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.
Sum Challenge Number Grid gives a child a game that is theirs to manage. It is free, runs in the browser with nothing to download and no account, and the stages are short enough to finish before attention wanders. Parents can glance at the screen and see exactly what is happening.
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.
