What's Keno? It's similar to a lottery. You pick the numbers you think will be drawn, and win if you guess them correctly. The amount of money that you win is determined by the amount of numbers that you correctly guess.
In each session, 10 numbers are drawn from a total of 42 (the meaning of life?). In any single bet, you can choose anywhere between 1 numbers and 10 numbers. The more numbers you choose that match, the higher the possible winnings.
Number choices: 1 - 10. Risk payouts: Low - Medium. Max profit: 2 BTC. Min bet: 0.00000100 BTC.
