What Grow Planet F Actually Is
Grow Planet F is a math game on Hooda Math where you answer problems to grow your planet by planting trees. The F version focuses on multiplication facts, specifically the factors and multiples concept. You get a math problem, you type the answer, and if you're right, your planet gets a new tree. Get too many wrong and the planet dies. It's designed for elementary and middle school kids practicing their times tables. The basic loop is straightforward, but there are mechanics that trip people up. The game doesn't always tell you how many mistakes you can afford before losing. You just kind of have to figure it out through trial and error. I found after playing it a dozen times that you're allowed exactly 3 wrong answers per planet. After that, the planet withers. The game never spells this out clearly.
Hooda Math Grow Planet F Walkthrough
Here's how to actually play it well without wasting time. When you start a round, you'll see a blank planet and a math problem at the bottom. These are multiplication problems. You type your answer and hit enter. Correct answers add a tree to the planet. Wrong answers subtract a life counter from the top of the screen. Once lives hit zero, it's game over for that planet. You need to grow the planet to a certain size — typically 10 or so trees — to complete the level. The problems aren't random. They follow a pattern based on the difficulty level you select before starting. Easy mode gives you single-digit multiplication like 3 times 4 or 6 times 7. Medium introduces two-digit by single-digit problems. Hard mode can go up to 12 times 12 or even larger. Pick the level that matches what you're actually studying, not what looks easiest. The easy problems stop being useful for practice once you can answer them without thinking.
One thing most guides miss: the order of questions matters more than you'd think. The game tends to repeat problematic facts until you get them right, then move on. So if you're struggling with 7 times 8, expect to see it come up multiple times in one round. That's by design. Use it. Don't just rush through and click away.

Edge Case That Annoyed Me
I ran into a specific issue where the game would freeze on the answer submission if you typed too fast. Not often, maybe one in every twenty rounds, but it happens. What I did was pause for a full second after typing and before pressing enter. Slowing down your input by just half a second seems to prevent the submission bug. It's not documented anywhere. I discovered it by accident after complaining about a frozen round and noticing my next three attempts didn't freeze when I slowed down. Grow Planet F is decent for rapid-fire multiplication drill. The visual reward of watching your planet grow is a small motivator. It works better than flashcard apps for some kids because it feels like a game, not homework. But it has real limitations. The question bank is finite. If you keep playing the same difficulty, you'll start seeing the same problems repeatedly after about ten rounds. The game doesn't track progress across sessions, so each new round resets everything. There's no persistent leaderboard, no unlockable content, no longer-term engagement. It's a drill tool, not a curriculum. If your kid needs to learn the 9 times table and this game keeps giving them 7s and 8s, you're going to get frustrated fast.
A better approach is to pair it with something like Times Tables Rock Stars or even just a printed multiplication chart. Use Grow Planet F for warm-up practice before a quiz, not as the sole source of math fact fluency.
Practical Tips
Don't play at the hardest difficulty until you've mastered the medium one. The jump from 6 times 7 to 11 times 9 is significant and the pressure of losing planets makes it harder to think clearly. If you miss a problem, don't just stare at the screen. Write the correct answer down somewhere. That's the one your brain got wrong, and it's the one you'll need to remember for a test. The game runs in any browser. No download required. Just go to hoodamath.com and search for Grow Planet F. It's free with optional ads. No account needed.
