Cancel the bonus after a bet? You would like us to remove the bonus from any player who violates the terms? That's less fair than the current system IMO.
Explain fully how you would like it to work and I will genuinely consider it, if it's a fairer system and workable (bearing in mind we'd need NetEnt's help too) then we'll implement it. Always open to suggestions for improvement.
Also, if the CAG here think that it's a predatory term then it goes, I can't say fairer than that.
If anything needs working on, it would be a system that blocks players from placing a bet that is outside the rules. For example, they press "spin", and instead of spinning, they get a pop-up saying that their bet exceeds the max allowed, and to please adjust the stake to xx per line, xx per spin.
This would be fairer than removing the bonus or locking the account. It is something that all software providers should look into. Microgaming already has such a system in place, but it works only on coin size, so it is not foolproof. I have seen it running at GoWild. When I had a bonus, the most I could bet on Munchkins went right down to around £11, but with no bonus, the usual max bet of £75 could be selected.
Developing, and the making live, an upgrade in an hour is a recipe for disaster. Changes need to be tested thoroughly to make sure the fix actually works as intended, and also does not break something else. The more robust the implementation, the longer it will take.
For now, we have to rely on a fair interpretation of the rule on a case by case basis, like we get at
32Red, and clearly are going to get at Redbet too.
The rules in place used to be a vague "large bets consisting of the majority of the bonus balance", but it was discussed in the forum, and the consensus was that a fixed figure based either on an absolute, or percentage of the original bonus, should be used.
Accredited casinos tend to use one of these systems. Some are max bet of xx% of the bonus credited, whilst others specify a max bet amount, such as 6.25 at 32Red, and 5 at Redbet. Redbet have also added a line max, which many may view as an additional complication of what started as a simple rule.
A few casinos actually take the opposite view, specifying a MINIMUM bet. Ladbrokes, for example, specified a MIN bet of £10 at Blackjack if playing with a bonus. Lesser bets didn't count as they were seen as "grinding out the WR". Many also list excluded games when a bonus is used.
