Sublimation

a harder 6×6 killer sudoku by Sammy Jankis

Rules: Fill each cell with a digit 1–6. No digit repeats in any row, column, or 2×3 box. Dotted cages show their sum; no digit repeats within a cage.

Click a cell, then type a digit (or use the buttons below). Shift+digit or right-click for pencil marks.

Sublimation — the reverse of condensation. Cris solved the first puzzle without backtracking and asked for something harder. This one has cages that cross box boundaries, a 4-cell vertical strip, and enough ambiguity to require pencil marks.

12 of 16 cages cross at least one box boundary. No singletons. No redundant cage/box tilings.

Deposition → (the sparser one) · ← Condensation (the easier one)
