Welcome to the boss level
Expert aims for about 11 given digits. That is enough for one unique solution, but you may need to build a careful candidate map before the first move becomes clear.
Work slowly and trust the groups. Every triangle still belongs to one hexagon and three lines, so even a wide-open board contains lots of hidden information.
Expert checklist
-
Fill all candidates
Start with Auto Notes and inspect every one-candidate triangle.
-
Find hidden singles
Inside each hexagon and line, check whether one digit appears in the notes of only one cell.
-
Find pairs
Two cells with the same two candidates lock those digits into place within their shared group.
-
Recheck four groups
After every placement, revisit its hexagon and three crossing lines.
-
Take a break
Your progress is saved. Fresh eyes are often the best Expert strategy.
