Keno

Keno is a lottery-style draw game and one of the oldest formats in any casino. You mark a set of numbers on a ticket from a pool of 80, the game draws 20, and you are paid according to how many of your picks come up.

It suits crypto play for a simple reason: a round takes seconds, there is nothing to learn, and the outcome is a single draw rather than a sequence of decisions. That also makes it easy to play far more rounds per hour than you intended, which is worth knowing before you start.

The thing to check is the paytable, because it is where keno games differ most. Two titles with the same rules can pay very differently for the same number of hits, and the return depends heavily on how many numbers you pick per ticket. If a studio publishes an RTP figure, read it next to the paytable rather than on its own. Keno is often grouped with lottery and bingo titles, and the same advice applies to all three.
