Prodigy Math is one of the most popular math games in North America. Over 50 million students have used it, and teachers love how easy it is to assign. But if you've spent any time in parent forums or teacher communities lately, you've probably noticed a growing frustration: Prodigy isn't really free anymore.
Technically, students can still answer math questions for free. But the game experience around those questions (the pets, the gear, the member areas) is increasingly locked behind a paid membership. For a lot of kids, that means watching their classmates enjoy content they can't access, which turns what should be a fun math experience into a source of frustration.
That's not the only reason people look for alternatives, though. Here are the most common ones:
Why Parents and Teachers Leave Prodigy
The Paywall Problem
Prodigy's premium membership costs about $9.95 per month or $60 per year. Without it, free players are constantly reminded of what they're missing. Treasure chests they can't open, pets they can't rescue, areas they can't explore. For younger kids especially, this creates a have-vs-have-not dynamic in classrooms that teachers find uncomfortable.
Elementary-Focused Content
Prodigy covers grades 1-8 on paper, but its heart is in elementary math. The game world, the art style, and the difficulty curve are all built around younger students. By 6th or 7th grade, many students find the game babyish. The middle school content exists, but it doesn't feel like it was the priority.
Multiple Choice Only
Every math question in Prodigy is multiple choice. That works for quick checks, but it doesn't build the same depth of understanding as having students actually work through problems. Research consistently shows that constructed response leads to better retention than selected response (picking from options). A student who picks "B" and gets it right may not understand the math at all. They might have just eliminated two wrong answers.
Engagement vs. Learning
Some teachers have noticed that students spend more time in Prodigy managing their pets, decorating houses, and battling friends than actually doing math. The game layer is thick, and the math can feel like a speed bump between the fun parts rather than the point of the experience.
The Best Prodigy Alternatives
Here are the platforms and games that do things differently. Each one addresses at least one of the frustrations above.
1. Infinilearn: Best Overall Alternative
Grades: 6-8 · Price: Completely free · What makes it different: Middle school focus, multiple choice math problems, no paywall
Infinilearn is a fantasy RPG built specifically for middle school math. That focus is its biggest advantage over Prodigy. Instead of trying to cover K-8, Infinilearn goes deep on grades 6-8 content: ratios, proportional relationships, expressions, equations, geometry, statistics, probability, functions, and the Pythagorean theorem.
Students answer multiple choice questions tied to real math problems. When they use a weapon attack in battle, a math problem appears and they pick the correct answer. The game adapts to each student's level, so a struggling 6th grader and an advanced 8th grader both get appropriately challenging content.
The game itself is a proper RPG. Students create a character, explore a world, battle enemies, and progress through a story, all powered by math. But unlike Prodigy, there's no premium tier. Everything in the game is available to every player. No locked pets, no member-only areas, no upselling.
Parents and teachers both get dashboards with detailed analytics. Teachers can see performance by standard, assign the game to a class, and track progress over time. Parents can see what topics their child is working on and where they might need extra help.
2. Khan Academy: Best for Instruction
Grades: K-12+ · Price: Completely free · What makes it different: Video lessons + mastery-based practice
Khan Academy isn't a game, and that's kind of the point. If your student needs to actually learn a concept, not just practice it, Khan Academy is the place to go. The video explanations are clear, the practice problems are scaffolded well, and the whole thing is 100% free thanks to its nonprofit model.
The downside is that it requires more self-direction than Prodigy. A kid who won't open Khan Academy on their own might still play a math game voluntarily. Many families use Khan Academy for learning new concepts and a game like Infinilearn for practice and fluency. The two work well together.
3. Math Playground: Best for Quick Games
Grades: 1-6 · Price: Free (ad-supported) · What makes it different: Hundreds of mini-games, no account required
Math Playground is a collection of small, focused math games. There's no overarching RPG or story. It's just a big library of games organized by topic and grade level. The logic puzzles are especially good, and students can jump in without creating an account.
