Pet Rescue Saga Level 506
Target: Save 6 pets
Use the paint cans to help you clear the blocks so that the metal boxes will slide out and move to the left side of the board.
Also use paint to gain points (with large groups of blocks) for building up rockets.
As you move down the board try to get the metal boxes (that you’ve not already got with a rocket,) to slide into the far left column where you can use a rocket to eliminate them all.
Try to save at least one spring (line blaster) for the bottom rows.
You also need to make sure you have a rocket left to get the final metal box, which is in the very bottom row.
