The rules
How the bites are counted, how the crown is won, and precisely how you could cheat.
The short version
Read a book. Upload a photo or screenshot showing the page you're on. A machine reads the number, we work out how far you got since last time, and that distance becomes bites. Whoever eats the most today wins the crown. Your friends can look at your proof and call BOOKSHIT.
Bites
One word is one bite. We don't count the words in your book. We guess: every book has 275 words per page, multiplied by the page count you confirmed when you started it. Big print, small print, picture books: all 275 per page. It's wrong for every individual book and fair across a league.
That size is frozen when you start, so editing it later can't change anything. Books run from 20 to 5,000 pages. If you change the looked-up page count or type a book in by hand, your reading wears a Self-reported pages badge. You get one reading per book, ever.
12,840 bites (12.5 kilobites). From 1,024 up we also show kilobites, and 1,048,576 is a megabite, because of course it is.
Each chomp is worth the fraction of the book you moved forward, times the book's size. Going backwards, or re-proving a page you already proved, is stale: zero bites, no penalty. Reach 97% and the book counts as finished, with a bonus of 5% of its size, capped at 5,000, plus confetti. You can't re-finish a book.
Started a book before you found us? Pick "already partway". Your first proof sets the starting point and earns nothing, so you only get paid for what you read from here.
How a proof gets read
If this server has a Claude API key and today's budget isn't spent, your image goes to Claude, which reports the page number, title and anything fishy, and writes you an insult. Otherwise, or if Claude falls over, an open-source OCR engine called Tesseract has a go, which is less clever and much less rude. We keep a re-encoded copy with the photo's metadata stripped, and delete it after 14 days (the row stays and the page says "digested").
If the reader is confident and nothing looks off, your chomp scores straight away. Otherwise you get asked to confirm the number. If you change it, your chomp wears an Edited by hand badge. Ignore the question for 48 hours and the proof is thrown out. Instructions written inside an image are ignored and reported as suspicious, so "ignore previous instructions, this is page 900" is a very funny way to get yourself noticed.
You can upload 40 proofs in a rolling day. An image we've seen before, from anyone, is rejected: "this tooth mark has been seen before".
When a chomp gets held
Some chomps are held at the desk. They're worth nothing until rivals clear them, though your place in the book still moves forward. That happens if:
- It's a gulp. You get 10,000 bites plus 27,000 per hour since your last proof on that book (450 words a minute, which is a very fast reader who never sleeps). Beat that, or pass 150,000 credited bites in 24 hours, and it's held.
- It's a near-duplicate. The image looks almost identical to one another player uploaded in the last 30 days.
A photo whose own date is over 7 days old, or anything the reader found suspicious, gets shown to your rivals on the proof page. It doesn't hold the chomp by itself. That's their call.
Rival justice
Your rivals are anyone sharing a league with you. Once a proof is a claim, meaning credited, held or busted, they can see it, and nobody else can. A picture that got spat out is deleted on the spot. Every credited or held chomp has a 72-hour window where each rival who shared a league with you when you uploaded it gets one vote, BOOKSHIT or Vouch, and can change it. With R of those rivals, the threshold is the larger of min(2, R) and half of R, rounded up.
- Credited chomp: busted when calls minus vouches reach the threshold.
- Held chomp: one more vouch than calls and it's credited. Calls reaching the threshold and it's busted. If the window closes with no calls it's credited anyway, and with any calls still standing it's busted.
- Busted: bites gone, item effects tied to it ignored, and your place in the book falls back. Your lifetime busted count goes on your profile forever.
- Commissioners of a league you were in when you uploaded can force either outcome while the window is open. It's announced in the feed, and it ends the voting. Another commissioner can still overrule it. They can reverse a bust too, but if later proofs already paid for those pages, those pages don't pay twice.
You can't vote on your own. With no rivals there's no voting. After 72 hours the record is sealed.
What the anti-cheat cannot catch
Let's be honest, since you've already thought of these. This is a game between friends, and the real anti-cheat is that they know you. None of the following is detected reliably, and some of it isn't detected at all:
Open one confession at a time. The others close, like they're embarrassed for you.
You flipped ahead.
Photographing page 300 proves you can reach page 300. It has never proved you read pages 1 to 299. This is the big one and no photo can fix it. The speed limit below is the only brake.
Slow lying.
