Mystery Box

Earn a box for checking in days in a row. Open it for XP, avatar frames, flair and key shards. Keyholders can seal a box with a reward of their own.

You earn a Mystery Box for checking in days in a row. Open boxes in Game Center → Mystery Box. They're cosmetic: nothing inside changes your lock.

Earning boxes

A day counts when you check in at least once that day, in your own calendar. Boxes come at:

every 3 days in a row: a Common box;
every 7: Uncommon;
every 14: Rare;
every 30: Epic;
every 100: Legendary.

On a day that hits more than one, you get the rarest. A check-in photo your keyholder rejects doesn't count toward your run. The page shows your run, your best, and when the next box comes.

Boxes wait until you open them. Having 5 unopened at once earns the Hoarder badge.

What's inside

Common: extra XP, or a key shard.
Uncommon: new flair to wear by your name, or key shards.
Rare: an ember piece. Three make the Ember frame.
Epic: the Obsidian frame.
Legendary: the Legendary frame and its badge.

Wrap Day: a check-in on Friday, November 27, 2026 gives a Holiday Box with winter flair you don't have yet (❄️🧣🧤☕⛄🎁⭐🎀) and 50 XP, plus the Holiday 2026 frame. See The Holiday Lock.

Every box also gives XP. Once you have a box's frame, the same kind of box gives key shards instead. Key shards earn the Key of Brass (5), Silver (15) and Gold (30) badges. Opening 10 boxes earns the Collector badge.

What's inside is settled the moment you open it, and the box keeps it: opening it again shows the same thing.

Opening a Rare box: an ember piece toward the Ember frame

Wear frames and flair

Under Your collection, tap a frame or a flair to wear it. Everyone sees it on your avatar and next to your name. Tap None to take it off.

For keyholders: seal a box

You can put a reward of your own in the next box the person you hold the keys for earns:

Open Game Center → Mystery Box (or Seal their next Mystery Box on the Warden tab).
Under Seal a box, write the reward and tap Seal it.

Your reward replaces what's inside their next box, which still gives XP. Up to 3 can wait, and you can take one back before it's used. You get an alert when they open it. Only their current keyholder's seals count.
