I think DomainsRate feels its a good typo because, and feel free to correct me if im wrong, "casino" sounds like it may be spelled "caseno", and therefore the "e" and "i" being nowhere near each other on the keyboard is of little significance
i think the typo can be decent once that site is developed, which it most likely will be since someone paid such a hefty sum for the name
and obviously, the good thing about casino/poker typos is that they dont need much traffic at all because the CPC is so high
best of luck to ya !
