6ร6 Picross Online โ 36 Cells, Six Difficulty Levels
Six rows, six columns, 36 cells. The 6ร6 format sits one step above the smallest grid on the platform and one step below where multi-line complexity begins to feel genuinely demanding. Pick your difficulty and start.
Choose Your 6ร6 Difficulty
โ 6ร6 Easy โ zero-slack clues dominate, solves in 3โ6 minutes
โ 6ร6 Medium โ multi-block clues, four to six cross-referencing passes
โ 6ร6 Hard โ full arrangement enumeration across 12 lines
โ 6ร6 Expert โ hypothesis technique in a 36-cell network
โ 6ร6 Extreme โ extended multi-cycle hypothesis solving
โ 6ร6 Evil โ nested hypothesis chains at maximum 6ร6 difficulty
Why 6ร6 Is Worth Its Own Space
The natural step from 5ร5. Players who can solve 5ร5 Easy reliably will find 6ร6 Easy a smooth and satisfying progression. Twelve lines instead of ten, 36 cells instead of 25 โ enough additional complexity to feel like a genuine step up without the technique demands that enter at 8ร8.
A richer constraint network. At 6ร6, the 12-line network starts producing more interesting cross-referencing scenarios than 5ร5. A clue of "3" in a 6-cell line โ common at Medium and Hard โ produces zero direct overlap on its own, meaning progress on that line depends entirely on what the perpendicular lines provide. This dependency is a core feature of intermediate Picross and 6ร6 is the first size where it appears regularly.
A practical daily format. Easy and Medium 6ร6 puzzles fall in the five-to-twelve-minute range โ long enough to feel like a complete solving experience, short enough to fit comfortably into a break or a session opener before larger puzzles.
6ร6 Overlap Analysis โ Key Numbers
With a 6-cell line, these overlap results matter most:
Clue "6" โ full line filled immediately. Zero slack.
Clue "5" โ slack 1 โ cells 2โ5 always filled. Four confirmed cells.
Clue "4" โ slack 2 โ cells 3โ4 always filled. Two confirmed cells.
Clue "3" โ slack 3 โ zero overlap. Cross-referenced data from perpendicular lines required before any cells can be confirmed.
Clue "4 1" โ minimum span 6, slack 0. Forced: cells 1โ4 filled, cell 5 empty, cell 6 filled.
Clue "3 2" โ minimum span 6, slack 0. Forced: cells 1โ3 filled, cell 4 empty, cells 5โ6 filled.
Clue "2 3" โ minimum span 6, slack 0. Forced: cells 1โ2 filled, cell 3 empty, cells 4โ6 filled.
Where 6ร6 Sits in the Full Progression
6ร6 is the second smallest Picross format on the platform. Players working through the full size progression typically use it as a bridge:
Coming from 5ร5, the extra two lines and eleven cells introduce new overlap patterns and a larger cross-referencing network without demanding techniques beyond what 5ร5 has already taught.
Moving toward 8ร8 Picross, the 16-line network at 8ร8 requires tracking significantly more constraint interactions simultaneously โ 6ร6 is the last size where the full grid state remains easy to hold in mind without any written notation.

FAQ
Both are good starting points, but 5ร5 is slightly more recommended for complete beginners. The overlap patterns on 5ร5 Easy are more immediate and produce faster feedback on whether your technique is correct. If you've already tried 5ร5 Easy and it felt comfortable, 6ร6 Easy is the right next step.
The difficulty increase is moderate at Easy and Medium โ more passes are required, and some clue types (particularly single "3" clues) produce no direct overlap and require cross-referencing from the start. At Hard through Evil, the additional two lines and eleven cells extend the hypothesis cycles but don't change the technique. The increase feels more significant at lower difficulties than at higher ones.
At 36-cell resolution, images are still relatively abstract โ more suggestive than detailed. The reveal is cleaner than at 5ร5 and shapes are more recognizable, but the detailed pixel art that makes Picross visually compelling starts appearing at 8ร8 and becomes genuinely expressive at 10ร10 and above.
Easy: 3โ6 minutes. Medium: 6โ12 minutes. Hard: 10โ18 minutes. Expert: 14โ25 minutes. Extreme: 20โ32 minutes. Evil: 25โ40 minutes. These ranges reflect solvers with solid technique at the relevant difficulty level.
