# How to Play Ripple Effect

A Ripple Effect grid is made up of different coloured 'Sets', each consisting of one or more cells. To solve the puzzle, the correct numbers must be placed in each of the cells according to the following rules:

• Every Set must contain the number 1 and then up to the amount of individual cells. For example, if there are four cells in a Set, it must contain the numbers 1, 2, 3 and 4.
• If a row or column includes two identical numbers, at least that number of cells must separate them. For example, two 'number 3' cells in the same row and column must have three cells in between them containing other numbers.

Use the mouse to click up (or down) through the numbers 1 to 9 in each cell. The small black arrows on each side of the cell 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 below the line at the top of each cell.

When you have correctly completed a Set of cells, that area fills with colour and any practice numbers will disappear.
