About expert suguru
Expert suguru runs on a 12×12 grid with only about 21% of cells given. The cage clusters are tight, and the adjacency constraint web is dense.
Chain reasoning is the primary technique. A placement in one corner of the grid propagates through shared adjacency zones and cage constraints, eventually forcing a placement on the opposite side. You need to trace these chains methodically.
Full candidate lists are mandatory. Work region by region: pick a cluster of intersecting cages, exhaust all eliminations there, then move on. When expert feels manageable, try Einstein puzzles.
How to play Suguru
- Fill every cage with 1 up to its size — a 4-cell cage holds 1, 2, 3, 4.
- A one-cell cage is always 1. A two-cell cage is always 1 and 2.
- No two touching cells may hold the same digit.
- Touching includes diagonals — corners count.
- There are no row or column rules. A digit may repeat in a row, as long as those cells do not touch.
- Every puzzle has one solution, reachable by logic alone.
