Now the eagle-eyed of you may notice a cart variant here, hence there are two on this page. Not quite got to the bottom of it, maybe it was just a typo...making this interesting? whether this adds to any form of value hasn't really been established, in facet how many even know? till now. But you will see that there is a cart whose title is spelt "Billards!" rather than the correct USE/English word "Billiards". The only other two places that use the Magnavox style cart that I know of are Japan and Brazil. It's not the Brazil cart as that's called "Bilhar" and says "odyssey" not "odyssey2" on their labels as the "Odyssey" one if you like was never released in Brazil. It's just a typo as far as I can tell. later corrected...so an oddity to look out for.
PLAYINGA very popular game that world surprisingly well for the console considering the complexities of calculations. two-player game, the winner being the one who pots the black ball at the end of the sequence.
