Lagos Life Age Limit: 18+
Quick answer
You must be 18 or older to play Lagos Life. The official terms of service say so directly, and state that accounts believed to belong to younger players may be closed.

The exact wording
"You must be 18 or older. By signing up you confirm you are. We may close accounts we believe belong to someone younger."
Why the limit exists
The game is an open multiplayer world with chats, player-run ads and in-app payments. Its own privacy policy repeats the 18+ rule and says data from anyone younger will be deleted if discovered. We quote the rule rather than guess at the reasons — the game does not publish more than this.
