Drag it, or tap twice
Carry a sweet to its hollow, or tap the sweet and then the square. Small hands get to pick the way that works.
Four colours, four hollows, one sweet in each row.
EasyShidoku is sudoku on a 4×4 grid — the whole rule, none of the bookkeeping. Colour carries each number, so a five-year-old can finish a board before they can read one, and chapter six leaves you four clues and a single way in.

Tap a square, then a colour. Or drag one across.
10 squares leftThe colour is the number
One is pink, two apricot, three mint, four sky — on the icon, on the board, on the tray. The hue never moves. For a beginner that means matching comes first and reading follows; for everyone else it means a board you can read at a glance on a moving train.

The first chapters mark a wrong sweet the moment it lands. From chapter three they hold it back until the board is full — checking your own work is the part worth learning.
Clues look the same
The sweets already on the board sit a little lower in the tray. Same sweet, same colour — just one that will not move.
It starts with one square
Discovery is a single box of four with one empty hollow: the only rule is that each colour appears once. Practice widens the board so rows start to matter. From Bronze on it is a real 4×4 — and Master leaves you four clues and one way in.
150 levels in all, three stars each. Stars open the chapters ahead —Bronze at 45, Master at 288 — and anyone stuck on one level can earn them somewhere else.

Good to know
No account, ever
Nothing to sign up for and nothing to type. Progress lives on the device.
Game Center
Optional. Stars travel between your devices, and the daily puzzle has a leaderboard.
Light, dark, or neither
The board follows the device by default, and can be pinned either way in Settings.
Built for both
On iPad the board keeps to a column within reach rather than running to the edges.
Eleven languages
German, Spanish, French, Italian, Japanese, Korean, Dutch, Vietnamese, Chinese and English.
Ads, and a way out of them
The game is free with small ads. $1.99 removes them and opens every level at once.
The free version shows ads served by a third-party network, which reads a device advertising identifier. What that covers, and what it does not, is written out on the privacy page.
