Resets at midnight UTC. The same fresh puzzle drops for every player at the same moment — wherever in the world they are.

THE RITUAL

A daily puzzle is the smallest commitment that builds a real habit. You don't have to feel like solving — you just have to show up. Over weeks, that consistency beats picking up the app only when you remember. How to get better at number puzzles →

In the app, each daily solve extends your streak. Seven days: you earn a streak freeze. Thirty: a cosmetic. The ghost watches the count.

WHAT THE STREAK EARNS

DAY 7

Freeze + ghost hat

One free pass on a missed day. Your ghost earns the Dedicated hat — seven days is where the habit starts.

DAY 14

Devoted halo + freeze

A second streak freeze and the Devoted halo cosmetic. Two weeks without missing a single midnight.

DAY 30

Ghost face cosmetic

Your ghost earns the Relentless face. A month of midnights, and the streak remembers every one.

DAY 100

Immortal aura

One hundred consecutive days. Your ghost earns the rarest aura in the app — the Immortal.
