Are There Leaderboard Rewards?
In Main Events (the long ones that last several days) you can earn new Characters, Cards, Nanospiders and Stubs for Repeaters. There aren't any rewards for Mini Event Leaderboards - yet!

Who Are These Players?
Your Leaderboard is a group of 200 players across the globe! The Character names beside each player are randomly chosen from the game. There are also only human players, no bots!

Your list will likely be different than your friends' Leaderboard since a Leaderboard fills up with 200 players pretty quickly, necessitating a new one being created.

What Do Those Numbers Beside the Names Mean?
They represent a player’s User ID which can be handy if we need to quickly check a fellow player on your Leaderboard. Speaking of which, if a player suddenly rocketed to the top, it’s possible they got there by making a crucial upgrade, splurging on Dream Crystals, using a Time Skip or making a purchase.

We’re always watching for cheaters so play nice!
