For Parents

Lio Dino is a fossil-dig and collecting game for children aged about three to six. It runs in the browser and works like an app on a tablet.

In short: A father made this game for his son and made it with love for every child. There is no subscription, no advertising and no data collection. In the Android app you play part of it for free; unlock it once (in the grown-ups’ area behind a parent lock) and everything is open. No account, no login, no timer, no losing.

Who is it for?

For children who cannot read yet. Everything that matters is read aloud: the dinosaur names, the facts, the hints. Controls are limited to swiping and tapping, and no menu is deeper than one level.

On the start page Lio peeks out of a circle – one tap on him and off you go. Next to him the child sees their newest dino friends. There is no time pressure and nothing to lose. A find is a find.

What your child learns here

44 dinosaurs by name. Every name is read aloud, so even words like “Parasaurolophus” stick over time.
Checked facts. Each find comes with four facts: size, era, diet, special features. A new one at every tap.
Question before answer. At the first find the game asks “What did it eat?” – and leaves the child a moment to guess.
Big, heavy, fast. Dinosaurs are compared with things a child knows: a hand, a banana, a child, a car, a house, a bicycle.
Counting to seven. Every dig site holds seven finds. “Three of seven found already!”
Six dig sites. Desert, ice, volcano, sea, jungle and quarry – and, in two sentences, why fossils lie there at all.

The games

After choosing a dino the game asks “What shall we play?”. Digging is the heart; the other games build on the child’s own finds.

A field of sand with dark rocks; brush, hammer and magnifier below — **Dig.** Brush away the sand, crack hard rocks with the hammer, uncover the skeleton. Then the find comes alive, roars and says its name.

A dinosaur cut into a few large puzzle pieces — **Puzzle.** The child’s own dinosaur in three to six large pieces; they snap into place when they roughly fit.

A dinosaur next to a conveyor belt with leaves, fish and meat — **Feed.** Leaf, fish or meat – and how many? “It wants three bites!”: the number stands big next to it, and every bite is counted out loud. The plant-eater spits out the meat – so it sticks who ate what.

A dinosaur as a colouring picture with paint pots below — **Paint.** Brush, stamps, paint bucket. The picture is saved and the dinosaur wears its new colours in the other games too.

Twelve face-down cards with dinosaur backs — **Dino Pairs.** Twelve cards, six pairs, different species every round.

A muddy Triceratops, half hosed clean, with buttons for water and sponge below — **Dino Wash.** First pick off the leaf, burr and snail, then hose and scrub, and finally blow-dry. Along the way the child learns body parts (“Wash the tummy!”) and the species’ feature.

A Stegosaurus on a meadow next to a big and a small nest, with eggs floating on a river below — **Egg Sort.** The eggs are floating in the river; the child drags each one into the right nest – sometimes by size, sometimes by colour. It practises comparing, naming colours, counting and switching a rule.

A wooden board with earthy tiles and dinos in block shapes – a Brachiosaurus as a tall L, a T-Rex as a square – with a meadow of seven little dinos on the left — **Dino Stack.** Every dino has a shape that fits its body: the long neck makes a tall L, the wings a long bar. The child places them on the board; when a row is full they run off and are counted, until ten sit on the meadow. It practises fitting shapes, thinking ahead and counting.

Lio holds his magnifying glass in a snowy landscape; footprints lead to a snow mound with a tail tip poking out; below, three big answer cards with dinos — **Egg Hike.** Lio walks by himself through one of five worlds – meadow, ice, cave, underwater, volcano – pulling a chain of eggs behind him. At three stations he asks something: How many icicles? Who made these footprints? Whose shadow is that? Each answer adds an egg, and at the end everyone counts the eggs into the nest. On the way the child helps with a swipe to jump, slide and climb – if nothing happens, Lio manages on his own after a few seconds. It practises looking closely, working out the whole from a part, counting and comparing.

A big letter A on a board, the left leg already filled, the right one half; Lio walks along the stroke, next to it an Ankylosaurus with its name — **Lio's Dino ABC.** A big letter stands on the board, next to it the dino whose name starts with it. The child traces it with a finger – start at the green dot, follow the arrow, stroke by stroke as in handwriting lessons; it fills up behind the finger and Lio walks along. When it is full, the dino hops onto it and the narrator says “A is for Ankylosaurus!”. Capital letters and the first sound only, no reading. It practises the writing movement, recognising letters and guiding the finger carefully; the ABC book collects the letters done.

Lio’s Friend Book

Every dino the child finishes a round with – dug up, puzzled, fed, painted, washed, eggs sorted or photographed – becomes a dino friend. Every friend gets a page in Lio’s Friend Book – where it lives, what it likes to eat, how big it was, when it lived, the photo from the safari and which games the child has already played with it. The friends count towards four levels: with 5 friends the child is a Dino Buddy, with 15 a Dino Pro, with 25 a Dino Star and with all 44 a Paleontologist. At every level a stamp flies into the book, the child’s own dino gets a hat, a badge and a necklace, and from level two the brush turns golden. No time pressure, no luck, nothing is lost: every level can be reached, at any pace and with any favourite game.

Each level comes with a printable certificate. You will find it in the grown-ups’ area (“For parents” at the top left of the start page, then the code lock) under “Friend book and certificate”: enter the child’s name, save the certificate as a picture or print it right away. The name stays on your device only; without it, the certificate has a line to write it in by hand.

How to put Lio Dino on a tablet

Lio Dino is a web app. Once “added to the home screen” it starts like an app without a browser bar and, after the first visit, works without internet.

iPad and iPhone (Safari): open lio-dino.com, tap the share icon (the square with the arrow pointing up), then “Add to Home Screen”. Note: Safari deletes saved progress when a page has not been opened for seven days. Started from the home screen, everything is kept.
Android (Chrome): open lio-dino.com, tap the three-dot menu, then “Install app” or “Add to Home screen”.
Windows and Mac (Edge or Chrome): open lio-dino.com and click the “Install app” icon in the address bar.

Lio Dino also exists as a single file that can be passed on by e-mail or USB stick and runs entirely offline – handy for kindergartens and tablets without Wi-Fi. Drop us a line and we will send it.

Privacy in two sentences

Lio Dino collects nothing. There are no accounts, no cookies, no advertising, no analytics and no third-party content; progress stays in the browser of the device and is never transmitted anywhere. The same goes for the name you can enter for the certificate: it never leaves the device.

The full privacy policy is on its own page (in German, as required by Austrian law).

Found a bug? Have a wish?

Send an e-mail to hello@prompt-it.me. The game offers the same route: “For parents” at the top left of the start page opens the grown-ups’ area after a small code lock – with the child’s progress, play time, the explorer-pass certificates and a button “Report a bug or a wish”.

Why are there no ads?

This game is dedicated to Lio, who loves dinosaurs more than anything. Try it free, unlock it once, and everything is included: no subscription, no ads, no further purchases, no data. Children never see the purchase – it sits in the grown-ups’ area behind a parent lock. So parents can hand over the tablet without worry.
