some app in moneypot have very low house edge, i've seen .1% HE and .2% HE in dice game, i just forgot what are those app names but you can search for it but for other games such as rollette and slots, most casinos have the same HE
JUst for info this new Moneypot app has 0.01% HE
https://www.moneypot.com/apps/1429-xchange-anything-dicei am not really sure about that new app, i visited the app and check it but i saw 49% win chance on 2x multiplier so it means 2% house edge but when i check my bet id on moneypot it shows .01% house edge
Formula for House Edge percentage is HE = 100 * (wager - EV) / wager
Generally, rounding is not advantageous to casinos, so while calculating payouts, truncate or floor or rounddown functions are used to bring down payouts to minimum payable units for that casino (for moneypot, minimum payable unit is satoshi). In other words even if payout is x.99 satoshi, actual payout will be x satoshi and left-over 0.99 satoshi will contribute to variations shown in HE on bet details page.
You will see maximum variations in HE for small and petty wager like few satoshis. I think, (I can not confirm as I do not have access to mp code), HE shown on bet details page of moneypot is calculated on actual amount or figure that mp gets as HE for that particular bet.
So actual House Edge at 1% HE for 1 satoshi wager is 0.01 satoshi, right? And that is why HE shown on moneypot bet details for 1 satoshi wager is 0.01% makes sense?
Yes, effective HE in my game is 2%. I say effective for practical purposes as actual HE set in game is 1% and remaining 1% of wager is passed on to fund jackpot. Effective HE of 2% remains fixed for all the be sizes and all the chances or all the multipliers.
Please let me know if it is still unclear or you need more info.
Good Luck!!
