The online version of keno is the same in most cases as what you would find in a local casino. There is versions of keno games that are different where you might win spins or have multipliers but online they are basically the traditional games which only have the numbers with no sort of bonuses. I have found that casinos which operate under the real time gaming software have the best payout percentages on keno. This is not saying keno pays out well overall as it really is one of the lowest paying game in all casinos where online or offline. Once in awhile you might hit good but most players will loose on this game the only attractive feature is it lets you play for a long time.
