Chiidoku Getting Started

What you just joined

Chiidoku is a free Roblox logic puzzle released on 4 August 2026 by 미지 스튜디오 (Unknown404_Dev). The loop is small on purpose. You look at a colored grid, you place Chiikawa tokens, and the board either sings or eats a heart. Servers can hold up to 50 people, but every puzzle is yours alone. Nobody else can click your cells for you.

The studio describes the game as Sudoku mixed with Minesweeper. In practice that means uniqueness plus careful placement, not a hidden minefield you tap at random. You can see every color. You can see every empty cell. The danger is committing too early.

Read this page once, then keep the solve guide and the strategy checklist nearby. If you only want cosmetics later, jump to how to get coins after you survive the first dozen boards.

The three official rules

The Roblox description is short. Memorize it before you touch the grid:

1. Each row contains exactly one Chiikawa.
2. Each column contains exactly one Chiikawa.
3. Each color region contains exactly one Chiikawa.
4. Chiikawas cannot be placed next to each other.

That last line surprises players who arrive from Queens-style puzzles. In Chiidoku, adjacent tokens are illegal and will cost a heart. Do not try to place two Chiikawas beside each other — the game already forbids it.

Color regions replace Sudoku’s 3x3 boxes. A region can be a compact blob or a snaking polyomino. On early boards the shapes are friendly. By the later campaign they share long edges and force you to think in rows and columns at the same time.

How a turn actually feels

Tap or click an empty legal cell to place a token. Tap it again if the UI allows a take-back. Confirm the control list in Chiidoku controls because mobile, console, and PC layouts differ in padding, not in logic.

A placement is winning when it does not break a row, column, region, or place tokens adjacent to each other. A placement is losing when it leaves some unit with zero legal cells or violates the adjacency rule. You do not always see the loss on the same tap. Sometimes the board still looks fine until three moves later, when a purple region has nowhere to go. That delayed fail is why guessing feels cheap and then expensive.

Hearts are the punishment layer. The Heart + 1 pass adds a spare life. It does not mark the correct cell. If you are still guessing, buy the pass after you finish this guide, not before.

Your first session, in order

Do not open infinite mode on minute one. The random generator is for streaks after you trust the three rules.

1. Launch from the official Chiidoku page.
2. Sit through any tutorial prompts. They exist to show placement, not advanced technique.
3. Clear the first easy boards by hunting forced cells: a region whose only remaining empty cell is also legal in its row and column.
4. When two cells both look legal, do not flip a coin. Pencil the pair mentally, then look for a row that already has a token. One of those two cells is probably dead.
5. After a handful of clears, open daily missions and cash the easy coin tasks.
6. Only then peek at the character shop. Cosmetics do not change legality.

If a board stalls, leave it and read how to solve Chiidoku. Coming back with a method is faster than restarting in a huff.

Campaign versus the rest of the HUD

The campaign is the 400-level ladder. Difficulty ramps. Streaks on the campaign still matter because they train the same muscles you need later. Infinite mode removes the numbered ladder and feeds you generated boards until you break. Daily missions sit beside both modes and reset on a clock. Coins from those tasks buy the roster on the characters hub.

There is also a codes door. As of 29 August 2026 the studio has not published a public working string. Still learn how to redeem Chiidoku codes so the first shout is not wasted.

What “Minesweeper” is doing here

You are not revealing hidden mines. You are placing a known number of tokens under uniqueness constraints. The Minesweeper flavor is the local counting: each empty cell either can hold a token or it cannot, and neighbors matter because adjacency is banned, not because they occupy a row, column, or region.

If you treat every empty cell like a 50/50, you will burn hearts. If you treat every empty cell like a candidate list, you will finish 400 levels.

Mistakes worth killing on day one

• Copying Queens adjacency rules into Chiidoku.
• Placing two Chiikawas next to each other (this is explicitly forbidden).
• Filling a pretty color first instead of the tightest constraint.
• Ignoring a row that already has its token and still “testing” cells in that row.
• Opening infinite mode to “practice” before you can clear a campaign board without panic.
• Spending Robux on 2x Rewards before you can finish dailies consistently. Double rewards on zero clears is still zero.

Where to go next

Keep this page as the rule sheet. Use how to solve as the technique sheet. Use the tier list hub when you start caring about which pass or cosmetic is worth the grind. Use updates after patches, because a new mission type will show up there before it shows up in rumor.

Chiidoku is easy to learn. The studio says so. Completing every puzzle is the actual product. Play slowly for one evening, then speed will arrive on its own.
