Alien Percentages — quick percent math with whole-number answers
Alien Percentages is a mental math brain game that drills one everyday skill: taking a percentage of an amount in your head. Each round shows a question like 35% of $200, and you type the answer against the clock. Every question is generated so the percentage comes out to a whole number — the same shortcut logic you use on a real discount, without decimal debris. Difficulty adapts to your streaks, and questions never repeat from a fixed list. Alien Percentages is part of LEVO's Mental Math category and trains quantitative reasoning, processing speed, and estimation.
How to play
A percentage question sits on the card at the top — a percent, "of", and a dollar amount, like a price tag waiting for its discount. Beneath it, the answer row shows one underlined cell per digit of the answer. Work the percentage in your head — 10% twice and half of 10% gets you 25%, and the questions reward exactly that kind of shortcut — then type the result on the keypad; it checks automatically when the last cell fills. Correct answers flash green, score points, and bring the next question; a wrong answer flashes red, costs points, and freezes the timer on a review — "35% of 200 is" with your attempt crossed out above the correct value — until you dismiss it.
What it helps improve
- Quantitative reasoning — Percentages are ratios in disguise; converting "35% of 200" into a number strengthens how you understand and work with numerical concepts and data.
- Processing speed — The countdown turns each conversion into a speed rep, accelerating how quickly your brain handles and responds to information.
- Estimation — Benchmark thinking (10%, 25%, 50%) is estimation made procedural: the game is practice in making quick, accurate approximations you can trust at a shop shelf.
Levels & progression
50 timed levels with score goals; points are earned for correct answers and deducted for misses. The percentages and amounts adapt inside each round — friendly benchmarks while you find your feet, awkward ones once you're streaking — and settle back after a mistake. Because questions are generated rather than drawn from a bank, no session repeats, and your rank rises through Novice, Regular, Adept, and Master to Expert.
Questions & answers
What is Alien Percentages?
A mental math brain game from LEVO in which you compute a percentage of an amount — 35% of $200 — and type the answer before the round’s timer runs out. Every question is generated to have a whole-number answer.
Do I need to be good at math to play?
No. The questions are built around clean percentages of amounts they divide evenly, so the game teaches the benchmark shortcuts (10%, 25%, 50%) rather than assuming them — and eases back whenever you miss.
Why is it called Alien Percentages?
It is the space-flavored member of LEVO’s Mental Math category: the dollar amounts and percent-off framing play like discounts at an intergalactic market, and the name stuck.
