This 50% bonus is possible to get every Friday at omni casino, you just need login, make deposit, and bonus will be credited. As I told, this bonus available for you every Sunday, and of course this is not all from omni, you usually will get other bonuses. This 50% bonus have 15 x deposit + bonus wagering requirements, and it is cashable one. So it is just good average bonus which can give you some more chances to win in case you feel boring at Sunday.
I take this bonus few times from omni casinos, but usually I am not gamble at Sunday, at Sundays I am taking rest, drink beer, relax, and watch some movies or go outside, I really not like to spend this day for online casino. I can not remember any good session with this bonus, if only once I played during tournament, and was able to get nice play time and make a lot of spins. Next day I was able to hit some low tournament position, but it was something like lucky place, and I get 25$ free cash on my account, which I lost of course, but I really like such things. Also first place in this tournament is a lot of money, but you need to make a lot of spins, something like 100.000 spins I think.
Good typical bonus, without any extra, but still nice because it is reload bonus and you can get it every week.
