Actually I was so shocked to see my balance increased so fast, last time I checked it was around 1mbtc (6 from lucky dice roll and others from referral earning) but it was increased to 0.01xxbtc after few hours from my last claim.
Accidentally I clicked withdraw button and it was direct withdrawal without any other options to set my withdrawal amount or anything else.
I reveived my withdrawal after some hours, but I'm still little bit curious how my balance increased significantly as my referral earning is only around 45k satoshi while I only claim the free roll lucky dice less than 10x.

Yap just noticed it as well and mine is 660minutes left to claim the free roll. Seems that they increase the time limit to 12-24hours per claim.
