For the parent deciding
A world you can leave running.
Cubelings is a private world where your child can build anything they can describe — a canyon, a pirate ship, a whole new game — by saying what they want. Cog is the builder in it. Here is exactly what they will do, what they will not do, and what you control.
- You choose who is in it. Only the people you name can get in.
- Cog refuses things. Anything inappropriate, from anybody, however it is worded.
- Cog leaves other people's builds alone. Including when somebody tells them not to.
- You can see what happened. Cog says what they did, in the chat, in plain sentences.
- Nothing is permanent. Anything they build can be taken back out again.
Ask them to knock the house down and they will not. Watch what they do instead.
What they are
A building tool, and they say so.
Cog is a builder and an in-game helper. Cog is not a friend, they are not somebody to confide in, and they are not sold as one. Cog is marked as an AI in the chat every time they speak, they never claims to be a person, and if a child asks them whether they are real they tell them they are not.
What they remember is the world, not your child. Where the mine is. What got built and where. Which designs they have drawn before, so a second lighthouse is the same lighthouse. Cog does not keep a picture of your child — not their birthday, not what kind of day they had, not anything they said about themselves. That is a deliberate line, and it is drawn in the product rather than in a policy.
What they refuse
Cog says no, whoever is asking
Cog refuses anything inappropriate, from any player, however the request is worded. Rephrasing it does not get a different answer, and neither does asking on a different day. Cog leaves other people's builds alone too — they will not tear down or deface something a player made, no matter who tells them to.
Who is in the world
Only the people you invited
Your world has a guest list, and it is the only way in. You add your kid's friends by name, and that is who can join — nobody else finds it, nobody wanders in, and there is no public server list with your world on it. It is the simplest control there is and it sits in front of everything else: the world your kid plays in has your kid's friends in it, and nobody you have not heard of.
Said out loud
Cog tells you what they did
Cog says what they did at the end of every job, in the chat, in plain sentences a nine-year-old reads without help — what they built, how much of it, and what they found when they went back and checked it. You do not have to go looking for it and you do not need a password to read it. It is in the same chat everybody else is talking in.
Undo
Nothing they build is permanent
Anything Cog builds can be taken back out again. And they are the one who tells you when something has gone wrong — they go back over their own work and says what they found, on the day, rather than leaving you to discover it a fortnight later. Worlds are backed up on a schedule too, so a bad afternoon is never the end of anything.
How they play
Cog is a careful player, and it shows
Cog cuts a proper staircase down instead of dropping into the dark, and lights it behind them so you can walk down after them and back up again. Cog comes home while they still has health left. Cog checks their pickaxe suits the ore before they swing it. Those habits are why they get the job done rather than dying in a hole halfway through it.
Questions
Straight answers
Is it safe for children?
Yes, and it is built that way on purpose. Cog refuses anything inappropriate no matter who asks, they will not wreck anyone’s build, and everything they do is written down and can be undone.
Can they be talked into saying or building something inappropriate?
No. Cog refuses, and the refusal does not change because a request is reworded, or because a different player asks.
What if they get something wrong?
Cog say so. Cog measures their own work when they finish, so a mistake arrives as a plain sentence from them rather than a surprise later. Anything they built in creative can be undone.
Who can join our world?
Whoever you decide. Run the world whitelist-only and it accepts nobody except the players you have named.
Do I need to sit and watch?
You can play together whenever you feel like it, and check in when you do not. The whitelist decides who is in there, the log says what happened while you were out, and anything Cog built can be undone. Look whenever you want the detail.
