To solve a ShapeShifter, every number from 1 to 9 must appear in:

• Each of the nine vertical columns
• Each of the nine horizontal rows
• Each of the nine blocks of same-coloured squares

Use the mouse to click up (or down) through the numbers 1 to 9 in each square. The small black arrows on each side of the square tell you whether you are counting from 1 up to 9 (right arrow) or from 9 down to 1 (left arrow).

Using your keyboard, you can type in up to eight practice numbers above the line at the top of each box.

Cross-hatching shows you have correctly completed a row, column or group of nine same-coloured squares. Any practice numbers disappear.
