A small library, made slowly
Honest games for curious kids.
Cairn makes learning games for kids ages 3 to 6. No ads, no subscriptions, nothing collected about your child. Buy a game once and it is yours, even on a plane with no wifi.

Every game has to clear all six before it ships.
Little kids cannot tell an ad from a game, so our games have none. No banners, no videos, no "watch this to win a prize."
No accounts, no sign-ups. Progress, photos, and recordings stay on your device. We never see them, and we could not if we tried.
One small price, one time. No subscription, no surprise charges, no locked levels. Updates are free.
Each game follows what reading and child-development researchers have shown works, and comes with a plain-English note that lists the sources.
No flashing lights, no nonstop rewards, no tricks to keep kids hooked. A child can put it down without a meltdown.
After the first open, no wifi needed. Road trips, waiting rooms, the grandparents' house.
You went looking for something good for your kid and came back uneasy. Here is the difference, said plainly.
Each game builds one real skill, broken down by age 3 to 6. Roll over any game for the short version, the game, the science, the result. Click through for the full science and a guide you can use at home.
Letter sounds to first sentences, taught in the order the research actually recommends.

Remember-and-find games that gently stretch how much a little mind can hold at once.
Fair warning: kids beat grown-ups at this.

What comes next? Finishing patterns is how a child first learns to think in steps.
The “I got it” face is the whole point.

Look at the shape, then build it. Blocks, in your hands and on the screen.
Knocking the tower down counts as winning.
Spatial skill predicts engineering degrees. It also just feels great to build a tower. Both are true.

New words and how they fit together, for the talkers at the older end of the band.
Tiny humans, enormous words.
A child can decode every word on a page and understand none of it. Vocabulary is the half nobody gamifies. We will.

They always direct their own ending.
Comprehension is the whole point of reading, and it is the part most apps quietly skip. We start it before letters.

Naming big feelings and learning to ride them out. The skill no other kids' game is racing to teach.
A game that helps the meltdown pass.
Every other app is engineered to make your child harder to put down. This one is built to help them settle. Read that twice.
Read the science →I'm Ryan King. I help CIOs and technology leaders design AI systems and workflows, so I know exactly how modern software is built to capture and hold attention. Then I watched the same tactics meant for adults get aimed at my two boys, dressed up as a cartoon. That is the thing I could not let stand.
Cairn is the shelf of games I wished someone had handed me in the first place.
The thinking behind what we ship, written plainly, with sources.

A reframe parents can use, with the research that actually justifies it.
What an honest privacy posture looks like when the user is a four-year-old.
We build the library one game at a time and ship a game only when it clears all six promises. Tell us where to send a note when the next one is ready.
Send us a noteWe will only ever use your address to say a game is ready. No marketing machine, no tracking, no selling your details. Reply to stop. That is the whole policy.
