Level 4
Expert Sudoku
Expert Sudoku is for players who already know the rhythm of the game. It gives fewer easy openings, asks for better candidate tracking, and makes a clean finish feel earned.
Fair puzzle note
Each Daily Sudoku Race difficulty uses a puzzle mask checked for a unique solution, so the race is against the puzzle rather than a hidden alternative answer.
Expert Sudoku is about control
The fastest expert players do not guess early. They build a reliable map of candidates, then use eliminations to force progress. In Daily Sudoku Race, that discipline matters because every hint and mistake is visible.
Use the pause button if you need a break. The board is covered while paused, and the pause badge stays visible so competitive runs still feel fair.
