Prodigy Math and 99math are both math games for children, but they play very different roles. Prodigy is an adaptive game for grades 1 to 8 where a child plays as a wizard, answers questions at their own level, and earns pets and gear. 99math is a free live multiplayer math game for class where a child races against classmates in a short live game, answering questions as fast as they can. If your child needs to learn new math ideas and practise at their own pace, Prodigy is the pick. If your child needs a fun live game for the whole class, 99math is the pick.
What each one is
Prodigy Math is a role playing game. Children play as a wizard, explore a fantasy world, and answer math questions to win battles and earn pets and gear. The questions adapt to the child level and cover the full curriculum, from counting and place value to fractions and algebra basics. A teacher or parent can set which topics appear, and a free teacher dashboard shows how each child is doing. The game is free to play, with an optional parent membership for extra game items.
99math is a live multiplayer math game. A teacher starts a game, the class joins with a code, and each student answers the same set of questions as fast as they can. The class sees a live leaderboard, and the game ends in a few minutes. The program is free, with a paid premium for extra features, and it works in the classroom and at home. The full introduction is in What is 99math.
How they practise math
Prodigy practises math inside a game. A question appears as part of a battle, the child answers, and a correct answer casts a spell. The game adjusts difficulty as the child plays, so a struggling child gets easier questions and a strong child gets harder ones. The practice feels like play, which is why reluctant students often do more of it, and the questions cover new topics, not just facts.
99math practises math as a live race. A child answers questions against the clock, and the leaderboard shows who is fastest. The game is short and exciting, and it works best for facts and quick practice, not for learning a new idea. A child who is slow will see the leaderboard move past them, which can be fun or stressful, depending on the child.
Cost compared

Both tools are free, and neither needs a payment to do its main job. The difference is what the free version covers: Prodigy free version is a full game with adaptive questions, while 99math free version is a live multiplayer game for the whole class.
Grades and ages
The grade ranges are the same, grades 1 to 8, and that is where the choice matters most. 99math covers grades 1 to 8 and is strongest in grades 1 to 6, when children are learning their facts and a live game is exciting. Prodigy covers grades 1 to 8 and is strongest across the whole range because it teaches topics with adaptive questions. A 1st grader starting out will get more from Prodigy, and the grade guides on this site show what it covers at that level, for example Prodigy Math for Grade 1. A 4th grader who knows the ideas but is slow on multiplication facts should use 99math for a few minutes a day on top of Prodigy.
In the classroom
Teachers use the two tools for different moments. Prodigy works as a station activity, a warm up, or daily practice: the teacher sets a topic, each student practises at their own level, and the dashboard shows who needs help. 99math works as a live game: the teacher starts a game, the class joins, and the whole class practises together in a few minutes. It is easy to run because the game is short, and the teacher can see which facts each student has mastered. In class, the two tools do not compete: Prodigy teaches the topics, 99math keeps the practice fun and fast, as shown in Prodigy Math vs ST Math.
For homework and home practice
At home, the difference is motivation. A child will often open Prodigy without being asked, because it is a game with a world to explore, and a session can run for half an hour. 99math at home is a short game: the child does it because a parent asks, and it takes only a few minutes. That is its strength: it is easy to fit in every day. If the goal is practice that happens on its own, Prodigy wins. If the goal is a quick live game that the whole family can join, 99math wins.
Which one should you pick
Pick 99math if the child is in grades 1 to 6, if they know the math ideas but are slow or unsure on the facts, or if you want a live game for the whole class. Pick Prodigy if the child needs to learn new topics, if they avoid math practice, or if a teacher needs to track progress across the curriculum. In the overlap years, grades 1 to 8, use both: 99math for a few minutes of live practice, then Prodigy for the main practice. Neither tool teaches a brand new concept well on its own, so pair either one with a teacher, a video lesson, or a parent explaining the idea first.
