Meet the Lost Islands

Is it really free?

Yes. The browser game is free to play, with no account, adverts or in-game purchases. Skyla and Nova are too young to make pocket money yet.

What will children practise?

The Lost Islands combines UK Year 3 spelling, typing and maths with six islands to explore. There are hints, adjustable learning settings and a grown-ups’ area inside the game.

Will our progress be saved?

Progress stays in this browser on this device. Come back here to pick up where you left off. Clearing website data removes saves, and private browsing may not keep them. Progress doesn’t sync to other devices or the app.

How do we play?

Use a keyboard and mouse, or the game’s on-screen controls on a touchscreen. Turn a phone or tablet sideways for the game. Sound starts after you interact, and can be adjusted in Settings.

Is there an app?

The iPhone and iPad app is coming soon. Skyla and Nova are busy play testing it.
