How do you play?
One simple rule: brush for 2 minutes, and Dim earns gems and experience. Everything else follows from that.
The timer
120 seconds, the length dentists recommend. A “3, 2, 1” countdown, then the brush starts scrubbing away on Dim.

Gems & levels
per completed brush
To spend in the shop. Every new buddy starts with 30 gems in their pocket.
per brush
One level every 4 brushes. The medallion on the home screen shows the level and the experience bar.
no cap
Morning, night, after a snack: every brush counts. Twice a day is still the recommended routine.
The belts
Only the judo kimono carries the belt that grows with you. It changes colour every 3 levels, just like in judo. An earned belt stays wearable: pick your favourite on the kimono card.

And they say a grandmaster belt is hidden somewhere… up to you to find it.
Dim’s feelings
A row of buttons sits under Dim: one tap and his face changes. Free, unlimited, and a handy way to say how you feel before bed.
- Happy
- Sad
- Angry
- Calm
- Scared

Shop & things
83 things, from 20 to 500 gems, across four rarities: Common, Rare, Epic, Legendary. One slot per category: one cap at a time, one buddy, one background.
- A full outfit (ninja, samurai) replaces the accessories being worn.
- Backgrounds and buddies are not worn: they change the scene around Dim.
- Every item can be previewed on Dim before you buy.
- There is a secret item. Shhh.
The profiles
Up to 5 buddies on one device, one per child. Each has their own name, gems, things and belt. Switch player from the avatar at the top of the home screen.
Everything stays on the device: no account, no sync, nothing to set up.
The screens

Home
Dim in his scene, the level medallion, the experience bar, the gems and the big “Brush my teeth” button.

Brushing
The countdown, the 4-segment bar, Dim brushing his teeth… and the “Well done!” with its burst of gems.

Shop
The catalogue by category, the rarity of every item, and a preview on Dim before you buy.

My journey
The ladder of belts, your current level, and how many brushes are left before the next one.