The limitation is that most content tops out around 6th grade. It's a solid alternative for younger middle schoolers, but 7th and 8th graders will find themselves running out of appropriate content quickly. The site also has ads, though they're not as aggressive as some other platforms.
4. DeltaMath: Best for Teacher-Directed Practice
Grades: Middle school through AP · Price: Free (basic) / paid ($0-$150 school license) · What makes it different: Teacher-assigned problems with worked examples
DeltaMath is a teacher-facing platform where educators create custom problem sets and assign them to students. When a student gets a problem wrong, they can view a worked example before trying again. It's not gamified at all. It's straight math practice, but the problems are well-written and the worked examples are helpful.
The free version is quite generous for individual teachers. It's a strong choice if your priority is specific, targeted practice on exact topics. But students won't choose to use DeltaMath for fun the way they might choose a game.
5. IXL: Best for Comprehensive Coverage
Grades: K-12 · Price: Paid ($9.95/month per subject) · What makes it different: Exhaustive skill coverage with diagnostic tools
IXL isn't free, so it doesn't solve Prodigy's paywall problem. But it's worth mentioning because it's one of the most comprehensive math practice platforms available. Every standard in every grade is covered with dozens of problems. The diagnostic tool identifies gaps and recommends what to practice next.
The experience is not gamified. It's practice problems with a SmartScore system that can actually be stressful for some students (the score goes down when you get problems wrong). If your student is self-motivated and wants exhaustive practice, IXL delivers. If they need engagement to get started, look elsewhere.
6. Desmos Classroom: Best for Conceptual Understanding
Grades: 6-12 · Price: Completely free · What makes it different: Interactive graphing and teacher-led activities
Desmos started as a graphing calculator and has grown into a full classroom activity platform. The activities are beautifully designed, interactive, and build deep conceptual understanding. Students manipulate graphs, explore relationships, and make predictions.
It's not a game and it's not self-directed. A teacher needs to run the activities. But for building understanding of functions, graphing, and algebraic relationships, nothing else comes close. It's also completely free with no premium tier.
7. Quizizz: Best for Classroom Competition
Grades: K-12 · Price: Free (basic) / paid for premium features · What makes it different: Live quiz competitions with memes and power-ups
Quizizz lets teachers create or use pre-made quizzes that students complete in a competitive format. It adds memes, power-ups, and leaderboards to make quizzing more fun. The math content is teacher-created (or pulled from a shared library), so quality varies.
It's more of a formative assessment tool than a learning game, but the competitive format can motivate students who don't respond to traditional practice. The free tier is adequate for most classroom use.
Comparing the Alternatives
Here's how to think about which alternative fits your situation:
- You want a game that replaces Prodigy for middle school: Infinilearn is the most direct replacement. It's a proper RPG, it's completely free, and it's built specifically for grades 6-8.
- You want free instruction, not just practice: Khan Academy is the answer. Pair it with a game for the engagement factor.
- You want teacher control over exactly what students practice: DeltaMath gives teachers the most control over content and sequencing.
- You want quick, casual games for early middle school: Math Playground has the largest variety of mini-games.
- Budget isn't a concern and you want exhaustive practice: IXL covers more individual skills than anything else.
What to Look For in a Math Game
Whatever you choose, here are the things that actually matter:
- Grade-appropriate content. A game that covers K-8 will never be as deep on 7th grade content as one built specifically for middle school.
- Real math problems, not busywork. Look for games where the math questions actually require thinking, not just random guessing. Quality problems build real understanding.
- Adaptive difficulty. A student who keeps getting problems right should get harder ones. A student who's struggling should get scaffolded support, not the same question they already missed.
- Parent or teacher visibility. If you can't see what your student is doing and how they're performing, the game is a black box.
- Actually free means actually free. If core game content is locked behind a paywall, it's not free. It's a free trial.
The best Prodigy alternative depends on what frustrated you about Prodigy in the first place. But if you're looking for a math game that's genuinely free, designed for middle school, and requires students to actually solve problems, Infinilearn checks every box.
