the information it gives you, you have to work the sequence out.

If you have a TI-99/4A but no Extended Basic cartridge, this type of game is really your best bet, since fast response is not crucial. Arcade games in TI Basic are bound to be a washout.
