I remembered playing at Rival casinos last year, I wouldnt take bonus if playthru is over 30x.  There were good bonuses back then, cashable, low playthru,....  Nowaday the bonuses are crazy at these Rival casinos with playthru set up high in the moutain, lol.  Example, Vegas Regal has 500% bonus with 50x playthru and 2x max  the bonus cash out.  Bonus rocket level 1,2 and 3 with 100%, 200% and 300% accordingly, with 40x, 90x and 140x in playthru.  Yes, I'm not kidding, lol, 140x in playthru at vegas regal.  Can you beat it? haha.
I saw 400% bonus with 55x in playthru at Tropica casino.  300% with 45x playthru at orangegamez.  I know myself that I dont want to take small % bonus with low playthru because my balance will be gone in 5 min.  I'm planning to deposit with rival casinos, but good bonuses are hard to find.

Supreme play and 21 grand usually have reasonable playthrough amounts without the max cashout.  Though they do only allow $1000 a week i believe.  Really the only 2 rivals I play anymore.
