I have already said we would take the player back. The account is open.
Unfortunately, the damage is done, and CANNOT simply be undone by reversing this decision.
I suspect that it is the PUBLIC DISCUSSION of this case, and the fact this was SLOTS play, and with NO BONUSES, that forced your hand. No amount of apologising will take away the fact that you made this decision in the first place, AND used the Vegas "card counting" argument to justify it, even though the games were SLOTS. There is STILL the risk that other slots players will be booted for being "too lucky".
In the bigger picture, this is just the kind of case that perpetuates the myth that "all online casino games are rigged, not random", and YEARS of assurances, third party TST testings of RNGs etc are flushed down the bog overnight by ONE careless, but OFFICIAL explanation from a casino operator.
This was tried before by Heroes Casino. Faced with paying out more than they could afford, they made one excuse after another, finally telling the player they cheated by "observing patterns", and being able to predict which cards the RNG would produce next, and betting accordingly. GaleWind, the software provider, would have none of it. They yanked Heroes' license, paid the player out of their own pockets, and THEN had to repair the damage because an OPERATOR had more or less admitted that the software was non-random, and could be beaten by observing patterns in past events.
The ONLY logical explanation for making such a decision in the first place is that you TRULY BELIEVED your SLOTS could be beaten by what you called a "sharp player", and were confident that said player would keep on beating the slots unless they were shown the exit. This itself can ONLY happen were your SLOTS RIGGED, and this "sharp player" had found the "pattern" that enabled them to outsmart the games. This would be the slots equivalent of the "card counter", and it IS true that a player who continually wins, AND is found to be "card counting", WILL most likely be asked to leave a Vegas casino (or told to play the slots instead
)
This tale will have other players running for the exit because such a decision implies the slots are NOT RANDOM, and LOSING players are therefore going to assume they have been cheated, rather than having lost due to "being unlucky".
Mathematically, the slots will return 97.5% back to the players as a group, so even if ONE player is "too lucky", this will be compensated for by players who are "unusually UNlucky", and don't even get their 97.5% RTP.
Long term, for EVERY $ bet, the casino will make 2.5c (assuming you are STILL on 97.5% as boasted in the past) - some individual players will win, some will lose. Booting out any individual player will MAKE NO DIFFERENCE to this, because there is a ZERO element of skill in slots. The ONLY way to play "sharp" is WITH bonuses, and is often the reason casinos drop bonus offers (players beat them to +EV).
