I have decided to pay 4500 reward points for 5WOF spins per free roll and I managed to collect 95 WOF spins. And I am glad I did it! My result is better than the one from

I get my Reward Points back + BTC + lottery tickets...

Wow, those are some impressive results. I tried this once with a shorter RP amount. I bought 1 WOF spin/roll for 900 RP.
But I kept forgetting to click on the roll after every hour and that's why I managed to collect only 6 WOF spins.
I hardly got 90 RP and some lottery tickets from those spins. It was a bad experience because I lost 900 RP.
But at the same time I accept that it was my mistake. I should have done more rolls. At least 10-12 rolls would have given me a good chance I think.
