This document summarizes the solution to a Diabolic Str8ts puzzle. It begins by describing the starting position and notes that ordinary strategies are not enough. It then outlines the steps taken, including applying Setti's rule on digits like 7 and 8, using techniques like X-wing and naked triples. Testing different possibilities leads to deducing values like J3=6 and eventually the full solution. Key links between cells are discovered and tested throughout the solving process.
