2. 2Use arrow keys or on-screen buttons to move, and tap or press space for jumps and actions.

One Line is free, runs in any browser with nothing to download, and suits a child who wants to play on their own for a bit. The stages are quick and the difficulty is kind, so most sessions end with a success rather than a sulk.

Suits children from about five upward who can read a few words and manage simple controls. Good for solo play on a tablet or laptop, with an adult nearby for the youngest.

Is One Line too hard for a five-year-old?

Probably not, with a little help at first. Junior games are built for early school-age children. The first stages are gentle and the controls are simple.

Can I use a phone?

Yes, though a tablet gives more room for the on-screen buttons and makes small items easier to see and tap.

Does the game explain itself?

Yes. Most junior games show a picture or short line at the start of each stage and highlight the first thing to do.
