A storybook world where children read, count, sing and discover. Every little step is a big adventure.
Plays right in your browser
Little lessons that build on each other, guided by a friendly voice and taken at your child's own pace.

From first letter sounds to blending words, then reading real sentences all by themselves.
Phonics and fluency
Adding, taking away, times and sharing, from first counts all the way up to the thousands.
All four operations
O'clock, half past and quarter to, with a big friendly clock to turn by hand.
Telling the time
Count nickels, dimes, quarters, loonies and toonies, then pay for a treat.
Money skills
Days of the week, months of the year, and a catchy tune for "Thirty days has September".
Days, months and seasons
Sing the tables from 1 to 12 with a bouncing beat that helps them stick.
Music and memory
Cozy picture stories where every word lights up as it is read.
Listening and reading
Trace letters and numbers with a finger, then try lovely joined-up cursive.
HandwritingFinish a round and a new friend might join the adventure. Each one has a special helper power, like counting out loud or sniffing out hidden treasure.
Each quest is a little journey across a hand-drawn map, with friendly puzzles along the way.
Every day they play, the tree sprouts a new leaf, flower or apple. Missed a day? That's okay. The tree simply waits and perks right up when they come back.
Day 1A tiny sprout
Day 3A surprise chest
Day 7Glimmer comes to visit
Day 14A garden crown
Grown-ups can set rest days, and a weekly shield keeps the streak safe on busy days.

We made Ollie's Adventure the way we'd want it for our own child: calm, kind and genuinely useful.
No banners, no pop-ups and no sneaky offers in front of your child.
No rushing timers and no scary sounds. A wrong answer simply means another try.
A weekly report shows what they learned, where they shine and what to practise next.
No accounts and no tracking. Progress is saved on your own device, and the microphone stays off unless you switch it on.
Settings, rest days and online play sit behind a quick grown-up check.
Skills unlock in a careful order, so children always feel ready for what comes next.
An example of what you'll see in the Parent Corner.
