Keeping it a puzzle
There is no money in One Stroke, but any game can quietly take more evening than you meant to give it.
What is deliberately missing
No daily streak, no notifications, no reward for returning. The game has no idea who you are and cannot miss you.
A reasonable habit
Solve a sheet or two, then put it down. If you are drawing lines to avoid something else, the puzzle is doing a job it is bad at.
If it stops feeling optional
Talk to somebody. Lifeline is on 13 11 14, any hour, and Beyond Blue on 1300 22 4636. Free and confidential, both.
For parents
Nothing to spend, nobody to talk to, no adverts. The only adult part is the email form for build links.
