## What is Foamula?

Two rows of numbers. One rule turns the first into the second. Find it, build it from bubbles, and do it in as few moves as you can.

Every Foamula puzzle gives you a row IN and a row GOAL. Drag numbers, signs and i into the row to build a formula. YOURS shows what your formula gives, live, cell by cell. When every cell turns green, the pattern is found. Fewer moves earn more stars.

WHAT IS INSIDE
• A daily puzzle: a new one every day, the same one for everyone. Share your result without giving the answer away.
• The ladder: 21 steps that teach every trick, from a single sign to brackets and a second i.
• Practice: 500 puzzles in five weights, from Gentle to Brutal.
• Every puzzle has a proven best number of moves. Match it to earn all three stars.

FAIR AND QUIET
• No account. Your progress stays on your iPhone.
• Free. Stuck? Watch a short clip and the game shows you the formula. Clips play only when you ask for one.
• Works offline, except for hint clips.
