About SudokuIQ
Built and puzzle-tested by Chamara S. Kodikara
SudokuIQ connects polished browser games, two Android apps, cross-device continuation and a practical learning Academy.
How puzzles are made
Sudoku boards begin with a valid solved grid. Clues are removed according to the selected level, and the generator checks that the published puzzle still has one solution. Difficulty is presented through the same ladder used by the Android experience.
Coaching philosophy
Hints should explain a logical next move instead of replacing thought with a final answer. Notes, candidate removal, boosts and Academy lessons are designed around that principle.
Android connection
The Classic Sudoku and Killer Sudoku apps provide offline play and native phone controls. SudokuIQ’s transfer feature lets players continue supported games on another device.
