Chiidoku 400 Levels Campaign Guide

A source-checked guide to the campaign's level counts — the October 2026 Catdoku listing's 'over 1,000 levels' claim and the documented 400-level ladder before it — and the level details that are still not publicly documented.

Quick answer

Official listing (rechecked October 25, 2026): over 1,000 levels.

The official listing — renamed Catdoku on October 15, 2026, same game as Chiidoku — now says 'complete over 1,000 levels, earn coins, set your best win streak', replacing the September-era claim of up to 400 Standard levels. The listing still provides no campaign map, level order, solutions, unlock rules, or difficulty curve for either count, so this guide keeps the published numbers separate from undocumented walkthrough claims. The 400-level band table below remains the community wiki's documented breakdown of that earlier ladder.

Campaign routine

Progress with the current published counts

The current Catdoku listing supports the 'over 1,000 levels' claim, the row, column, colour-region, and no-adjacency constraints (worded as Cats), plus a personal-best streak. The Endless row is no longer listed, though community wikis still describe the mode. Neither count comes with a map of which level introduces a rule or what a particular board requires.

Identify the row, column, region, and nearby cells that constrain your next placement.

Use on the current puzzle

Current count

Use the published upper bound

Use 'over 1,000 levels' as the current official claim (October 2026); the up-to-400 wording it replaced — and the even older 300-level wording — are superseded, not current totals.

Keep the count separate from maps

Mode split

Separate modes

Use the endless-mode page for the separate unlimited random challenge instead of assuming its rules are campaign progress.

Common mistakes

What to avoid

  • Do not keep repeating the superseded 300-level or 400-level wording as the current total — the listing now claims over 1,000 levels.
  • Do not turn either published count into a published solution map.
  • Do not assume endless mode is part of the campaign count.
Checked date

What the official update confirms

Rechecked October 25, 2026 (wording unchanged since the October 15 rename update). The listing — titled Catdoku since that update — states 'complete over 1,000 levels' with coins and win streaks; the September 1 snapshot's up-to-400 Standard-levels row and its new-themes advertising are now the documented history, and theme names, theme rules, level maps, and solutions remain unpublished.

Questions

Campaign level-count FAQ

Answer

How many levels are in Chiidoku?

Rechecked October 25, 2026: the official listing — now titled Catdoku, the new name for Chiidoku — says 'complete over 1,000 levels', replacing the September wording of up to 400 Standard levels. A level-by-level map or complete solution list is still not publicly provided for either count.

Answer

Is there a guide for every Chiidoku level?

No verified public level-by-level solution list is available here. Use the puzzle-rule guide and the in-game board rather than assuming a fixed walkthrough.

Answer

Is endless mode part of the level count?

The September listing described endless mode as a separate random-puzzle mode with no level limit; the October 15, 2026 description rewrite no longer lists an Endless row at all. This guide treats endless play separately from the campaign ladder either way.
