![]() This explains the elimination of digit 2 from r4c5. Hence any cell that is seen by some green cell and some brown cell cannot contain the digit 2. This implies that the blue cells and the purple cells cannot both contain the digit 2, which means that either the green cells or the brown cells contain the digit 2. To solve these Color Sudoku Puzzles, kids will need to use all four colors - red, blue, green and yellow, only once in each column, row and the block. The second example below looks at the candidates for digit 2.Ī blue cell (r1c1) of cluster #1 sees a purple cell (r1c4) of cluster #2. Hence, the digit 8 can be placed in all the green cells. Since either the brown cells or the purple cells must contain the digit 8, it follows that the digit 8 can be eliminated from all the blue cells. Observe that a blue cell (r3c2) of cluster #1 sees a brown cell (r5c2) of cluster #2, and another blue cell (r2c4) sees a purple cell (r5c4) from cluster #2. The first example below looks at the candidates for digit 8. Multi-Colors have the same power as X-Chains. Another name for a move of this type is Color Wing. Any candidate which can see both of them can now be eliminated. As a result, either B or D must be true, but they could also both be true. There are 2 conjugate pairs: A-B and C-D. Another way to say it is that a bridge connects these clusters. In chaining terms, we say that there is a weak link between these candidates. In coloring terms, we say that these colors are mutually exclusive. And finally choose the options: print or not the solutions. #COLOR SUDOKU ONLINE PDF#Then choose the print format: PDF or HTML. For 9x9 sudoku you can choose to print 4 sudoku per page or 6 sudoku per page. This sudoku and puzzle app was created by Sven Neumann. Then select the level of difficulty: easy, medium, hard, expert, evil. When 2 candidates in 2 clusters are peers, they cannot both be true at the same time. Start by choosing the type of sudoku you want to print: 9x9 sudoku, 4x4 sudoku or 6圆 sudoku. It is not sensible to start all over again for MC. ![]() If a move is discovered that requires only a single cluster, then we call it Simple Colors, otherwise we call it Multi-Colors. Most players just start coloring to see what it may yield. However, it is not fundamentally different from Simple Colors. ![]() The colors represent the parity of the candidates in the cluster. Each cluster must only contain conjugate pairs and has therefore only 2 colors. When a candidate belongs to multiple conjugate pairs, all the candidates it is linked to will have the same color, which is the opposite color to that of the candidate itself. The player first chooses a digit, locates all the conjugate pairs in the grid and starts coloring them. Multi-Colors Multi-Colors is a subtype of coloring that uses more than 2 colors, as opposed to Simple Colors. ![]()
