Progressive solving hints
These are original Crafty Puzzles hints based on the published objective and mechanism. They do not reproduce the manufacturer's challenge booklet or solution diagrams.
Hint 1
Start with the largest or smallest number constraints because they usually allow fewer combinations.
Hint 2
Use intersections: satisfying one number changes the possibilities for neighbouring numbers.
Hint 3
When stuck, move a tile at a highly connected junction rather than adjusting an isolated triangle.
Background
Recent Toys describes Icosoku as an icosahedral puzzle with repeatable challenges generated by changing the number-tile positions.
