1. Click the Play button to begin the game. 

2. Click the Level 1 icon at the bottom of the screen to start the first level. 

3. Click the Fast-Forward button on the bonus screen (you initially will not have any credits to use to buy bonuses). 

4. Click on a pet and drag your mouse over a minimum of three pets of the same type. The pets must be no further than one tile apart from each other. Drag your mouse until you cannot link any more. The more links you make, the more points you score. 

5. For successfully completed levels, you will be rewarded with coins, which you can use to buy additional power-ups if a level proves to be too tricky for you.
