This is the only game in the series that uses SCREEN 1 mode. I do not remember why this mode was chosen for this game.

I do not remember much about this puzzle. The only reason it was written is that almost a month has passed since SNAKE.NSG and I still had not come up with a new game. So I decided to sit down and write at least something. This is that "something".

This puzzle was invented by Sam Loyd in 1870s. It is said to became an instant success. I guess, people back then were more easily amused then sophisticated folks of today.
