Big blocky worlds.
Zero strangers.
BuildKins is a multiplayer playground where kids build, race, and explore with real friends — and where no one can send your child a private message, ever. Safety here isn't a setting you switch on. It's the way the whole thing is built.
No open messaging
No chat box, no DMs, no private messages. Kids can add friends to play together — there's just no way to send anyone words, because we didn't build one.
Names we choose
Every player is a friendly handle like BraveBlueFox — picked from a safe word pool. Kids never type a free-form name, so no one hides a message in one.
Every game reviewed
A person plays every game before it goes live and checks it against a fixed list — no loot boxes, no streak pressure, no pay-to-skip.
No engagement traps
We don't track playtime to keep kids hooked. There's nothing designed to pull them back for “just one more.” When they're done, they're done.
Four worlds to start. More on the way.
Color Dash
The floor calls a color — dash to the right tiles before the rest drop away.
Tower Hop
Climb the rainbow spiral tower. Checkpoints save your spot — race to the golden summit.
Maze Game
Find your way through a moody midnight maze. Race friends to the exit.
Thundering Skies
Storm-chase across the plains — pick a job, drive, and outrun the weather.
Kids can still cheer each other on — just not in words they type.
Players communicate with emotes and a set of ready-made phrases like “Good game!” or “Follow me!” Every phrase is written by us and shows up in each player's own language.
Because there's no free typing anywhere in the game, there's no place to slip in a phone number, a “meet me here,” or anything you'd have to read after the fact. The list of things a child can say is fixed, and we wrote all of it.
A short list of things BuildKins will never do.
Your child is not the product. We don't run ads or sell data.
No free-text messaging is coming later. It can't be — it isn't in the wire protocol.
No gambling mechanics, no mystery boxes, no random paid rewards.
No daily streaks, no countdown timers, no "your friends are playing" nudges.
In-game items are optional and shown in real money — never a confusing coin currency.
We don’t collect playtime analytics. We can’t tune for "engagement" we refuse to measure.
Want your kid on the list?
We're in a small private beta with families we know and their friends. Request an invite and we'll reach out to the grown-up in charge.
