One purchase, not a subscription
Remove the ads once and they stay gone. The category's loudest complaint is the opposite: a weekly charge to hide ads, with no one-time buy on offer.

Why Stixa
The result comes before the ad
You always see how you did before you see an ad. Finishing a puzzle is never the moment we interrupt.
Two games sharing one Daily
Nonogram one day, sudoku the next — the same puzzle for everyone. One calendar, one streak, one set of achievements for both.
It never runs out
Puzzles are generated and verified, not picked from a finished list. There is no "you have completed every level" screen.
Honest difficulty
The label comes from what the puzzle actually demands — which deduction techniques, and how deep — never from how big the grid is. An "expert" here is expert.
Always deducible, never a guess
Every nonogram has exactly one solution, reachable by pure logic. The generator rejects any puzzle that would need guessing.
Checking is free
Pointing out mistakes is not a paid hint. Undo and redo are unlimited, in both games.
Works offline. No account.
Stixa runs entirely on your phone. The connection is only used by the ads and the purchase.
How it works
- 1
The numbers on the edges say how many cells in a row to paint, in each line and column.
- 2
Tap to paint, long-press to mark what is empty, drag to paint a whole line.
- 3
When the grid closes, the picture is revealed — and only then does it get a name.
- 4
In the sudoku, the same calm: notes by hand or filled in, free checking, and unlimited undo.
Frequently asked questions
Does it work without internet?
Stixa works offline: runs, the Daily, the calendar, stats and achievements all live on the device. The connection is only used by the ads and the purchase.
Do I need an account?
Stixa asks for no account, no login and no e-mail. Nothing you play leaves your device.
Is removing the ads a subscription?
No. Removing the ads is a one-time purchase with no renewal. That is the difference that shows up most in complaints about the competition.
Do the puzzles run out?
No. They are generated and verified one by one, so the track has no end and the Daily never repeats.
Will I ever have to guess?
Never. Every published nonogram passes a solver that does not guess: if it cannot be solved by logic, the puzzle is discarded.
Can I play the big grids on a phone?
Yes. When a cell would be too small to tap, the board gets zoom and pan instead of shrinking.
