About this game

Codoku is Sudoku that teaches you to think like a coder.

Same Sudoku rules
Every row, column, and box still needs unique tokens. The puzzle is the lesson.

Start with numbers
Play a classic grid right away. New packs unlock by playing, not by paying.

Learn code tokens
Move from numbers to variables, types, operators, and if/else, one grid at a time. The words change. The constraints stay.

Also in the app
• A skill map and a skills overview
• Optional 4×4 expression side quests
• A short run report when a grid compiles
• Guides you can buy with credits you earn
• Remove Ads as a one-time purchase

Codoku does not teach a whole programming language. It is practice for logic, constraints, and the vocabulary programmers use.

The free game can show an ad after you finish a level.
