Pet Rescue Saga Level 420
Target: Save 6 pets
Start clearing in the middle columns of the level, try to completely remove a column.
Then move to the top and get some pets to drop.
Drop the pets down the centre of the game.
Use a hammer, or by matching a block with a pet carrier to break the diagonal pattern of the blocks bottom right, drop them then clear with the line blasters (springs)
Get the pets to the bottom rows in the middle of the game and drop bombs to blow up both them and the metal blocks that fall.
Don’t bother freeing the pets first, as the bombs will let them out.
