MeowBlock! Level 42 Walkthrough
Solve MeowBlock! Level 42 by locking the three lower 7-cell bars, building the left columns, and closing the upper 4/6/4 cluster around the persistent 2x2 remainder.
How to Solve MeowBlock! Level 42 — Full Solution
- Step 1: Anchor r9c8=7; commit r9c3:r9c9 as a 1x7 rectangle with area 7.
- Step 2: Anchor r8c7=7; commit r8c3:r8c9 as a 1x7 rectangle with area 7.
- Step 3: Anchor r7c4=7; commit r7c3:r7c9 as a 1x7 rectangle with area 7.
- Step 4: Anchor r7c1=4; commit r6c1:r9c1 as a 4x1 rectangle with area 4.
- Step 5: Anchor r7c2=5; commit r5c2:r9c2 as a 5x1 rectangle with area 5.
- Step 6: Anchor r4c1=5; commit r1c1:r5c1 as a 5x1 rectangle with area 5.
- Step 7: Anchor r2c2=4; commit r1c2:r4c2 as a 4x1 rectangle with area 4.
- Step 8: Anchor r1c5=7; commit r1c3:r1c9 as a 1x7 rectangle with area 7.
- Step 9: Anchor r2c4=4; commit r2c3:r3c4 as a 2x2 rectangle with area 4.
- Step 10: Anchor r3c7=6; commit r2c5:r3c7 as a 2x3 rectangle with area 6.
- Step 11: Anchor r3c8=4; commit r2c8:r3c9 as a 2x2 rectangle with area 4.
- Step 12: Anchor r4c6=5; commit r4c3:r4c7 as a 1x5 rectangle with area 5.
- Step 13: Anchor r5c4=6; commit r5c3:r6c5 as a 2x3 rectangle with area 6.
- Step 14: Anchor r5c7=4; commit r5c6:r6c7 as a 2x2 rectangle with area 4.

Common Mistakes to Avoid
- Do not keep r2c3:r2c6 for r2c4=4; the persistent shape is the 2x2 r2c3:r3c4.
- Do not read the ringed 3 at r7c1 as an extra clue; r7c1 belongs to the area-4 column r6c1:r9c1.
- Do not merge the three lower 7-cell bars; they occupy rows 7, 8, and 9 separately.
Quick Tips for MeowBlock! Level 42 (spoiler-free)
- Build r7c3:r7c9, r8c3:r8c9, and r9c3:r9c9 as three separate 7-cell bars.
- Keep r1c3:r1c9 distinct from the lower 7-cell rows so the left columns remain open.
- Use r2c3:r3c4 for the upper 4 instead of the tempting horizontal preview.
Board notes 5 details
- Layout
- 9 rows by 9 columns, 81 cells. Clues: r1c5=7, r2c2=4, r2c4=4, r3c7=6, r3c8=4, r4c1=5, r4c6=5, r5c4=6, r5c7=4, r5c8=6, r7c1=4, r7c2=5, r7c4=7, r8c7=7, and r9c8=7. No unknown clues appear. The ringed 3 at r7c1 is a touch overlay; the fixed clue is 4.
- Goal
- Partition all 81 cells into fifteen rectangles in the persistent order: r9c8=7 at r9c3:r9c9 (area 7); r8c7=7 at r8c3:r8c9 (area 7); r7c4=7 at r7c3:r7c9 (area 7); r7c1=4 at r6c1:r9c1 (area 4); r7c2=5 at r5c2:r9c2 (area 5); r4c1=5 at r1c1:r5c1 (area 5); r2c2=4 at r1c2:r4c2 (area 4); r1c5=7 at r1c3:r1c9 (area 7); r2c4=4 at r2c3:r3c4 (area 4); r3c7=6 at r2c5:r3c7 (area 6); r3c8=4 at r2c8:r3c9 (area 4); r4c6=5 at r4c3:r4c7 (area 5); r5c4=6 at r5c3:r6c5 (area 6); r5c7=4 at r5c6:r6c7 (area 4); and r5c8=6 at r4c8:r6c9 (area 6).
- Opening
- The source builds the three lower 7-cell bars first, then the lower-left 4/5 columns and the left area-5 wall. The upper area-4 column and top 7 follow, before the center/right 4/6/4 shapes and the final row-4 and lower 6-cell regions.
- Danger Zone
- Reject the provisional r2c3:r2c6 horizontal area-4 preview for r2c4=4. It captures cells needed by r3c7=6 and strands the r3c4 corner; the persistent rectangle is r2c3:r3c4. The ringed 3 over r7c1 is not a clue.
- Mechanics
- All fifteen fixed integers are rectangle areas summing to 81. Parallel lower bars and short touch overlays make release state important; the final colored board and Perfect frame confirm the persistent exact cover.
Frequently Asked Questions
What is the correct area-4 shape for r2c4=4?
It is the 2x2 rectangle r2c3:r3c4, not the transient r2c3:r2c6 strip.
Is the ringed 3 at r7c1 a fixed clue?
No. It is a touch overlay; the fixed clue is r7c1=4 and its region is r6c1:r9c1.
How many rectangles solve Level 42?
Fifteen persistent rectangles cover all 81 cells in the 9x9 solution.
