As an example – for every $3.00 played on Major Millions, 10 cents goes into the progressive pool managed by Jackpot Madness.
You bear 2.5 cents if your aff percentage is 25% – the casino pays the rest.
Thus, if a player spins 100x at Major Millions, and breaks even, it means a net loss of $10 to the casino – and subsequently they deduct $2.50 from your earnings.
So you might see progressive deductions of a few thousand dollars – which is usually shown as the net deduction a casino has to pay for play on progressives – and naturally it will raise eyebrows.
But, in most cases, the deductions have resulted in a much larger increase in your income since most people don’t win playing progressive slots.
None of the casinos currently separate progressive play from other games – though I think it might be a good idea – then you would get the real picture as to whether progressives are making you money or not (and they should 95% of the time).
