CHECKED LEVEL ANSWER
Chiidoku Level 4 solution
A 4 × 4 board. Match the colored regions below before using these coordinates.
R1C2, R2C4, R3C1, R4C3
Rows count down from the top; columns count from the left. Each dot below represents one character.
Match your layout
| 1 | 2 | 3 | 4 | |
|---|---|---|---|---|
| 1 | G | V | Y | Y |
| 2 | G | G | Y | Y |
| 3 | G | G | Y | Y |
| 4 | G | G | P | P |
G = Mint · V = Violet · Y = Yellow · P = Pink
The completed placement
| 1 | 2 | 3 | 4 | |
|---|---|---|---|---|
| 1 | G | Y | Y | |
| 2 | G | G | Y | |
| 3 | G | Y | Y | |
| 4 | G | G | P |
G = Mint · V = Violet · Y = Yellow · P = Pink
Why these squares work
R1C2 — violet
The violet region contains only R1C2.
R2C4 — yellow
R2C2 reuses the occupied column; R2C1 and R2C3 touch the first piece diagonally. R2C4 remains.
R4C3 — pink
Pink occupies R4C3/R4C4. Column 4 is occupied, so use C3.
R3C1 — mint
The only unoccupied column is 1; its row 3 square is mint.
Levels 2, 3 and 4 happen to share these final coordinates in the checked recordings, but their region layouts differ. Do not generalize this pattern to later levels.
Completion check and source
Finaq’s 2026-08-30 recording shows this layout and a Level 4 Complete! dialog within 00:00–00:19. The game then offers Next Level. Independently checking the transcribed layout against all four constraints yields the displayed unique solution.
Video publication date is not a claim that today’s build or every device was tested. The video moves on to Level 5 after the completion dialog. Use its opening board when checking the Level 4 answer.
My board is different. What should I do?
Stop using these coordinates. Compare the board size, singleton colors, and region shapes. This page only solves the pictured layout. Return to the deduction guide for a different board.
