Medium 6×6 cage-sum puzzle #48.

Puzzle signature

Medium profile: 15 cages · 8 distinct cage totals · target range 3–13 · 9 two-cell cages · logic score 121. Use this profile as a quick map of the board's strongest cage constraints before you replay the round.

Puzzle analysis

This PUZRU archive puzzle uses 15 connected sum cages across a 6×6 grid with 6 carried fixed values. Its cage profile contains 9 two-cell, 6 three-cell and 0 four-cell cages. Target sums range from 3 to 13, with an average cage target of 8.4.

The generator assigned a logic score of 121, which PUZRU classifies as Medium. The archived quality record verifies one exact solution and a logical solve path without random guessing.

What makes this round distinct

This board combines 8 distinct cage totals. It contains 4 low-target cages (5 or below) and 0 high-target cages (18 or above), creating a round-specific balance between constrained low combinations and high-digit pressure. Its 9 two-cell cages create especially short candidate lists that interact tightly with row and column exclusions.

Logical deduction trace

1. R1C3 starts fixed at 2 from the Chain carry.
2. R2C4 starts fixed at 2 from the Chain carry.
3. R3C5 starts fixed at 1 from the Chain carry.
4. R4C2 starts fixed at 4 from the Chain carry.
5. R5C6 starts fixed at 5 from the Chain carry.
6. R6C1 starts fixed at 2 from the Chain carry.
7. Cage R4C3, R5C3 totals 10; this removes 1/3/5 from R4C3.
8. Cage R4C3, R5C3 totals 10; this removes 1/3/6 from R5C3.
9. Cage R3C4, R4C4 totals 5; this removes 3/5/6 from R3C4.
10. Cage R3C4, R4C4 totals 5; this removes 3/5/6 from R4C4.
11. Cage R5C4, R5C5, R5C6 totals 13; this removes 1/3/4 from R5C4.
12. Cage R5C4, R5C5, R5C6 totals 13; this removes 3/4/6 from R5C5.
13. Cage R6C5, R6C6 totals 9; this removes 4 from R6C5.
14. Cage R6C5, R6C6 totals 9; this removes 1 from R6C6.
15. Cage R3C1, R4C1, R4C2 totals 12; this removes 4/6 from R3C1.
16. Cage R3C1, R4C1, R4C2 totals 12; this removes 1/6 from R4C1.
17. Cage R1C1, R2C1 totals 10; this removes 1/3/5 from R1C1.
18. Cage R1C1, R2C1 totals 10; this removes 1/3/5 from R2C1.
19. Cage R1C5, R1C6, R2C6 totals 8; this removes 5/6 from R1C5.
20. Cage R1C5, R1C6, R2C6 totals 8; this removes 6 from R1C6.
21. Cage R1C5, R1C6, R2C6 totals 8; this removes 6 from R2C6.
22. Cage R2C5, R3C5, R4C5 totals 10; this removes 5 from R2C5.
23. Cage R2C5, R3C5, R4C5 totals 10; this removes 2 from R4C5.
24. Cage R3C6, R4C6 totals 8; this removes 3/4 from R3C6.

How to approach this 6×6 puzzle

• Start with the two-cell cages: their shorter combination lists make them efficient places to eliminate candidates against row and column restrictions.
• Low-total cages are equally useful: only a small set of digit combinations can reach those sums without repeats elsewhere in the grid.
• After every cage deduction, scan both the row and the column before committing a value. PUZRU puzzles are designed so cage arithmetic and Latin-square constraints reinforce each other.

The live result

ARNATUILE became the Discoverer by submitting the first verified solution accepted by the global authority. After that moment, the shared 45-second contribution window remained open and the puzzle finished with 2 verified solvers.

Six values continued into the Chain

The PUZRU world never resets to a completely unrelated board. Six solved positions from this puzzle were carried into the next puzzle as fixed values. For Puzzle #48, the carried values were 6 5 4 3 4 4.

This carry rule makes every puzzle both a standalone logic challenge and one link in an ongoing global sequence.

Chain proof

The public archive records the completed puzzle and its cryptographic Chain hash so later rounds can be linked back to the same history.
