This calculator is a real surprise – since there is next to no information about it anywhere on the internet, I figured it to be another derivative of the CG-8 Reversi / Othello game.
Turns out that Go is an old old old game and other than the round counters, bears little resemblence to Reversi at all. Check out the Wikipedia article on Go.
It is also the only game calculator from Casio that is this particular shape (although there are plenty of non-game calcs in this style) – it has a rotating contrast control on the side of the calc.
I haven’t totally got to grips with the game, but fortunately it has a hint/solve function which makes it easier – the instruction manual would be nice though!
Rare as a rare thing, you won’t see many of these around. And if you are after a cerebral game, you can’t go past Go. They were playing it before Jesus was born so it must be good!
