Sudoku Sova - Number Puzzle

Five kinds of grid now — classic, Killer, X-Sudoku, Windoku, Jigsaw — and a level above Master. Sova still never fills the cell for you.

Most sudoku apps tell you WHAT to put in a cell. Sudoku Sova teaches you WHY.

Meet Sova, your technique-based sudoku coach. Stuck? Hints unfold in three gentle steps: first the area to look at, then the name of the technique, and only then the full lesson. Placed a digit yourself? Tap "Why is this right?" and Sova names the deduction you just made — hidden singles, pointing pairs, X-Wings — so next time you'll see it on your own.

FIVE GRIDS, ONE COACH • Classic sudoku, seven levels from Fast to Master — and Extreme above them, where two-string kites, finned X-Wings, unique rectangles, BUG+1 and XY-chains live • Killer Sudoku: cages and sums, coached step by step • X-Sudoku, Windoku and Jigsaw: the diagonals, the four windows, the irregular regions — each with its own four levels and its own lessons • A Daily Challenge in all of them — the classic grid, the killer, and whichever variant the date carries. The same puzzle for everyone, everywhere.

WHAT MAKES SOVA DIFFERENT • A real coach, not an answer machine — every hint is a small lesson • Honest difficulty: levels are graded by the techniques they need, never by counting givens. No guessing, ever — every puzzle solves by pure logic. • A kind daily habit: 5 of the last 7 days keep your streak alive. No punishments, no guilt. • A year worth keeping: every daily lights a star, every month completes a constellation, and the year's events leave keepsakes in your night sky • Watch your skills grow: 24 techniques, each one named, drawn and practisable

EVERYTHING YOU EXPECT, DONE CAREFULLY • Your first board is walked through, one real deduction at a time • iCloud backup: your statistics, streaks and everything you have earned open on a new phone where you left off • Notes, undo, auto-clean pencil marks, smart highlights, mistake counter • Cell-first or digit-first entry — play the way you like • Statistics by week, month or year: best time, average, win rate • Full iPhone and iPad support, portrait and landscape • 20+ languages, offline play, no account needed

One "remove ads" purchase, and that's it. No coins, no subscriptions, no energy bars. Just sudoku, and a wise owl who makes you better at it.
