Boss casino is one of my favorite casinos. I've claimed all of their bonuses by now and only a few days ago I claimed their Saturday bonus, again. They are a unique casino and every day a player can claim their daily bonus. On Saturdays for a deposit of 20€ or more, player gets 70% match bonus and from 10 to 40 free spins on one of the games. The match used to be 80% but now is lowered.
As all of their bonuses, they are very easy to claim and you do that in the cashier, when making a deposit. It was in the evening when I wanted to deposit, but when I visited the cashier, I had only welcome bonuses available (even though I had already claimed them both) and there was no sign of the Saturday bonus. So I went to their live chat and had a conversation, support offered me a bigger match bonus for bigger deposit, as I am a loyal player, but I didn't want to deposit 50€ in a single deposit, so I decided to go with the Saturday bonus. Since I was eligible for it, I made a 30€ deposit and live support added the match bonus manually.
So for 30€ deposit I received 21€ bonus, which carries 35x bonus wagering requirements. I personally find this a great offer, as the casino offers nice game selection from Microgaming, Netent and few other softwares. There are a few games that can't be played with bonus funds, so I would recommend to double check the bonus terms prior playing. Another part of this bonus is free spins that are given 24 hours after requesting them. I do find it a little unusual to ask live support for free spins that you should get anyways. They changed their terms not so long ago and before I wasn't eligible for the free spins but now I am, but unfortunately no one in the support told me that and there were few times when I didn't get the spins, just because I didn't ask, cause I thought I couldn't get them. Anyways, support tells you on which game you will get the spins and for a deposit of 20 you get from 10 free spins. Mine were given on Diamond Dogs slot and had no wagering, which is great.
So with 51€ balance I went to play Immortal Romance slot. I had many decent winnings, but none were actually above 100x bet so my balance was slowly decreasing as the time went by. When my balance got down to 15€ I decided to play Koi Princess. At first I had a few features one after another, and I managed to get 50x bet win, which was my best result on the game that session. I played for about an hour, my balance went up to 23€ but eventually I got more empty spins and lost all. The next day I went to live support to see when my free spins will be credited. I was told that the manager wasn't working the weekend and that I should come by the next day. I wasn't very happy about it, as I requested them in the live support, as it's written in the terms, so I wanted to get them in 24 hours not 48 hours, but at the end it was a free offer so I can't complain.
The next day I went to play my spins and they were in my account as promised and I won around 3€. With that I went to play Drive slot and ran out of balance ery quickly.
Overall I do like this bonus as it gives a good match bonus and you can claim it once a week, which is great. Wagering requirements are also very friendly and there's always live support to help you. I really hope that getting free spins will be smoother in the future, but otherwise, this is a bonus I rate with 9/10.
