More to play

24 games

Junior games sit between the simplest toddler games and the full catalogue. They assume a child can follow a two-step instruction and read a short word or two, and they build from there. A session might be a gentle platformer, a counting puzzle, a coloring activity or a simple driving game. Stages are short, failure is soft, and the difficulty climbs slowly enough that a child can feel it.

How to play

1Press Play and read or listen to the short instruction on the first screen; it tells you the goal of the stage.
2Use the arrow keys or on-screen buttons to move, and tap or click to pick things up or answer.
3Collect stars, coins or ticks as you go; they usually show how well a stage went.
4At the end of a stage, tap next to continue or replay to try for a better result.

Who it's for

Suits children of around five to ten who have outgrown toddler games but are not ready for faster, harder titles. Parents and older siblings may help with the odd instruction.
