Sudoku Gridmaster — About this game
Fill the grid with numbers from 1 to 9 so that each row, column and outlined 3×3 block contains no repeats. Practice highlights incorrect entries in red, while Easy, Normal and Hard leave the deductions to you. Touch entry can be switched to handwriting, and each cell can hold up to four small candidate notes. Solve grids to earn stars for bonus boards, and progress towards separate timed Rank Tests for another challenge. Save & Exit keeps an unfinished puzzle available through Resume when you return.
