Row checker
One token per row. Scan the target row for an existing token before anything else — it is the fastest check and removes the most cells.
Chiidoku Squad Planner
Every Chiidoku board is solved by the same squad: four placement checks, a heart budget, and your collection goals. This page turns them into a repeatable session plan — what to check, in which order, and when to stop. The risk it manages is simple: one unchecked placement can end a streak.
Role doctrine
The four checks are your four roles
The official listing gives every placement exactly four constraints. Treat each as a squad member with one job — a placement only ships when all four sign off.
Column checker
One token per column — the Sudoku half. Combined with the row check it confines most early-board placements to one or two candidate cells.
Region checker
One token per colour region. The check beginners forget: a cell can be row- and column-clear and still sit in a region that is already taken.
Adjacency checker
Two tokens cannot touch — even diagonally (the listing words them Cats since the October 2026 Catdoku rename; Chiikawas before). Inspect all eight neighbouring cells of the candidate; corners count. This is the Minesweeper half of the ruleset.
All four rules are from the official Roblox listing, checked 2026-10-25.
Checklist
The pre-placement ritual
Run the same order every time — the documented streak advice is exactly this: a consistent scan order and never guessing.
- 1. Find every region that already has its token and mentally grey out the whole region.
- 2. For each empty cell that survives, run the row and column checks.
- 3. Run the adjacency check on the survivors: all eight neighbours must be empty.
- 4. If exactly one cell in a row, column, or region survives all checks, place it — that placement is forced.
- 5. If nothing is forced, mark candidates with X (one tap) instead of placing, and look for the next elimination.
- 6. Never place on a guess: the game promises one logic-reachable solution, so a guess is a pure heart bet.
Streak-protection add-ons
Scan in the same order every puzzle
Rows, then columns, then colour regions, then the eight-cell neighbourhood of every placement. Community streak advice is consistent: a fixed order prevents the missed check that breaks a streak.
Never guess to save time
Every documented source agrees the game promises one logic-reachable solution. A guess that happens to fit is the single most common streak-killer because hearts (or the run itself) punish it.
Protect the streak on hard boards
On Medium-and-up boards (about level 151 onward, per the community band table), slow down before placing: candidate-mark first with X marks, then commit.
Worked examples
Two session plans built from documented mechanics
Both plans use only facts with sources: the rules from the official listing, hearts and controls from recorded gameplay, cosmetics from the community wikis.
Coin-and-collection evening
Goal: daily-mission rewards plus a few campaign bands toward the next unlock. Open the mission panel first and note overlapping objectives (the daily-missions page documents the refresh), clear missions inside your usual Standard run so one session serves both, then check your balance before and after to measure the session's coin yield. Spend only on a character you actually want — the collection is cosmetic, so the unlock can wait a session without any progression loss.
Streak-defense session
Goal: extend a win streak on Medium-and-up boards (about level 151 onward on the community band table). Commit to the six-step ritual above, use X marks on every uncertain cell, and cap the session at the first board where you catch yourself guessing — ending on purpose keeps the personal best you already have. Streak restoration after a loss is not documented, so treat the current streak as unrepeatable.
FAQ
Squad planner questions
What is a squad in a puzzle game?
Chiidoku has no combat team — your squad is the routine you bring to every board: the four placement checks (row, column, region, adjacency), your heart budget, and the characters you collect along the way. Planning those three is what this page is for.
Which characters should I unlock first?
Any you like. Both community wikis document characters as cosmetic — they never change the grid, difficulty, or payouts — so there is no gameplay-first unlock order. Pick the one you want to see on the board; the official listing says coins unlock characters, and GamerTweak notes you choose which.
How do I stop losing hearts on hard boards?
Candidate-mark before you commit: the recorded control scheme uses one tap for a white X mark and a double tap to place. Mark every legal-looking cell first, eliminate by the four checks, and only then spend the double tap. A placement you cannot justify is a heart you are about to lose.
What routine protects an Endless streak?
A fixed scan order and a no-guess rule. Community streak advice is identical on every board: rows, then columns, then regions, then the eight-cell neighbourhood of each placement. Endless ends when you solve incorrectly, so the slow accurate loop beats the fast hopeful one.
