Sudoku by Dolga
In development
Sudoku with a promise: every puzzle has exactly one solution, and logic alone will find it. No guessing, no second answer hiding in the grid.
Coming soon — in development now
Only from Dolga
One puzzle. One solution. No guessing — ever.
Every Sudoku by Dolga puzzle is proven unique before it reaches you, and graded by the hardest technique its solve actually needs — so the difficulty on the label is the difficulty in the grid.
About
Sudoku by Dolga is the number puzzle on a warm paper board — givens in ink, your entries in Dolga green, the selected cell lit gold. Four difficulty bands — Easy, Medium, Hard, Expert — each with a published technique ceiling, so you always know what a band asks of you.
Time is the score: a live timer, your best time per band, and a fastest-time leaderboard for each. There is a fresh Daily puzzle every day — the same grid for everyone — and any puzzle can be shared as a code for a friend to race. Need a nudge? The Hint comes from the same solver that graded the puzzle, and honest bookkeeping marks the game assisted.
Paid once. No ads, no in-app purchases, no subscriptions.
