Pet Rescue Level 338 Tips
Start clearing the blocks of the level, trying not to use the half blasters. Release the pets from their pet boxes where possible, as the screen moves on. Use the half blasters only when there is no other move to do. But if you use them all, before reach the final phase of the level, you eliminate the possibilities of completing it. The difficult part of pet rescue #338 is exactly that, not to lose any pet, staying out of moves.
