Sudoku Fog:Daily Number Puzzle
TriTail Studio
Sudoku Fog puts a unique twist on the classic number puzzle. The board starts hidden beneath a layer of fog — every cell you solve correctly lifts the mist and reveals what lies beneath.
HOW IT WORKS
• Place the right number → fog lifts from that cell and its neighbours
• The sharper your solve, the more of the board you uncover
• Wrong moves keep the fog in place — no free reveals
• Clear the whole board to lift all the fog and lock in your time
DAILY CHALLENGE
A new puzzle every day at midnight UTC, the same for every player worldwide. Solve it, beat your best time and keep your streak alive. On weekends, take on a special Masterpiece puzzle.
