• Rock puzzle levels (10, 15, 20 and so on) don’t have a time limit. Take your time and think carefully about each action you take. You can’t collect more mutants by replaying Rock Puzzle levels. You already know the solution, that wouldn’t be fair!
• Visit the farm often to re-activate and upgrade your machines to earn more goo. If you run out of goo, replay previous levels to collect more coins and mutants.
• In the farm, upgrade the machines as often as you can. It’s best to upgrade to the machine that currently holds the greatest number of mutants.
• Don’t panic if the mutants almost block a lane and you think you’re about to lose — you can get out of most sticky situations with some quick thinking and fast reflexes.
• If one lane is filling up and you’re about to lose, put your finger on the lane’s exit point and you’ll automatically catch any animal that comes out.
