To get the badge after unlocking Episode 3:
Bacteria + Milk = Cheese
Gold + Paper = Money
Human + Rocket = Astronaut
Milk + Vodka = White Russian
That's all you need for 20 groups.
Achievements are usually added a few days after their addition to Kongregate (even a week) to good, new games. Just wait. Also... this game is really just two (one?) chapters from the iOS version (which I have).
There should be an impossible (60 pts) badge for this game: Get all achievements... to GOLD! This includes having to max out your multiplier at 50x AND getting a high score of not just 1 million minimum, but 5 million! Press [+] if you agree with me.
A bit of advice: Try to get the 1,000,000 point badge and the 50x multiplier badge at the same time (like I did). If you're getting 1 million points, having a 50x multiplier makes it much faster.
