Dinosaur Picker

Watch the nest

Fill the nest

Tap dinosaurs to add or remove their eggs from the clutch (up to 12).

Somewhere in this nest, a dinosaur is waiting to hatch. Your dinosaurs rest inside speckled surprise eggs, and when you press Hatch One a warm glow hops from egg to egg, settles on one — and it cracks open. Whatever climbs out is your dinosaur. Pick which eggs go in the clutch, add your own, and let the nest decide.

Crack open a surprise

Hatch a surprise egg to pick a random dinosaur

Ask a dino-mad kid to pick just one favourite dinosaur and you'll be there all day. The Dinosaur Picker settles it the way nature would: with eggs. Every dinosaur in your clutch rests inside a speckled surprise egg, and when you press Hatch One a warm glow hops across the nest, settles on an egg — and it cracks open. Whatever rises out of the shell is the pick. The winner is chosen fairly before the glow starts moving, so the wobble and the crack are pure suspense over a genuinely random result.

Fill the nest

The nest only hatches eggs you put in it. Tap dinosaurs to add or remove their eggs, and type in any that are missing — obscure favourites, correctly-pronounced tongue-twisters, or an entirely invented species. Keep the clutch to the dinosaurs you'd be happy to get, and whatever hatches is a good result.

Meet the clutch

If an egg hatches something you don't know yet, here's who might be inside:

DinosaurWhen it livedClaim to fame
T-RexLate CretaceousThe most famous predator ever — bite force of a school bus landing on you
VelociraptorLate CretaceousTurkey-sized, feathered, and frighteningly clever
TriceratopsLate CretaceousThree horns and a bony neck frill — T-Rex's classic rival
StegosaurusLate JurassicBack plates for show, tail spikes for business
BrachiosaurusLate JurassicFront legs longer than back — built like a giraffe the size of a house
SpinosaurusCretaceousBigger than T-Rex, swam rivers, wore a sail
AnkylosaurusLate CretaceousArmoured like a tank with a sledgehammer tail
MosasaurusLate CretaceousNot a dinosaur at all — a giant marine reptile that ruled the seas

When to hatch an egg

  • The endless favourite debate. When "which dinosaur is best" has gone on for twenty minutes, let the egg answer.
  • School projects. Assign each student a dinosaur to research — the nest hands them out with zero arguments.
  • Story time. Hatch an egg, then read about (or make up a story starring) whoever climbs out.
  • Drawing prompts. One hatch equals one drawing challenge — Parasaurolophus is worth bonus points.
  • Toy-shop tiebreakers. One pocket-money dinosaur, five candidates? The egg decides, tears avoided.

A fair hatch every time

No egg sits luckier than another. The winner is chosen with your browser's cryptographic random generator — the same kind of randomness used for security — before the glow moves, and the eggs shuffle into fresh nest positions before every hatch. The wobble, the crack and the pop of the shell are showmanship; the pick is genuinely unbiased.

Frequently asked questions

The hatching egg is picked first with your browser’s cryptographic random generator — before the glow even moves — then the glow is choreographed to settle on it. Every egg has exactly the same chance; the wobbling and cracking are just the fun part.

Yes. The eggs shuffle into new nest positions before every hatch, and the winning egg is chosen uniformly at random, so no dinosaur ever owns a lucky spot in the nest.

Yes. Type any dinosaur into the “Add your own dinosaur” box — a Pachycephalosaurus, a made-up backyard-o-saurus, anything — and it gets its own egg in the nest.

Up to twelve at a time, each resting in its own little nest. Toggle dinosaurs on and off in the grid to build the clutch you want.

Because every dinosaur started as an egg! Watching an egg wobble, crack and hatch is a much more exciting reveal for kids than a flat wheel — and the result is just as random.

Completely free, with no signup. It runs entirely in your browser.

Very. Teachers use it to assign dinosaurs for projects, pick which dinosaur to read about next, or just as a five-minute reward — kids take turns pressing Hatch One.

Yes. The nest scales to your screen and the egg chooser opens in a side panel, so it works on phones, tablets and desktops.
