Meowdoku Level 851 Step-by-Step Logic Walkthrough & Explained
Follow the replay below. Each board shows the result after applying that step.
Meowdoku Level 851 Step 1: Mark X at R3 C4, R3 C5, and R5 C4 + 2 more: rows or columns are reserved
The rose, sky blue, green, and purple regions must use columns 4, 5, 6, and 7. No other region can use those columns. Mark the highlighted cells with X.
Meowdoku Level 851 Step 2: Mark X at R2 C2 and R4 C3: cats cannot touch
Every possible cat for the yellow region conflicts with these cells. Cats cannot share a row, column, region, or diagonal touch. Mark the highlighted cells with X.
Meowdoku Level 851 Step 3: Mark X at R4 C6: cats cannot touch
Every possible cat for the green region conflicts with these cells. Cats cannot share a row, column, region, or diagonal touch. Mark the highlighted cells with X.
Meowdoku Level 851 Step 4: Mark X at R2 C7: cats cannot touch
Every possible cat for the sky blue region conflicts with these cells. Cats cannot share a row, column, region, or diagonal touch. Mark the highlighted cells with X.
Meowdoku Level 851 Step 5: Mark X at R6 C6: cats cannot touch
Every possible cat for the purple region conflicts with these cells. Cats cannot share a row, column, region, or diagonal touch. Mark the highlighted cells with X.
Meowdoku Level 851 Step 6: Mark X at R1 C5: assuming a cat there leaves a region empty
Suppose held a cat in the rose region. That assumption would leave the yellow region with no legal cell left. So cannot contain a cat. Mark it with X.
Try a temporary cat at , then follow what the puzzle rules force. If it leads to a contradiction, the must be X in the real puzzle.
Meowdoku Level 851 Step 7: Mark X at R1 C6: assuming a cat there leaves a region empty
Suppose held a cat in the rose region. That assumption would leave the yellow region with no legal cell left. So cannot contain a cat. Mark it with X.
Try a temporary cat at , then follow what the puzzle rules force. If it leads to a contradiction, the must be X in the real puzzle.
Meowdoku Level 851 Step 8: Mark X at R1 C7: assuming a cat there leaves a region empty
Suppose held a cat in the rose region. That assumption would leave Column 4 with no legal cell left. So cannot contain a cat. Mark it with X.
Try a temporary cat at , then follow what the puzzle rules force. If it leads to a contradiction, the must be X in the real puzzle.
Meowdoku Level 851 Step 9: Mark X at R2 C3: cats cannot touch
Every possible cat for the rose region conflicts with these cells. Cats cannot share a row, column, region, or diagonal touch. Mark the highlighted cells with X.
Meowdoku Level 851 Step 10: Mark X at R2 C4: assuming a cat there leaves a region empty
Suppose held a cat in the rose region. That assumption would leave the green region with no legal cell left. So cannot contain a cat. Mark it with X.
Try a temporary cat at , then follow what the puzzle rules force. If it leads to a contradiction, the must be X in the real puzzle.
Meowdoku Level 851 Step 11: Mark X at R2 C5: assuming a cat there leaves a region empty
Suppose held a cat in the rose region. That assumption would leave the yellow region with no legal cell left. So cannot contain a cat. Mark it with X.
Try a temporary cat at , then follow what the puzzle rules force. If it leads to a contradiction, the must be X in the real puzzle.
Meowdoku Level 851 Step 12: Mark X at R2 C6: assuming a cat there leaves a region empty
Suppose held a cat in the rose region. That assumption would leave Column 4 with no legal cell left. So cannot contain a cat. Mark it with X.
Try a temporary cat at , then follow what the puzzle rules force. If it leads to a contradiction, the must be X in the real puzzle.
Meowdoku Level 851 Step 13: Place cat at R1 C4: only legal cell
Place a cat here at . The rose region has no other legal cell.
Meowdoku Level 851 Step 14: Place cat at R2 C1: only legal cell
Place a cat here at . Row 2 has no other legal cell.
Meowdoku Level 851 Step 15: Place cat at R3 C3: only legal cell
Place a cat here at . The yellow region has no other legal cell.
Meowdoku Level 851 Step 16: Place cat at R4 C7: only legal cell

Meowdoku Level 851 Step 17: Place cat at R5 C5: only legal cell
Place a cat here at . The green region has no other legal cell.
Meowdoku Level 851 Step 18: Place cat at R7 C6: only legal cell
Place a cat here at . The purple region has no other legal cell.
Meowdoku Level 851 Step 19: Place cat at R6 C2: only legal cell
Place a cat here at . The brown region has no other legal cell.
