What’s new
Version 1.6 · Updated September 26, 2026
Sudoku Classic Puzzles is rebuilt from the puzzle up. • A new generator: every board has exactly one solution, and the clue counts are now exact — Easy 42, Medium 34, Hard 28. • Two ways to play: Classic, where three mistakes end the round, and Chill, with no failure state and a timer you can switch off. • An aquarium that grows as you solve: finished puzzles pay coins, which you spend on guppies, goldfish and angelfish and on the food that keeps them happy. • Rounds now survive interruptions: reopen the app and you are back on the same grid, the same clock and the same pencil notes. • Pencil notes, undo, erase and hints, with coins, timer, mistakes and your daily streak at a glance. • Portrait on iPhone and iPad, with the board, pad and action bar fitting one phone screen. Ads keep the game free: a small banner sits at the bottom of the screen, and a rewarded video is always optional — watch one to double your coins or claim a free hint. Nothing interrupts a puzzle you are in the middle of. Thanks for playing, and for the wait: this release was rebuilt from the puzzle up.
