They've hit the ceiling
Every world cleared, level maxed, nothing left to chase. A finished game stops being a reason to do math.
Switching from Prodigy
Finished Prodigy? Here's the next quest.
Infinilearn is a free math RPG built for grades 4-9: the kids who maxed out Prodigy, got bored of it, or aged out of a game made for elementary school. Math still powers every battle. The world, the problems, and the free version all grow up with them.

Is it time?
Six signs your child has outgrown Prodigy.
Prodigy is a good game for young kids, and we say so in our own founder-written comparison. The problem is that kids keep growing and the game doesn't. If two or three of these sound familiar, they're ready for the next step.
The math feels easy
They answer without reading. Misses are careless, not confused. Practice below their level builds speed, not skill.
They're in 4th grade or above
Prodigy lists grades 1-8, but its center of gravity is elementary. Fourth and fifth graders feel the ceiling first.
They call it a little-kid game
Ten-year-olds have sharp detectors for this. Once it fires, no amount of new pets brings the engagement back.
Collecting replaced practicing
More time on pets and gear than on problems. The reward loop is doing the motivating, and the math is along for the ride.
The membership ask wore you down
You'd rather pay for insight into what your child knows than for rewards they can see other kids unlocking.
What changes
Same idea. Built for the next four years instead of the last four.
Both games turn math into battles. The differences are who each one is built for, what the optional subscription buys, and how much game a free player actually gets.
| Feature | Infinilearn | Prodigy Math |
|---|---|---|
| Built for | Grades 4-9, and only those grades | Grades 1-8, elementary-leaning |
| Free version | The whole game: 15 zones, every quest, every boss, every problem | The math, with the best rewards fenced off for members |
| What paying buys | Parent and teacher insight plus cosmetics. Nothing that changes progress. | Pets, gear, and member-only areas, about $9.95 a month |
| How practice adapts | Attacks pull from your child's weakest topics; difficulty rises and falls with their answers, down to Foundations when needed | Adaptive to grade level, with a parent-set grade |
| Answer format | Mostly multiple choice; typed answers on the harder 9th grade problems | Multiple choice and typed |
| Platforms | Any browser, including Chromebooks and iPad Safari. No native app yet. | Browser plus native iOS and Android apps |
| Chat and safety | Preset quick-chat only, no ads, no external links, no selling data | See Prodigy's own parent resources; we won't characterize systems we don't run |
| Parent tools | Free dashboard for one child: accuracy by topic, strengths, weak spots. Premium adds unlimited kids, practice paths, and trends. | Parent dashboard, with more detail for members |

The first week
Ten minutes decide whether they come back. Here's how to win them.
Nothing from Prodigy carries over, which most kids treat as the point: a new world, a new character, a fresh start. The one thing to protect is the first session. A kid who bails on day one is twice as hard to bring back, so stay nearby for the opening battles.
- 1Create a parent account, add your child
Pick the grade they're in right now, 4th through 9th. Or let them sign up as a student and link the accounts later.
- 2The first battles start easy
New players open with the most approachable topics in their grade. Nobody meets two-step equations on question three.
- 3If they wobble, it eases down
A rough stretch drops the game into Foundations practice, real grade 2-3 skills, until confidence is back. Then it climbs.
- 4Check the dashboard after a few sessions
Accuracy by topic, strengths, weak spots, and problems solved. You'll know more about their math in a week than Prodigy told you in a year.
Which grade to pick
Pick the grade they're in, not the grade they test into.
The game adapts inside a grade, so choosing their real grade gives the engine the right target. If your child is in 3rd grade and has genuinely finished Prodigy, you can start them at 4th: Foundations practice will catch a stumble, but expect multi-digit multiplication, fractions, angles, and remainders within the first week. If that's a stretch, Prodigy or another elementary game is the better fit for now, and we'd rather say so than waste your evening.
Outside the US, match by age. Year levels shift a little by state and birthday, so when in doubt, pick by age and adjust from the dashboard later.
| US grade | Age | Australia | England |
|---|---|---|---|
| 4th grade | 9 to 10 | Year 4 | Year 5 |
| 5th grade | 10 to 11 | Year 5 | Year 6 |
| 6th grade | 11 to 12 | Year 6 | Year 7 |
| 7th grade | 12 to 13 | Year 7 | Year 8 |
| 8th grade | 13 to 14 | Year 8 | Year 9 |
| 9th grade | 14 to 15 | Year 9 | Year 10 |
Switching FAQ
The stuff Prodigy parents ask before switching.
Is the whole game free, or is this Prodigy's membership model again?
The entire game is free: every zone, quest, boss, and math problem, with no ads. Premium ($9.99 a month or $59.99 a year) buys parents deeper insight and kids cosmetic extras like hair colors, a custom username, and a pet named Finny. No area unlocks and nobody progresses faster because a parent paid. A free player has the whole game.
Does my child's Prodigy progress carry over?
No. Infinilearn is a different game with its own world and character. The adaptive engine places your child at the right level within their first few battles, so there is nothing to re-earn on the math side, and the new character is usually the part they're excited about.
Which grade should I pick if my child just finished Prodigy?
Pick the grade they are in right now. Infinilearn starts at 4th grade. A strong 3rd grader can start at 4th, and the game will ease down into Foundations practice if the first battles are too hard, but 4th grade content arrives quickly. Below 3rd grade, Prodigy or another elementary game is still the better fit.
What if the first session is too hard and my child quits?
Battles start with the most approachable topics in your child's grade. If they struggle, the game drops into Foundations practice, real grade 2-3 skills, and climbs back up as they answer correctly. Parents can also lower the grade from the dashboard. Sit nearby for the first ten minutes; the first wobble is the moment that decides whether they come back.
Is there an iOS or Android app?
Not yet. Infinilearn runs in any modern browser, including Safari on an iPad, with nothing to install. If you lock devices down with Screen Time, go to Content & Privacy Restrictions, then Content Restrictions, then Web Content, choose Allowed Websites Only, and add infinilearn.com. Your child gets the game and everything else stays locked.
Does Infinilearn work outside the United States?
Yes. It is browser-based and works anywhere. The math is organized by US grade, so pick the grade that matches your child's age using the table above: US 4th grade is roughly Year 4 in Australia and Year 5 in England.
What about younger siblings?
Grade 4 is the floor. For a child in 3rd grade or below, Prodigy or another elementary game is still the better choice, and we say so plainly. Our roundup of games like Prodigy covers the younger options.
Is it safe?
No ads, no external links during play, and no open chat. Multiplayer uses preset quick-chat lines only. We collect only what the game needs to run and never sell student data. The parent guide has the full rundown.
