The money was credited right away and there I got a little disappointed. For some reason I thought that the 4th bonus was a 100% match, but I was wrong and for players' fourth deposit, there is a 50% match bonus. It was obviously my mistake, but anyways, for my 50€ deposit I was given 25€ bonus and with 75€ balance in total, I had to wager 1000€.
There are a few games that can't be played with bonus so I would recommend to double check terms before playing. None of my favorite games were on that list so I was good to go. I started to play Immortal Romance with minimum bets. It took me only a few spins to trigger free spins feature. I had one big win in it and my balance was over 100€, so it seemed like a really good start. And again I was wrong.
After that I had many free spins features but none paid over 50x bet size and at some point my game turned into a dry run and I was loosing my money rapidly. When I had around 30€ left, I decided to try Twin Spin, hoping for some miracle to come my way.
I was playing with minimum bets only and I had a decent run for some time, even one 100x bet win came, but I couldn't reach over 50€ balance. I was low rolling for about an hour but my luck went away and I lost all balance eventually.
Overall I recommend Oshi casino and this particular bonus as well, it has a good match amount, friendly wagering and lots of games to play with it, so I wasn't disappointed.
