I guess there is a fixed amount for the recent gameplay bonus, I received $41 for the recent gameplay bonus when I upgraded to Platinum II last year. I did not expect anything for the recent gameplay bonus since I did not wager much before reaching my Platinum II (maybe around $75k only in a month to level up). Just take it as an additional bonus and I think it is more than enough since we may not get the same in other casino. There is also reload bonus that we can claim which is actually more than the recent gameplay bonus but we need to claim it everyday.
