Safety Net:  This is a new type of bonus which only started appearing in 2014. When you play, your deposit is used
first, and if you don't lose all of your deposit and start using the Bonus chips, then you can cash-out
your deposit and winning at ANY time (e.g. after a big win). 
If you DO start using the bonus chips, then you must complete the WR before the bonus and any winnings
from them are converted into real money which you can cash-out.
(Note: Your wagering wth your deposited funds DOES count toward the total WR at some casinos)
Because this bonus is VERY good for the player, the WR rating above is increased by +1.
Post Wager;  The bonus is added to your account AFTER you finish the WR with your own funds. Then withdrawable.
Pre-Post;  Bonus added to account after half wagering done, then you must do the other half to withdraw.

How the Bonus Rating is worked out using two factors:
1. (Bonus - (WRx5%))/Deposit = Expected return on your bonus after completing WR, based on 5% house edge slots.
This returns a figure from +1 to -4 (e.g. -2 would mean you would lose twice your deposit by the time you complete WR)
(Note that for phantom bonuses the bonus is deducted off the expected return figure).
SpaceRCname94,SpaceRCname94
2. WR/B/% = Value of the bonus as a factor of how big the WR is & how big the bonus % is.
Figure = 0 to 200. Lower is better.  (e.g. A 200% bonus with a WR of Bx30 would give a figure of 15.)
To make this compatible with the (1) it is divided by 100 for the final calculation:-
Because (1) is usually negative, we 5 add to make most of the ratings positive, then deduct the value defined in (2)
Examples:-
Ladbrokes 1 (Bonus 100 - ((WR 800x5%)=40) = 60 of your bonus left after WR.
(100%, WR Bx8) Return = 60 / deposit 100 = 0.60
2 (WR 800/bonus 100) = 8  Divide that by Bonus 100% = 8.
Divide by 100 to make compatible with (1); 8/100 = 0.08
Rating = 5 + 0.6 - 0.08 = 5.52
River Belle 1 Bonus 75 - ((WR 2250x5%)=113) = -38 of your bonus left after WR.
(100%, WR Bx30) i.e. You would lose all your deposit & 38 of the bonus by end of WR.
Return = -38 / deposit 75 = -0.50
2 (WR 2250/bonus 75) = 30.  Divide that by Bonus 200% = 15.
Divide by 100 to make compatible with (1); 15/100 = 0.15
Rating = 5 + (-0.50) - 0.15 = 4.35
Note: Please do not read too much into the ratings - this is just a way of comparing the bonuses at face value.
Slots by their very nature are high variance and success with them is far more to do with luck & playing strategies
than the size or value of the bonus you start off with.   Please see the main site for strategies, hints & tips!
