Read the grid

Rows run across. Columns run down. The heavier lines mark boxes that are three cells wide and two cells tall.

The numbers already on the board are clues. Leave them in place and use them to work out what can go in each empty cell.

Row

Column

Box

Each highlighted group has six cells and must contain 1 through 6.

Try a move with Juno

Start with a row that’s almost full. Find its missing number, then check that the number is free in the empty cell’s column and box.

“One gap. Count what you have, then check what crosses it.”

1 2 3 4 ? 6 6 1 2 3 4 6 6 1 3 6 4

Which number is missing from 1, 2, 3, 4, blank, 6?

Use Notes to track possibilities

If two numbers could fit, select the empty cell, turn on Notes, and enter both. When another clue rules one out, tap that number again to remove its note. Turn Notes off before entering your answer.

Pencil in 2 and 5. If a clue rules out 2, enter 5 as the answer.

Check duplicates and finish

When two matching numbers share a row, column, or box, the game highlights the conflict in red. Check the surrounding clues to work out which entry to change. A full grid with no duplicates is checked automatically.

Two 4s share this row. Use the clues in their columns and boxes to see where the 4 belongs.
