I can see why OLG is getting such bad reviews. Up until a little more than a month ago, I would've disagreed, but they have set everything so you don't really win.
I've played on this site for YEARS. I do both free play and with real money. The free play has always been the same win ratio as real play, and that still holds true.
I used to win a decent amount. Won the light trap jackpot on Larry's Lobstermania 2 several times. Also had decent wins on Cleopatra Gold and the Cleopatra Jackpot game.
I most certainly do NOT expect to win every time, but I noted about a month ago, that ever single time I play I lose..and very quickly. They've done something to the machines to set them not to win. On my three favourite games I mentioned above, the same thing happens every time. They make you lose at least $100 and during that time, you might win .80 - $2.00 and that's with making a $5 bet. Ridiculous!
The Cleopatra Gold game has this strip that says the game's name and if you get it on two or less reels, it might pop up to fill the board and then Cleopatra spins for you. This used to happen pretty frequently, but now, you have to lose $70 min before that bar will stretch up and give you the bonus.
They have definitely set their machines not to pay out. If you're VERY lucky, you might win back to what you started with.
I refuse to deposit there until they go back to being at least as honest as they were before. I've been playing free a few times a week to see if anything has changed, but it is always the same. Free spins have become non-exixstent. So has Lobstermania bonus with the three lobsters. I used to get free spins pretty frequently on the Cleopatra Jackpot game, but they hardly ever happen there either.
I won't be playing again. The are the greediest casino with the lowest payout ratio I've ever seen. There are plenty of other great casinos that have a fair win rate. Jackpot City is now my go to.
