Good morning fellow Rollers or anyone else that stumbles upon this post. I've been debating with myself if purchasing the Christmas Event pass. There are three options currently with 2 weeks left for this season:
1) Play free and earn some free rewards (i.e. simple miners - the best is the last one 'El Monstro' - 110,000 Gh/s or 110 Th/s
2) Pay the cost to upgrade - This will unlock premium rewards in which you still have to earn xp to unlock them.
3) Pay the cost to upgrade to premium season pass - this will unlock everything included in pass immediately and you don't need to earn xp.
Below is a picture of items that can be earned at various xp levels:

I started playing rollercoin at the beginning of the year, so the Christmas event had been out for a week or two already. However, I've noticed something since I started playing. The original price for the premium event pass started out at $399.99. That was too expensive for my taste at the time so figured I'd just grind away and get what free stuff I could getting xp.

Few weeks ago I noticed that the price wasn't the original $399.99. It had dropped and has been dropping. It currently costs $289.99.

That is a significant price drop. Turns out each time you gain XP and get to next level, it will take $10 RLT off. If you're like me and have been wanting it but just couldn't bring yourself to spending $400, it is now a much better price.
