So it is not a zero HE game. Real zero HE game would be without Zero/Monk
There will be no fun of the game if they remove the zero/monk payout from the roulette. The real zero HE game can also be with the special zero/monk payout. However, the HE is approximately 0.1% for their roulette game with MONK currency. Contribution to the expected return amount for 1 to 7, 8 to 14 and special monk/zero is respectively (7 ÷ 15) × 2.14, (7 ÷ 15) × 2.14 and (1 ÷ 15) × 15.
• Total expected return is: (7 ÷ 15) × 2.14 + (7 ÷ 15) × 2.14 + (1 ÷ 15) × 15 = 2.99733
• So, the HE is: [1 - (2.99733 ÷ 3)] × 100% = 0.089%
The HE is 6.67% for a bit lower payout of all outcomes in other crypto. @monkgg, The HE isn't really 0% in MONK token for the roulette game. Have I missed anything on the calculation?
To have 0 house edge on red/black, the multiplier would have to be 15/7, or 2.142857... which we truncate to 2.14 since it's an irrational number. Soon we'll increase the floating point precision of this value to make it closer to 0% house edge.
To have 0 house edge on green, the multiplier is 15/1 = 15x, which we don't have to truncate and therefore all green bets will have an exactly 0% house edge.
Thank you very much for taking the time to explain in more depth.
IMO it would be very easy and simple to take out the monk for a real zero HE roulette game for red and black bets.
Actually you can offer 2 games > the one without the monk and one with the monk.
