Rooky

Rooky teaches chess to children who are too young to read.

Every control is a picture. Nothing on the playing screen needs a word to
make sense of it, so a four-year-old can pick it up and start playing without
an adult reading the buttons out.

One piece at a time
Six worlds teach a single piece each — how a knight hops, why a bishop never
leaves its colour — before six more introduce the ideas: taking, protecting,
check, escaping check, and finishing the game. Nothing is thrown at a child
all at once.

Getting it wrong costs nothing
When a piece is taken, the board plays it out and quietly steps back one
move. There is no losing screen and no scolding, and trying again earns
rewards of its own, because a child who is frightened of being wrong will not
attempt the harder puzzle.

Stars, stickers, and things you have done
Finishing a level earns stars, stars fill a bar, and a full bar buys a
sticker chosen from three. Achievements reward the pieces a child likes
playing with, not only forward progress.

Room for more than one child
Each profile keeps its own progress, its own stickers, and its own
difficulty. A grown-up can cap how hard the puzzles are allowed to get,
separately for each child, so an older sibling and a beginner can share one
device.

No strings
No adverts. No in-app purchases. No accounts and no sign-in. Rooky works
entirely offline and needs no internet connection: it collects nothing and
sends nothing anywhere, because it has nowhere to send it to.

Best for ages 4 to 8, and for anyone learning how the pieces move.
