They need to lose the 80% bullshite
80% reflects the overheads of siting and running Fruit Machines in their physical form. There should be no need for this tight payout online.
The standard for online slots is 95%, and unless they are giving away bonuses, they should stick to it. The new breed of UK "fruit machines" with 500 jackpots are set to 92% (some are 90%) - they need to bear this in mind.
IF they are using the original ROMs to power the game, there MAY be instances with early machines where they simply cannot set them as high as 92%.
Free play should give some idea as to how they MIGHT play for real money.
Once they are offering real money play (seems to be in 85 days), we have to ask who licenses and regulates them, and who is backing them. To reproduce original machines online, they will need the agreement of the patent holders for the original games, most of which are now owned by Barcrest, who themselves are running an online casino (Kerching).
I doubt it can beat the scenery when travelling though, unless they can reproduce a virtual arcade (or virtual service station) to walk into.
