The question is whether the max bet rule applies to initial single bet or total bet. For example: with a 100€ bonus, am I allowed to put an 29€ initial bet on a hand of Texas Holdem bonus, where the final bet size is typically 5 times ante = 145€.
Assume it is TOTAL bet, unless CLEARLY told otherwise. You will ALWAYS be betting the full "play bet" on a good hand, so it is a good assumption to make. Blackjack is a little different, in that splits are considered as two separate bets from that point on. Splitting is NOT something that is done as standard when playing Blackjack, so operators that have expressed a view will allow the initial bet on a DEALER hand of Blackjack to be the one that determines violations of this rule. They also make it clear that in multiple hand versions, your single bet is the sum of the bets on all positions played. This closes a loophole where players bet 30% (for example) of the bonus balance per position in the hope that the dealer would bust, and effectively allow the "all on Black" advantage play method in through the back door by the exploitation of this potential loophole.
The ONLY loophole in slots is the "double up" gamble game after a win, and many terms ban this as a means of doubling up a big win from a slot bonus round, or even a decent line win. I usually steer clear of this "double up" game anyway, and especially so with a bonus.
The problem is that players always have to "watch their backs" when playing at any casino, as they will not TELL you that you are walking into a trap, they will let you do it, even WATCH you do it in some cases, and then spring the violations trap when you withdraw. If you "watch your back", you will have checked out the scene before hand, and thus would know where these traps were, and would steer clear of them when playing.
The ONLY casino that has ever confiscated my win was Crystal Palace, and it was from a free chip, and my suggestion as to what Mr Curran could do with it was just as colourful as how he dealt with players who complained about getting screwed over.
Prime Casino tried to find a problem with a £500 withdrawal, but after I made it clear I knew the correct procedure, they decided to quit the fun & games, and paid up within the 14 days suggested by eCogra before a formal complaint could be lodged. I won this £500 on SLOTS, and it was from £35 or so of comps. Having READ THE TERMS, I knew from the outset that "they didn't have a leg to stand on" if they were trying to sniff out a violation. Lucky they didn't try this on the £6000+ I won off them a couple of weeks before. All they achieved was to ensure they would not get the chance to win it back.
