Graze

An orbit arcade game

Graze

One tap, two orbits, and a library of real courses: languages, sciences, medicine, logic and the great books.

Learn it in a lesson, recall it at a gate, keep it in an endless Feed that replaces scrolling. Everything returns on a spaced schedule until it sticks.

Graze in play: a brass orbit dial, a comet-like player, gold star shards and a rose block on the outer ring

How it plays

Fast hands, slow memory.

Every run mixes a twitch arcade loop with a few seconds of honest recall. The game pays far more for remembering than for dodging.

One

Graze the blocks

Tap to jump between orbits. Leave a block's lane at the last instant for a graze; chain them to build your multiplier and fill the Fever ring.

Recall at the gate

Time slows. You get a beat to remember, then two answers appear, one per orbit. Steer into the right one. A miss shows the answer and brings it back soon.

Build the run

Pick boons after each bonus rush, grab shields and magnets, and if you crash, one right answer brings you back.

Three ways to learn

A lesson, a run, a feed.

The same memory engine sits under all three, so a word you learn in a lesson comes back at a gate tomorrow and in the Feed next week.

Short lessons

Eight new sigils at a time, each with an example, a picture where it helps, and audio. Say it back and the microphone checks you. Then a quick check, and into your schedule.

The Feed

Swipe up through an endless stream of recall cards, new sigils, quick math, speaking and readings. Combos, golden cards and your streak keep it moving; every card is spaced review.

Pictures and maps

Name the highlighted part of the heart, a cell, the eye or a nephron. Find countries and states on the map, read the periodic table, and tell flags apart.

The science, honestly

What a game can actually do for a mind.

Graze is built on the parts of learning research that hold up, and leaves out the parts that don't.

Built in

Spaced retrieval

Pulling an answer out of memory strengthens it more than rereading, and spreading reviews out beats cramming. Gates follow a review clock from ten minutes to six months. Dunlosky et al., 2013

Built in

Vocabulary and word roots

Knowing words and how they're built is a main driver of reading comprehension. Graze ships with Greek and Latin roots, 600 advanced words, and whole beginner courses in ten languages.

Built in

Saying it aloud

Words you say aloud are remembered better than words you read silently, an effect known as the production effect (MacLeod and colleagues, 2010). Lessons and the Feed ask you to say words back, and check you with the microphone where the browser supports it.

Built in

Reading with comprehension

Nearly four hundred readings, from textbook-style explainers to exact passages from Plato, Augustine and Lincoln, each followed by questions you answer after the page closes. Reading pace only counts alongside understanding. Rayner et al., 2016

Built in

If-then habits

A daily ritual of twelve gates, anchored to a moment you choose. If-then plans have a medium-to-large effect on reaching goals across 94 studies.

Left out

Brain-training IQ claims

Practicing a cognitive game makes you better at that game, with little transfer to anything else. Graze makes no such claim. Simons et al., 2016

Left out

Speed reading

Flashing words faster trades away comprehension. Graze rewards reading that you understand.

What to expect: five to thirty new items a day, at the pace you choose, held on a schedule that keeps most of them for months. Graze makes no promise about intelligence; it helps you remember what you practice. To check it yourself, test a set of words before and after a month of daily play against a set you never saw in the game.

The Library

Thirty-seven courses, your order.

Pick what you want to learn and put it in order: your first course is your focus, and the rest mix in. Courses are written against free, reputable sources: OpenStax and LibreTexts textbooks, COERLL language courses from UT Austin, the Dickinson College Commentaries, Perseus, MedlinePlus, the Stanford Encyclopedia of Philosophy and Project Gutenberg. Each course lists its sources and was checked item by item, and most of the language and science courses had a second, independent review.

Updates

What's new.

The game checks for new versions on its own and shows these notes once after each update.

5.1.1 · Recall2026-10-10

  • Functional Groups: the amide-ion pKa now matches the range textbooks give (35 to 38).

5.1.0 · Recall2026-10-10

  • Functional Groups: a new course with 22 groups drawn as skeletal structures, the same groups inside aspirin, vanillin, acetaminophen and other real molecules, general formulas, naming suffixes and priority, and a pKa ladder.
  • Sapiens: The Big Ideas, a new course on the arguments of Yuval Noah Harari's book, with what critics dispute.
  • Recall it first: Feed cards hide their choices until you have tried to answer from memory. Functional groups also come back in reverse: you see a name and pick the structure.

5.0.1 · Checked2026-10-09

  • Independent reviews of 28 courses fixed several hundred items: distractors that were also correct, misquoted verses, wrong dates, accents and tone marks.
  • World Geography: every capital rechecked, map distractors are now real neighbors, flag distractors are real look-alikes, and Equatorial Guinea's new capital is in.
  • Reading questions no longer put the right answer in the same place.

5.0.0 · Library2026-10-09

  • The Library: 35 full courses, from Spanish, Latin, Greek and Japanese to anatomy, organic chemistry, calculus, logic, the Bible and the arguments for God, written from free, reputable sources such as OpenStax, LibreTexts, COERLL and Project Gutenberg.
  • Choose what you learn and in what order. Your first course is your focus; the rest mix in.
  • The Feed: an endless vertical stream of recall cards, new sigils, speaking, readings and quick math, built to replace scrolling. Press F.
  • Lessons: learn a unit's sigils with examples and audio, check yourself, then lock them in at your gates.
  • Pictures: name the highlighted part of the heart, a cell or the eye, find countries and states on the map, and recognize flags and elements.
  • Pronunciation: hear every word, and say it back. The microphone checks you in supported browsers.
  • Mental math: times tables, squares, powers and shortcuts, plus quick-math gates and adaptive speed drills.

4.1.0 · Orrery2026-10-09

  • A new look: an oxblood night sky, brass orbit rings with an engraved dial, gold star shards and a solar Fever.
  • Updates: Graze now checks for new versions and waits for you to tap Update, so a run is never interrupted.
