What is the house edge for the live poker? I notice before any cards are dealt, you offer 5.20 odds out of 6 hands which I assume means a payout rate of 86.66%, a house edge of 13+%?
Also, what happens when two hands tie for the best hand?
The calculation you provided is a bit incorrect, due not counting possible splits. This means you always get lower odds due to split calculation and on tie you get payout according to you bet / odd. In that case house edge is:
5% for lotteries and Dice
8% for poker (except starting odds)
In that fact making a bet on pre-flop is less profitable than after dealer shows 3 first cards.
Nothing changes on tie with two best hands - you get what you should get on this odd, due to splits are evaluated while calculating odds.
