This game was entered in the very first IFComp in 1995. The competition was originally intended to give sample code for Inform authors. This game uses the z-machine to model games like tic tac toe, dots and boxes, towers of hanoi, etc. using ASCII graphics.
The puzzles are unfair, and you must cheat to beat about half of them.
The game is full of homages to Curses! and Trinity. Several puzzles require explicit knowledge of these two games. Even with this knowledge, some steps near the end are extremely difficult to guess.
This game is interesting as a sample game and for fans of puzzles as described above.
