Are you Keno to do some more gambling?

So Keno is kind of a boring game, but at least it’s easy and quick to play. The idea is simple, you pick between 1 and 10 numbers and then Torn draws 10 numbers randomly.

If your numbers match the drawn numbers you can win a prize (if you choose more than 7 numbers you need two matches to win a prize)

Now the odds of this game aren’t good, and they don’t change (unlike blackjack, hi-lo and poker). Here is a table of expected returns:

Picks Return per 1 bet
1 1
2 0.984177215
3 0.973101266
4 0.991303001
5 0.991319016
6 0.99760486
7 0.984712671
8 0.994884466
9 0.995126594
10 0.988061744

As you can see there is no correlation between how many numbers you pick and the odds of winning. The best ‘loss’ is the 6 picks, as you only lose 0.0024 of your stake. But of course your max win is only 4b.

Personally if I have no time to do slots or blackjack I play Keno with 10 numbers – As the prize and odds of the top prize are the best, even though in the long run I lose more than 9 numbers. The trick here is to win the jackpot before you’ve played 10b worth of games.

Here is the winnings table:

Picks/Matches 1 2 3 4 5 6 7 8 9 10
1 8
2 2 38
3 2 7 80
4 2 3 10 300
5 1.5 3 5 50 2b
6 1.5 2 4 10 200 4b
7 0 3 10 25 150 1000 5b
8 0 2 7 20 200 500 1b 10b
9 0 2 5 10 70 200 1b 10b 10b
10 0 1.5 3 10 50 500 5b 10b 10b 10b

If you do play good luck!
