About

Overview

Chiidoku is a puzzle game that mixes Sudoku logic with Minesweeper-style rules, using Chiikawa characters instead of numbers. You place one character per row, per column, and per color, making sure no two characters touch — even diagonally. This guide walks you through the rules, the four modes, and how to push through harder levels without getting stuck.

The three rules every puzzle is built on

Check

In short Keep all three rules in mind at once, because breaking any one of them makes the puzzle unsolvable.

Every puzzle in Chiidoku has exactly one correct answer, and you can always reach it through logic alone — no guessing needed. The three rules below apply to every single puzzle, no matter how far you get.

One character per color each color has exactly one matching character, so once you place it, that color is done.
One character per row and per column no row or column can ever hold two characters.
No touching, including diagonally two characters cannot be in any of the eight squares surrounding each other.

The four modes and when to play each

Table

In short Start with Standard to learn the rules, then branch into the other modes once you feel comfortable.

Each mode has a different goal, so picking the right one for where you are saves a lot of frustration.

Standard	the main mode, with levels to work through, coins to earn, and a win-streak counter to chase.
Ranked	you and other players solve the same puzzle at the same time, and the fastest correct finish wins.
Endless	randomly generated puzzles that keep coming, with no level cap.
Daily Puzzle	one fresh puzzle every day that resets every day, with a reward for completing it.

Progress milestones in Standard mode

Step

In short The six badge levels give you clear short-term targets so you always know what to aim for next.

Standard mode hands out a badge each time you hit one of six milestone levels. The puzzles get harder as the numbers climb, but the three core rules never change — so the solving method stays the same throughout.

Level 1 finish the tutorial and confirm you understand all three rules before moving on.
Level 5 by here the basic moves should start feeling natural.
Level 10 a sign that your skills are genuinely developing.
Level 50 reaching this shows you can keep your momentum across a long run of puzzles.
Level 100 the game considers you a skilled player at this point.
Level 500 the expert milestone and the biggest goal Standard mode offers.

What to do when you get stuck

Warn

In short If a puzzle feels impossible, you have almost certainly missed a diagonal-touch violation — go back and check that rule first.

Because every puzzle is solvable by logic, hitting a dead end means a rule was broken somewhere earlier. Work back through each rule in turn rather than guessing your way forward, since a wrong guess just creates more conflicts to untangle.

Worth watching out for

Check every row for two characters sharing the same row.

Check every column for two characters sharing the same column.

Check every character's eight surrounding squares for another character the diagonal touches are the easiest ones to miss.

Getting the most from Daily Puzzles and Ranked

Tips

In short Logging in every day for the Daily Puzzle is the most consistent way to collect rewards over time.

Daily Puzzles refresh every day, so a puzzle you skip is gone for good. Ranked mode puts you against other players solving the same puzzle, where speed matters alongside accuracy.

Tips worth knowing

Check the Daily Puzzle every day before it resets — missing a day means missing that day's reward.
Ranked games use the same puzzle for all players simultaneously.
Once you have cleared Standard, Endless mode keeps generating new random puzzles so the challenge never runs out.

Glossary

Win streak: The number of Standard-mode puzzles you have completed correctly in a row without a mistake.
Diagonal touch: Two characters sitting in squares that share only a corner, which is illegal in Chiidoku just like side-by-side touching.
Daily Puzzle: A single puzzle that refreshes every day and gives a reward when completed.
Ranked mode: A competitive mode where every player solves the same puzzle simultaneously and the fastest correct solution wins.

Common questions

FAQ

Do I ever need to guess?

No — every puzzle is designed to have one solution reachable through logic alone. If you feel like you have to guess, it almost always means a diagonal-touch violation was missed somewhere. Run back through all three rules and you will find the opening.

What should I do after finishing Standard?

Endless mode keeps producing randomly generated puzzles, so you can keep sharpening your skills there. Ranked mode and the Daily Puzzle also stay fresh indefinitely, since Ranked pits you against other players and the Daily Puzzle resets every day.

Is Ranked mode right for beginners?

Ranked asks for both accuracy and speed at the same time. Work through enough Standard levels to place characters quickly and confidently, then move to Ranked when solving feels routine.
