Easy Sudoku
Hints that explain • Daily • Killer
Easy Sudoku is sudoku that teaches as you play. Every puzzle has one answer that you can always reach by logic, and when you are stuck, a hint shows you the next step and why it works — "In the top-left box, 7 fits in only one square" — with the squares that prove it lit up on the board.
Levels mean something here: Beginner and Easy are solved with the two simplest steps alone, Medium adds one more, and Hard brings pairs, triples and the X-Wing. There is also a gentle Mini 6×6, and Killer Sudoku in three levels.
One Easy Daily puzzle every day, the same board for every player, with a streak for solving on consecutive days. Big numbers by default, light and dark themes, notes that tidy themselves and unlimited undo. Works offline, with no account.

What's inside
A hint is a reason, not just an answer
Ask for a hint and Easy Sudoku finds the plainest next step on the board, names it in words and lights up the row, column or box it comes from. If a number you wrote is wrong, the hint points to it first. Harder boards name the harder steps too.
Levels graded by the steps they need
Every board is checked by a solver that thinks like a person before you see it. Beginner and Easy never need more than the only number that fits a square or the only square left for a number — and no level ever needs a guess.
A Daily, Killer and big numbers
The Daily puzzle is the same for everyone, with a streak and a result to share. Killer Sudoku lists the sets of numbers that can still make a cage's total. Numbers are large by default, with an Extra large size and a dark theme.
