99math does exactly one job, and it does it brilliantly. A teacher picks a skill, starts a live round, students join from any device, and thirty seconds later the whole room is racing through arithmetic. It's free, it takes zero prep, and the energy is real. If you're running it as a fact-fluency warm-up, you should keep running it.
But teachers usually search for "games like 99math" for one of two reasons. Either they want variety — the fifteenth sprint of the semester doesn't land like the first — or they've hit the harder limit: the race format only works for math that can be answered in a few seconds. The moment your class moves into adding fractions with unlike denominators, solving two-step equations, or reasoning about angle relationships, there's nothing left to sprint. The tool didn't get worse. The math outgrew the format.
This guide covers both situations: what 99math genuinely does best, where it stops, and alternatives grouped by the job you actually need done — more live-game variety, deeper fluency practice, or full-curriculum practice that can carry the concepts a sprint can't. One of the tools below is ours, and we'll flag that plainly when we get to it.
What 99math Does Brilliantly
Anything you add to your rotation should be measured against what makes 99math work in the first place:
- Zero prep: There's no kit to build and no question set to vet. You choose a skill, launch a round, and teach.
- Genuinely free: The live sprints that make 99math worth using aren't sitting behind a paywall, which is increasingly rare in this category.
- Real urgency: A live race gives the room a shared clock and a shared scoreboard. Students who would slow-walk a worksheet will fight for two more correct answers before the timer runs out.
- It targets something that matters: Fact fluency isn't busywork. A student who has to count up to find 7 × 8 is spending working memory on arithmetic that should be spent on the actual problem. Automatic recall is what makes multi-step math possible later.
Where 99math Stops
The sprint format has a hard boundary: it works when a problem takes three to eight seconds, and it breaks when a problem takes ninety. That isn't a flaw — it's the design. But it means 99math can't be your practice layer once the content requires sustained reasoning, which in middle school is most of it.
In practice, the boundary shows up in three ways:
- It's fluency, not concepts: 99math drills recall and quick computation. It has no way to carry fraction operations that need common denominators, multi-step equation solving, geometry reasoning, or anything where the thinking is the point rather than the speed.
- Speed pressure punishes your most careful students: In a race, the student who checks their work loses to the student who guesses fast. For facts, that tradeoff is acceptable. For problems that deserve a full minute of thought, it rehearses exactly the wrong habit.
- Nothing persists between rounds: A sprint is a class event. When it ends, there's no individual practice path for the student who missed half the questions, and no per-standard record you can act on next week.
So the question isn't whether to replace 99math. It's what to put next to it.
Job 1: More Live Games for Whole-Class Energy
If what you want is the live-round experience with different mechanics, these are 99math's closest cousins. All three are any-subject platforms, so the math quality depends entirely on the question set you choose or build.
1. Gimkit
Best for: Live review with a strategy layer · Price: Limited free tier; Pro about $10/month or about $60/year · Format: Live game modes with an in-game economy
Gimkit's twist is money: students earn in-game cash for correct answers and spend it on upgrades mid-game, which adds a strategy layer pure races don't have. It also softens the pace — students answer at their own rate instead of against one shared countdown, so it tolerates computation that takes more than a few seconds. It was created by a high school student, a fact classes reliably find delightful.
The catch for math teachers is the same as with every quiz platform: Gimkit delivers whatever questions you load into it, so a genuinely good math kit takes curation. And the free tier is limited enough that regular users usually end up paying for Pro. If you like the format but not the price, we've written a full roundup of Gimkit alternatives.
Pros: Strategy layer deepens engagement, gentler pacing than a pure race. Cons: Limited free tier, question quality is on you, still built for quick-answer questions.
2. Blooket
Best for: Middle school review variety · Price: Core is free; Plus tier is a few dollars a month · Format: Game-show modes, live and solo
Blooket is hugely popular in middle school for a reason: rotating game modes keep the format from going stale, the core product is free, and some modes can be assigned solo instead of played live. For a Friday review block, it's an easy win.
The tradeoff is question-set quality. Blooket runs on teacher-made and community sets covering every subject, and the math sets vary widely — some are excellent, many are recall-only. Like 99math, it rewards fast answers, so it works best on skills you want automatic rather than concepts you want reasoned through.
Pros: Free core, real mode variety, solo modes extend it beyond class time. Cons: Uneven set quality, speed-based, no standards-level reporting.
3. Kahoot
Best for: Occasional high-energy review · Price: Free basic tier for teachers; paid tiers for schools · Format: Live trivia quiz
Kahoot is the original live-quiz energy machine, and for vocabulary, mental math, and one-step recall it still delivers. The math caveat is structural: the countdown rewards answering fast, and multi-step math needs the opposite. A student who sets up a problem correctly but runs out of time learns that setting up problems is a losing strategy. Use Kahoot where speed and correctness point the same direction, and use something untimed for everything else.
Pros: Unmatched energy, familiar to every student, free tier covers basic classroom use. Cons: Time pressure is actively wrong for multi-step math, recall-oriented by design.
Job 2: Building Fluency, Not Just Racing It
Here's a distinction that gets lost: sprints reveal fluency more than they build it. The student who knows most of their facts gets faster and more confident in races. The student who knows less than half gets publicly reminded of that three times a week. What builds fluency for that second student is low-stakes, high-repetition practice measured against their own last score — not against the fastest kid in class.
For that job, dedicated practice tools beat live races. We've collected the strongest options in our guides to multiplication fact games and math fluency games, and the no-tech versions work just as well:
- Dice product war: Each player rolls two dice and multiplies; higher product takes all four dice-worth of points. Swap in ten-sided dice when six-sided gets too easy.
