Welcome! Whether you’re here to learn the ropes or shave swaps off your score, these FAQs cover everything you need to know about Swudoku.
Let’s get into it.
Core Gameplay FAQs
1. What is Swudoku?
Swudoku is a daily logic puzzle where you swap tiles on a scrambled sudoku-style grid to restore order.
The name literally comes from Swap + Sudoku. Get it?!
Each puzzle starts fully filled — nothing to type — and your job is to untangle the grid using pure logic.
2. How do I play Swudoku?
Tap a tile, tap another tile, and the two will swap.
Your goal is to place every number back into its correct spot using as few swaps as possible.
No timers. No pressure. Just strategy.
3. What do the colours mean?
The colours tell you how your grid is shaping up:
- Blue (4) — The cell you’ve currently selected
- Yellow (2) — This number is in the correct position
- Green (3) — Correct position and part of a complete row, column, and block
- Grey (1) — A swappable cell
Once the whole board is green, you’re done.
4. How do swaps work?
Pick any two cells and tap them in order. They switch places instantly. If the swap improves the grid’s correctness, your colours will update.
5. How do I win a game of Swudoku?
You win when every tile is in the right place.
Green across the board.
Job done.
Better still? Win with the fewest swaps possible.
6. Is Swudoku timed?
Nope.
Chess isn’t a race, and neither is Swudoku.
This is a game about clear thinking, not fast tapping.
7. What makes Swudoku different from regular sudoku?
Traditional sudoku makes you place numbers in empty cells.
Swudoku already has numbers in every square — you just need to move them into the right spots.
Same game logic. New twist. Touch-friendly. Satisfying.
8. Is Swudoku suitable for beginners?
Absolutely.
If you’ve never touched sudoku, you’ll still pick this up in seconds.
If you have played sudoku, you’ll feel right at home.
9. Does Swudoku use standard sudoku rules?
Yes — every puzzle follows classic sudoku logic:
- Each row must contain 1–9
- Each column must contain 1–9
- Each 3×3 block must contain 1–9
You’re just solving those rules through swapping instead of writing.
10. What is a “Double Swap” in Swudoku?
A Double Swap is when swapping two tiles instantly puts both of them into the correct position. It’s one of the most satisfying moments in the game — the logic equivalent of sinking a long putt or hitting the perfect cover drive.
Double Swaps don’t just feel good… they’re powerful.
They save you moves, tighten your route to a GOAT score, and help you clean up messy sections quickly.
If you’re aiming for a low swap count, always keep an eye out for potential Double Swaps. They’re the quiet heroes of efficient solving.
