About expert suguru

Expert suguru runs on a 12×12 grid with only 15% 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.
