Circle of Richness M4 is a MultiJoy hack of a game known as Wheel of Fortune.
The game can be played by up to four contestants who are solving word puzzles similar to those seen in the popular TV show. The winner of four basic rounds qualifies to the final round.
Circle of Richness M4 is mostly controlled by joysticks. The keyboard is needed only when entering the complete solution of the word puzzle.
The game requires Atari XL/XE machine with at least 48 KB of RAM and, obviously, the MultiJoy interface. A fully-featured DOS is required to run the game, because the game reads additional data from the disk. You can run the game directly from the FLOP reader or DOS, but not from QMEG or other simple binary loaders.
