About
Mathamphetamines is a free, browser-based collection of math games designed to be just addictive enough that you forget you're practicing arithmetic.
The "Get High on Math" concept
The name is a play on words. The premise: a clean math habit can hit like a stimulant — fast pulse, narrow focus, time slipping by. Same neurochemistry as any good puzzle flow state, none of the comedown. We lean into "underground/dealer/alley" theming because it's funny and it works as a hook, not because we're glamorizing anything. No real drugs are involved, condoned, or referenced beyond the joke.
The actual high here is doing math fast and well. Streak ×8 in Quick Hit hits like finishing a hard crossword. Crushing a x6 combo in Number Crusher hits like clearing a Tetris quad. Beating your high score hits like beating your own personal record at anything. That's the loop we're amplifying.
What's the goal?
Mental math is a use-it-or-lose-it skill. Most adults stopped practicing it the day their phone got a calculator. Mathamphetamines is meant to be a low-friction, high-fun way to keep that muscle warm — three to five minutes a day, while you wait for the bus or your coffee.
Under the hood, the games hit the four basic operations (add, subtract, multiply, divide), and the difficulty quietly scales with your skill. As you progress through the six city stages — The Block, The Back Alley, The Gas Station, The Coney Island, The Pawn Shop, The Underground Casino — the problems get harder, the targets get bigger, and the rewards get fatter.
How it works
Pick a game. Solve math problems against the clock. Earn HITS. Spend HITS in the alley on gear for your avatar (chains, hats, hoodies, even a tuxedo) and furniture for your home base (rugs, paintings, a golden throne if you grind enough). Complete jobs the dealer hands out to advance through stages and unlock new locations.
Everything is free to play. We don't sell HITS, and the in-game economy has no real-money component. Currency lives in your browser and goes away if you clear your data.
The games
- Quick Hit — 60 seconds of rapid-fire multiple-choice arithmetic with a streak multiplier. Pure speed.
- Number Crusher — tap tiles on a 6×6 grid that sum to a target. Combo system rewards back-to-back clears.
- Math Runner — 3-lane endless runner. Math gates approach with answers in each lane. Pick the right lane or eat pavement.
- Equation Builder — tap digits and operators to construct an expression that equals the target. The puzzle one.
The kid-friendly version
We get that the name and theming aren't a fit for schools or younger kids. There's a sister site, Math Quest, which is the same engine and games rebranded with adventurer/wizard theming and age-appropriate copy. Same math, different vibe.
Who made this?
Built and run by one person. Hosted statically (Netlify). No tracking pixels, no newsletter pop-ups, no follow-me-around-the-internet ad strategy. If we ever add advertising it's to keep the lights on, not to harvest you.
What's next
Roadmap items in flight or planned: real cross-device accounts (backend), real global leaderboards, more game modes, expanded questlines beyond the six stages, optional cosmetic IAP for support, and a school/classroom version of Math Quest. If you want something specific, hit the contact page.
