Sudoku Mini
4x4 with pictures, up to the real thing
About Sudoku Mini
Sudoku that starts as a 4x4 picture puzzle for five-year-olds and scales to a full 9x9 with pencil marks.
Ankhdase tracks 2 distinct skills in Sudoku Mini, including Deduction and Strategy & planning. Because mastery is estimated per skill rather than per game, the questions shift toward whatever a student is getting wrong — and away from what they have already proved they know.
How to play
- Every row, every column and every box must contain each symbol exactly once.
- Tap a square then tap a symbol below — or use the number keys.
- Pencil mode lets you jot possibilities without committing.
Skills Sudoku Mini practices
- Deduction
- Strategy & planning
Mastery is estimated separately for each of these, which is what lets the difficulty move independently — a student can be fluent on one and still be fed easier questions on another.
