There are people that can't afford £1 scratchcards, yet still prioritize them over other things. So 'affordability' is relative.
One would imagine then, that a governing body took an 'overview' of these and either capped their usage per user, or gave casinos the autonomy to implement them on a per-player basis. God knows they've set vague guidelines on just about everything else for casinos to dance around, so why not this.
Yet of course not - far easier to just ban them outright and ostracize a subset of gamblers that did enjoy BBs and were in control of their application, because then you can call that 'player protection' and bask in your steadfast dedication to tackling problem gambling.
Again, as with everything, the initial idea of Bonus Buys was fine - yet before long, became subverted by designers' greed and ever-ludicrous outlays. Because why not? Designers are going to push boundaries if unchecked, but just like with everything else, flipping lootboxes, gas companies, retailers that hike prices up because they can
, the same was always going to apply with Bonus Buys.
Why 'regulate' them when banning them is just easier?
I don't accept that reeling off a succession of £10 BBs - all perfectly within my allocated budget for that session, as opposed to grinding menial 3p wins on White Rabbit for three hours with a slew of shite Bonus teases
- makes my playstyle 'problematic' or worthy of prohibition. I'd even argue that it reduced my overall gambling time and focus, not to mention eagerness and anxiety of where the next possible win might come from (i.e hours of frustrating spinning, busting, then re-depositing to achieve a sense of 'recompense' for that shite Stuka-bomber session of bewildering nothingness).
At least with Bonus Buys I get to the brass tacks on my terms, within say a £50 budget, play the only part of the slot that's actually worthwhile, while enjoying the spectacle of the best the game has to offer.
There is nothing wrong with BBs, there never was anything wrong with BBs, yet short of regulating them, they've warped into an unsavoury and cynical cash-grab, with many games designed around this blueprint. All pretty sad, and as ever, could have been handled much better.
But why do that?
