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:

If you do play good luck!
