As I have pointed out our rule is not unfair or uncommon, it's just a rule. There are many ways that you can restrict the maximum bets, but even those that are based on starting bonus, or only bonus or starting balance or balance are a just as impractical and affect the entertainment aspect of the games, that is, unless the operator creates a system to monitor these limits as zanzibar suggests. We will implement a system that is capable of doing this in the short term. In the meantime we don't expect casual players to worry about this and we won't penalize bets under €50, we have never done this in fact.
Our rule is not a pick-and-choose rule, we apply it consistently, if we allow big bets with big bonuses, then we have to make sure the rules are followed. We don't have a problem with winners, we want winners, but we have a problem with rules being disregarded, just like any other operator. Had the OP bet £200 and hit big on the first spin, it would have been another story, but this is not what happened.
We value the feedback that we have received from the community. As you can see I have been trying to answer all the questions, we take these matters seriously and it is very important for us to come to settlement with the player.
Rules are not just rules in the real world. Some are OK, others are deemed unfair both by the average person and by the legal system.
There are many ways to restrict the maximum bet, so why did you choose the worst one of all for the average player to monitor and implement during their play.
Rules that arrive at a fixed max bet for a given initial starting balance are far more practical than any other. The player has just a single number to remember throughout their play, yet by using a percentage it allows the max bet to be set in proportion to the amount deposited, so high rollers are not held back by a rule designed to cater for those who make smaller deposits, and those who make smaller deposits can't bet the full amount in one go.
It can't be getting applied consistently as it has not been seen to be applied as written, which would include those cases where players bet 60c from their last €1 balance. It's ONLY seen to be getting applied for players who make very big bets from relatively high deposits.
You now admit to be operating a new set of rules that you are refusing to publish until this case is resolved. This is inherently unfair as the published rules are now wrong, yet it's all players have to go on. There is no need to delay updating the rules as this case is about what happened last year, not what is happening now. The only reason for delay would seem to be that there is an intent to renege on the promises to update the rules should this PAB go in your favour.
The old rules, incidentally, are an advantage players' paradise if played properly, and not how this player did. Rather than flat betting at around €200, each bet would be made at the exact max allowed, or as close as possible to it whilst being below it as possible. This would result in a form of "reverse modified Martingale" where the bet was increased after a win, and decreased after a loss. This would take full advantage of the overly generous rule in it's original form, and by the laws of probability you will get a small number of runaway victories for players who end up being allowed to make truly HUGE bets after a big win that will outweigh the money made from those that bust out.
If these logs ever end up being revealed here, it would be interesting to see what the outcome would have been had the player been smart enough to adjust the bet after each spin to the max possible allowed by the rules, and what they could have walked away with without breaking any rules, assuming a withdrawal was made as soon as WR was completed.
