I joined the game early on but didn't really play seriously until the last PeroPero Gambit in October. I struggled to get the 60th floor and I don't think I made it much further.
This time around I'm already at floor 100. I took it easy the past few days and mostly having a heck of a time the last two because of bad luck picking the right box (no glasses).

However, my goal was to get 50,000 stamps for the card. But I've barely cleared 5,000. Not sure what the trick is.
The last event we had was a blast. Really hope I can get that card later since I doubt I will make it during the event
