How to play

Goal: Fill all 81 cells with numbers from 1 to 9 so that each row, column, and 3x3 block contains each digit exactly once. Basics: Click on an empty cell, then select a number on the panel at the bottom. To erase it, press "⌫". If a number conflicts with another one, the cell will be highlighted in red (with verification enabled). Pencil: Turn on the pencil mode to write down the candidates — several small numbers in one cell. Pressing it again removes the mark. This is how difficult puzzles are solved! Control: "↶" — cancel the move, "↷" — repeat. The "new Game" is a fresh puzzle game. Settings (☰): choose difficulty (Easy / Medium/Difficult), turn on or off the conflict checker and timer. Play at your own pace — with no time limits!
