Pet Rescue Saga Level 502 Tips
Your first task should be to release and use the key. After that try to use the boosters of the level (paint brush boosters and line blasters) with wisdom to rescue the demanded number of pets in the 40 moves. Just an advice: Keep clearing blocks in the middle of the screen in order the new pets to come above the screen from there and not from the first or the last column.