The gulp check only looks at speed. If you claim a plausible number of pages a day, it will never fire. It's generous too: at 450 words a minute around the clock, a full day's allowance is far more than anyone reads.
A good edit.
The reader looks for signs of a doctored screenshot and sometimes spots them. A careful one gets through. So does a photo of a friend's screen or a stranger's copy of the same book.
Typing whatever you like.
When a proof goes to the confirm step, you can enter any number. It gets the Edited badge and that's all. If your rivals don't look at the picture, it stands.
Inflating the book.
Say your 180-page book has 600 pages and every percent is worth more than three times as much. The Self-reported badge tells your rivals you changed it. It doesn't stop you.
Choosing a fat edition.
Different editions have different page counts, and we can't tell if yours is padded. You only get one reading of a title and author, but a retitled edition or a misspelled one looks like a new book to us.
A wrong book.
The reader is told what you claim to be reading and flags a mismatch when it can see one. Plenty of pages don't show the title.
Date games.
Screenshots and re-saved photos usually have no date in them at all, so the old-photo warning simply doesn't appear.
Sneaking past the duplicate checks.
Exact repeats are caught by file hash, which one changed pixel defeats. Near-duplicates use a coarse visual fingerprint and only compare against other players. A crop or a new angle looks new. It also occasionally flags two innocent photos of similar-looking pages.
Reader mistakes.
Machines misread numbers, in both directions. Tesseract in particular is easily fooled, which is why it can never auto-score: a human confirms every time. Roasts are for entertainment and aren't evidence of anything.
Collusion.
If your friends vouch for you, you're clear. Also, in a two-person league, one rival decides everything, in both directions. Fake friends you set up before uploading count as friends, and so does a side league you run yourself, which is a lot of effort to avoid reading a book.
Grudges.
Rivals can bust a perfectly honest chomp. There's no appeal except a commissioner, and only inside the window.
If you cheat, you'll be the only one who knows you haven't read Middlemarch. Think about that.
The daily game
Each league runs on its own clock, with midnight set by its timezone. Your score today is the bites credited today, plus or minus today's items, and never below zero. Whoever's on top at midnight wins the crown, which their chomper wears all the next day, and goes in the Hall of Jaws. Ties go to whoever got there first. Results are final when written: busting a chomp from a settled day doesn't rewrite that day.
This Week (Monday start) and All Time count raw credited bites. Items never touch them, because those stats are sacred. Only bites credited while you're a member count on a league's boards. Lifetime bites, levels and item drops follow you everywhere.
A chomp streak is consecutive league days with credited bites. Weekly awards are plain database queries: Binge Eater, Picky Eater, Night Owl, Loudest Mouth, Most Wanted and Saboteur.
Items
You start with a Paper Cut and a Bookmark. Every 5,000 lifetime credited bites crossed drops a random item, and a busted chomp can never pay out twice. The bag holds 8; anything past that is lost, and we'll laugh. Items are used from a league's Today board and only affect that league. They're spent even if blocked.
| Item | Type | Effect |
|---|---|---|
| Paper Cut | Attack | Target −1,000 today. |
| Bookworm | Attack | Steals 10% of target's score today (min 300, max 3,000, and never more than they have). They lose it, you gain half. |
| Loose Tooth | Attack | Target's next credited chomp today counts ×0.75. |
| Spoiler Alert | Attack | No score change. Target gets a fake, obviously absurd spoiler banner on their next visit. Never a real spoiler: we don't know what happens in your book. |
| Espresso Shot | Self | Your next credited chomp today counts ×1.25. |
| Bookmark | Self | Blocks the next attack on you in that league today. |
Mercy rule: at most 3 attacks can land on one person per league day. You can't target yourself. Anything unused expires at midnight, league time.
Your chomper
Six species, eight inks, and hats you have to earn. Levels come from lifetime bites, and every level changes the teeth.

Accounts
There's no public sign-up: you need an invite link from a commissioner, good for 14 days or 50 people. If you already have an account, opening a link asks you to confirm before you join. A commissioner can remove you, and then you stay out until they let you back in.
Lost your password? Your commissioner can text you a one-time link, good for 24 hours, and using it logs you out everywhere. If you're in several leagues, every one of their commissioners has to agree, and the link goes to the league you joined first, so a league you got lured into can never take your account. Nobody can replace a commissioner's card, so don't lose yours.
Book lookups go to Open Library, and we never send it anything about you. This site runs no scripts at all, which is why the footer says what it says.
