The problem I have with this analogy is that the local mini-market is providing a useful service to society, so someone might choose to pay slightly higher prices because they appreciate the convenience of a nearby store that provides them with a function that the nearest branch of Asda a few miles away can't.
Playing at an online casino is an entirely different scenario, the casino exists only to take money off the players, there are no goods or meaningful services for sale (and indeed the casino is basically just 'reselling' games made by other organisations), the players only play in the hope of winning, and to fulfil their desire/urge to have a gamble. (Or in some cases, because of addiction.)
Moreover, there's no such thing as 'bespoke service' at a casino these days, there's no kind of 'boutique offering' that smaller casinos can provide, since none of the games are their own and the bonus is all but dead (at least for 'normal' players), as such all it really comes down to is (1) How much are the games paying out, how likely am I to win (i.e. RTP) and (2) How quickly and with how little fuss will I get paid if I win? (3Dice is one of the very few (only?) exceptions left in this regard, as they're entirely a self-contained outfit, do make their own games, do maintain a bonus/VIP structure, do run special offers and promotions that actually have some value to them, and so on - if there are any others, I'm not aware of them.)
With the greatest of respect I honestly have no earthly idea why any player would bother with 99% of the new casinos that turn up, especially since it's the smaller operators that seem to struggle most with quick payouts, support and live support, SOW nonsense, not understanding the rules under which they're supposed to be operating, games being laggy and disconnecting due to shitty integration, and so on.
In a world when Unibet still exists (top RTPs on everything, massive selection of providers and games, payouts often in 5-10 minutes, easy document verification, no SOW crap etc), what on earth is Twin's pitch for our custom when they can't even satisfy the 'Unibet Standard', let alone when they've also decided to help themselves to a house edge of a truly monstrous 12.5% on PnG slots?
I can understand the case (although I personally disagree with it) for playing at somewhere like VS that do have a decent number of perks and rewards on offer, do pay out very quickly, and have at least only taken 94% versions of games rather than going any lower. (Although it can never be stated too many times
that a move from 96% to 94% increases the house edge by 50%.)
I've read the CM review for Twin and nothing jumps out at me as being exceptional, including the bonuses which are described as 'great', and all of this with the knowledge that they'll reduce RTPs on some games to 87.5% and not even tell their players about it, waiting instead to be called out on it here on the forums.
My recommendation would be to add RTP as a category here, weight it more than the other categories (so it has a 200%-300% weighted impact on the overall casino rating), and award Twin zero shields out of five. I'd also add an explicit 'LOW RTP WARNING' to the 'Cons' column.
