Grarrl Keno is a game based on luck; there is only one factor in the game you can change: the numbers of eggs you bet on. Using the mathematical formula below I calculated the average NP you get back.
E= number of eggs you selected
H= number of eggs you selected that hatched
(E nCr H)+((80-E) nCr (10-H))
________________________ (divided by)
80 nCr 10
===================== (equals)
(= 1646492110000)
E | Average NP |
2 | 0.1820*bet |
3 | 0.07485*bet |
4 | 0.04016*bet |
5 | 0.0217*bet |
6 | 0.004623*bet |
7 | 0.001998*bet |
8 | 0.0000503*bet |
9 | 0.2805*bet |
10 | 0.2411*bet |
This proves you can’t really make a lot of NP (unless you’re really lucky; the chance of 30000 times your bet is far less than one in a million(1/8234055100 to be precise)). You should only play this game to get a trophy. When you do play, select 9 eggs. – Allergoeiste
