How to play
A step up from mini Sudoku. Fill the 6×6 grid so every row, column and 2×3 box contains the numbers 1 through 6, each exactly once.
Rules
- Click an empty cell, then click a number below (or type it) to fill it in.
- Every row, every column, and every 2×3 box must contain each of 1–6 exactly once — a repeated number in that row, column or box is shown in red.
- Arrow keys move the selected cell; Backspace, Delete or 0 clears it.
- Fill in every cell correctly to solve the puzzle — pick a difficulty and press "New puzzle" any time for a fresh one.
Tips
The 2×3 boxes are wider than tall — remember they still only need each number once, same as any row or column.
