What your child actually does
Spell to survive
In Story Mode the ship's supplies are tied to subjects: spelling refills water, math refills food, science refills oxygen. Spell the word right and the crew keeps flying.
Hear every word
The game speaks each word aloud, in a sentence, and there is a 🔊 button to hear it again. Kids who are not reading fluently yet can still play.
Explore, then practice
World Mode is a 3D open world: fly the family ship between planets, walk around the Earth home base, and play arcade mini-games like Cosmic Putt-Putt and Star Miner between lessons.
Difficulty that follows the child
Words start at your child's grade and step up as they get answers right. A kid who races ahead keeps getting harder words; a kid who struggles gets more practice.

Questions parents ask
Is Space Force Spelling really free?
Yes. The story, the 3D world, and the arcade are free. There is no ad network in the game. Grown-ups can optionally buy Family Edition ($19.99 once) to put their own family in the game; the free game is never pay-to-win.
Do kids need an account?
No. Kids can start playing as a guest right away and progress saves on that device. A free account is optional and is only for keeping progress across devices and for unlimited play time.
What ages or grades is it for?
The curriculum runs from kindergarten through 6th grade, and the word and question banks stretch into middle-school level for kids who race ahead. There is also a free Baby Mode for preschoolers.
Does it work on a phone or tablet?
Yes. It runs in any modern browser on phones, tablets, Chromebooks and computers, and it can be installed to the home screen so it opens full-screen like an app.
Family Edition: $19.99 once · not a subscription · grown-ups only
Family Edition puts your own crew in the cockpit: a photo or a typed description becomes your family's faces on the cadets' helmets and a story cutscene still. Parents can also paste this week's school spelling list so the game practices exactly those words, set family missions, and print a one-page cadet report.
See Family Edition on the parents pageThe free game never becomes pay-to-win. Teachers: a Classroom edition with rosters and join codes is $79 per 12 months, inside the game.
