Puzzle signature
Hard profile: 13 cages · 8 distinct cage totals · target range 3–18 · 5 two-cell cages · logic score 126. 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 13 connected sum cages across a 6×6 grid with 6 carried fixed values. Its cage profile contains 5 two-cell, 6 three-cell and 2 four-cell cages. Target sums range from 3 to 18, with an average cage target of 9.7.
The generator assigned a logic score of 126, which PUZRU classifies as Hard. 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 2 low-target cages (5 or below) and 1 high-target cage (18 or above), creating a round-specific balance between constrained low combinations and high-digit pressure. Its 5 two-cell cages create especially short candidate lists that interact tightly with row and column exclusions.

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.
- Pay attention to the highest cage totals. In a 1–6 grid, large totals force several high digits and can quickly remove low candidates from those cells.
- Low-total cages are equally useful: only a small set of digit combinations can reach those sums without repeats elsewhere in the grid.

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 #67, the carried values were 3 1 2 1 3 4.
This carry rule makes every puzzle both a standalone logic challenge and one link in an ongoing global sequence.