- Personal-best ladders: A three-minute mixed-fact set, self-scored, once or twice a week. The only opponent is last week's score, which keeps your weakest fact-students in the game emotionally.
- Close to 100: Deal four playing cards; students arrange them into two two-digit numbers whose sum lands as close to 100 as possible. Quiet, fast, and sneaks in place-value reasoning.
Job 3: Full-Curriculum Practice That Carries the Concepts
This is the job 99math was never built for: individual, standards-aligned practice across the full scope of a grade level — fractions, equations, geometry, proportional reasoning — with a data trail you can act on. Three tools worth knowing.
4. Infinilearn
Best for: Grades 5-9 · Price: Free (optional premium) · Format: Fantasy RPG
Full disclosure: we make Infinilearn, so read this entry knowing we have a horse in the race. We've tried to describe it the way we'd want a colleague to.
Infinilearn is a browser-based fantasy RPG for grades 5-9. Students battle monsters across 15 zones, take on quests and boss fights, and level up — and every attack, spell, and ability is powered by solving a real multiple-choice math problem matched to Common Core standards. Because it's persistent rather than live, it covers what sprints can't: the full grade 5-9 progression, from one-step equations in 6th grade through two-step equations in 7th to linear functions in 8th, plus fractions, geometry, and proportional reasoning along the way.
Two design details matter most for classrooms. First, the adaptive engine tracks each student's accuracy by topic, and weapon attacks pull problems from that student's weakest subjects — so in an ordinary battle, the kid who's shaky on fractions quietly gets more fraction problems without you building a differentiated assignment. Second, teacher accounts are free and include a built-in diagnostic to locate each student's level, plus assignment tools and tracking by topic, standard, and student.
The full game is free — every zone, quest, battle, and all grades 5-9 math, with no ads. An optional premium tier ($9.99/month or $59.99/year as of this writing) adds deeper dashboard insights and student cosmetics; it never gates math content or game progression. Honest caveats: we're newer and smaller than the incumbents, problems are multiple choice (no typed free response yet), it's grades 5-9 only, and it's browser-only — great on Chromebooks, not built for phones.
Pros: Full free coverage of grades 5-9 math, adaptive targeting of weak topics, free teacher dashboard and diagnostic, no ads. Cons: Newer platform, multiple-choice only, no native mobile app, nothing for K-4.
5. Prodigy Math
Best for: Grades 1-8, elementary-leaning · Price: Free to play; membership about $9.95/month · Format: RPG / pet collector
Prodigy is the established name in math RPGs: a big fantasy world covering grades 1-8, native mobile apps, and parent and teacher dashboards from a large, well-resourced company. The math questions themselves are free to answer.
The friction is the membership model. The rewards that drive the game — pets, gear, member-only areas — sit behind a membership of about $9.95/month, so free players practice inside a game whose best motivators they can't reach. And because the platform spans grades 1-8 with an elementary lean, older middle schoolers can find both the aesthetic and the content mix skewing young.
Pros: Established and polished, native apps, adaptive placement, teacher tools. Cons: Reward system gated by membership, elementary-leaning for grades 7-8, persistent upsell prompts.
6. Khan Academy
Best for: Instruction and mastery practice, all grades · Price: Completely free · Format: Video lessons + practice
Khan Academy isn't a game and doesn't pretend to be, but no list of 99math complements is honest without it. It's the best free instruction available: clear video lessons and mastery practice for every topic your class will touch, run by a nonprofit with no upsell.
Its limit is motivation. Khan works for students willing to sit down and study; students who need a reason to practice tend to stall out. A workable division of labor: Khan for instruction and worked examples, a game for the repetitions.
Pros: Free, comprehensive, excellent explanations. Cons: Not a game, requires self-motivation, feels like school.
A Realistic Weekly Rhythm
None of these tools competes with the others, because they do different jobs. Here's what a week can look like when each one stays in its lane:
- Monday, 5 minutes: 99math sprint as the warm-up, aimed at the fluency skill underneath this week's unit — multiplication facts before a fractions week, integer arithmetic before an equations week.
- Tuesday and Thursday, 15-20 minutes: Infinilearn practice blocks. Students play on Chromebooks while the adaptive engine handles differentiation; you circulate or pull a small group, then skim the class dashboard afterward to see who's stuck and on which standard.
- Wednesday: No games. Instruction, discussion, worked examples on the board. The games are a practice layer, and practice needs something to practice.
- Friday, 15 minutes: Gimkit or Blooket review round built from this week's content, plus anything the dashboard flagged midweek.
That's roughly an hour of game time across the week — enough to move fluency and give every student real practice reps, not enough to displace teaching.
The Bottom Line
Keep 99math. It's free, it's zero-prep, and five minutes of arithmetic racing on a Monday morning is a genuinely good use of five minutes. Just be clear-eyed about what it is: a fluency sprint, not a curriculum.
Fill the gaps by job, not by brand. If you want more live energy, Gimkit and Blooket are the closest cousins, with Kahoot for occasional recall rounds. If certain students need to build fluency rather than race it, use dedicated fact practice and personal-best formats. And for the biggest job — persistent, adaptive, standards-aligned practice across everything you actually teach — a full-curriculum tool like Infinilearn, Prodigy, or Khan Academy belongs in the rotation. The best version of your week probably includes a sprint, a practice block, and a review game, each doing the one thing it's best at.
