Check out the previous puzzle:
Fog Board Game
This is a Sudoku interpretation of the Board Game Ludo.
Normal Sudoku rules apply.
The small numbered coloured squares are Quadruples where the number in the square has to be assigned to one of the surrounding cells.
The Round coloured tokens must contain odd numbers.
Cells connected by a pink Renban line form a set of consecutive digits, in any order, without repeats.
Adjacent digits along an green German Whisper line must differ by at least 5.
Adjacent digits along an orange Dutch Whisper line must differ by at least 4.
Cells joined by an X sum to 10. Cells joined by a V sum to 5.
Digits joined by a white dot are consecutive. Cells joined by a black dot, one digit is double the other.
Not all Xs, Vs or dots are given.
Parts of the board are covered in fog. Placing the correct digits in all the revealed cells will lift more fog and reveal other cells.
FYI - NOT REQUIRED FOR SOLVING THE PUZZLE
Board Layout: The home yard area for each player - initially shown with no tokens - Grid Boxes 1, 3, 9 and 7. The starting square for each player - Blue R6C9, Red R9C4, Green R4C1 and Yellow R1C6. Playing spaces - the outer orthogonally connected cells of Grid boxes 2, 6, 8 and 4 cutting diagonally missing the 4 corner Grid box 5 cells. The Players Home column - coloured cells in R5 and C5 of Grid boxes 2, 6, 8 and 4. The Finishing Square - Grid box 5 cells 2, 6, 8 and 4.
A simplified board and set of Ludo rules - no six to start, no blocking and no returning to home yard.
The completed revealed board is a snapshot of the 1st and 7th moves for 1 token of each player.

Clarified that Board Layout info is not required for solving puzzle.

No idea, what do you do after solving 9x9 internal square, finding one digit revealing outer circle and then nothing happens?
pagedo: @Maciej - Solving the initial 4 boxes will reveal parts of the board after Move 1. Solving those new revealed cells, which will require solving and identifying candidates for other fog cells, will lift all the fog and reveal the whole board.
The outside border cells are not part of the solving - just a visualisation of what dice values were thrown for the advancement of the tokens. When you complete the correct solve of all the internal 9x9 cells, the solution correct message will appear. If that does not happen use the SudokuPad solution check (the tick) and undo functions. New revealed cells will only happen when the current revealed cells are all correct.

It's a very good puzzle, very interesting, and progresses step by step. Especially when the fog clears, the visual impact is excellent.

Nice puzzle, but I wish I'd known that I didn't have to spend time internalizing Ludo rules to solve it. I kept re-reading the board layout section, but couldn't make heads or tails of it.

OK i didnt know how to solve the 4 > 8,9 other than FAR lookahead which basically felt guessing, am i missing something?
pagedo: @_odinh - I assume you are talking about the 4 on the Dutch Whisper next to the 89 candidates. Pencil marking and resolving foggy grid boxes 2, 4, 6 and 8 will resolve that cell.

I enjoyed the previous rendition of a board game more than this cause I’m not familiar with Ludo and it felt like it jumped to the end kinda fast. There was more steps in the other one.

A fog picture puzzle, it seems! I don't know what Ludo is, but it seems I don't need to in order to solve this with ease.

sadly no deductions using ludo mechanics were required to solve this. very pretty puzzle

Nice work, well done. I love it if a suduko tells a story. Sadly this story didn't contribute to the solving of the puzzle. But who cares? :-)
