http://play.luckco.in/ offers the same paytable on jacks or better but with a progressive jackpot. That makes their odds slightly better than yours. Currently betting 0.005 and hitting a royal flush pays a little over 5 BTC which is a bit silly because it makes the RTP bigger than 100%.
On the other hand their game keeps going down due to programming errors, isn't provably fair, doesn't feel anywhere near as slick at bitzino, and is pretty slow.
Our Jacks or Better pay table is a standard "Full Pay" pay table, which offers 99.54% RTP under optimal play. The games where we made tweaks were Double Bonus Poker and Double Double Bonus Poker, where we increased the payout of Straight Flushes up to 60 for 1, and also increased the payout of "4 Aces with a 2-4" up to 460 (instead of the standard 400 for 1). These adjustments bring these pay table's RTP above 99% (to 99.48% and 99.46%, respectively).
We have taken great care to ensure our risk of ruin is minimal. As the player's edge increases, the risk of ruin for the house increases (when it's >= 100%, the risk of ruin for the house is guaranteed in the long run). So, in games where the RTP is above 100%, the player may think they're getting a good game, but in reality they're betting against the house going broke.
The "more pay tables" element at bitzino looks like it will just expand that section of the gui, but it in fact opens a "modal" dialog. While it's open I'm unable to edit my bet or start a new hand. This would be clearer if opening the 'more pay tables' thing greyed out the rest of the interface, in the same way that being half-way through a hand greys out the "more pay tables" element.
Good call! We have changed the UI so that there is a translucent overlay over the rest of the UI, so that it's more obvious that this is a modal box.
Finally, I wonder if it would be worth making the 'held' marking less subtle. I just played a bunch of hands, was dealt 2 pair, quickly clicked on the 4 cards I wanted to hold and clicked 'draw'. It only held 3 of the cards, so I guess one of my clicks missed, but I didn't notice. I think the little grey shadow that appears when I hover looks similar enough to the black 'held' that appears when I actually click that I was able to miss that fact that I had mis-clicked.
We took your advice and made the UI slightly less subtle - we added a few pixels to the height of the 'Held' marker, and removed a few pixels from the grey shadow which appears on mouseover. We didn't want to change things too much, but hopefully the small changes help to make a larger differentiation between the two, and makes it clear which cards are held.
How about introducing a no zero roulette? Have a 0.1 BTC max bet and a 0.01 BTC min bet. You would still make money over the long run as you introduce people to bitzino, and a lot of people tend to keep gambling till they lose them all.
We have been considering doing something like this on a short-term basis in order to get users to try us out. However, we likely won't be offering anything like this on a permanent basis. Even at small limits, zero house edge games make the risk of ruin for the house guaranteed over a long enough timeframe (unless the games are Player vs Player, which is something we're planning on building).
