About Sudoku Mini
Sudoku Mini is a compact version of the classic number puzzle. A four-by-four grid must be filled so that each row, column and two-by-two box contains the digits 1 to 4 exactly once. It is a gentle introduction to logical deduction, and the number of blanks grows with each level.
How to play
- Tap an empty cell, then tap a number below the grid.
- Every row, column and 2x2 box must contain 1, 2, 3 and 4 once each.
- Conflicting numbers turn red. Fewer mistakes earn more stars.
Tips and strategy
- Start with the row, column or box that already has the most numbers.
- For each empty cell, list which digits are still missing from its row, column and box.
- If a digit can only fit in one cell of a row, place it there.
Levels, stars and XP
Finish a level to earn one to three stars and XP towards your player level. Replay any unlocked level to improve your stars. From level 151 the game enters endless mode, where each level is a remix of an earlier one with fresh colours and a slightly higher difficulty.
