Ozy's World
The finest legacy of all: teaching children about money. Ozy's World is a games academy designed for ages 6-13, guided by Ozy the firefly — the same Zero-Knowledge standard, the same elegance, nothing that ever leaves the device.
Sixty games, three ages
The academy brings together 60 games across 12 modules and 3 tiers — ages 6-8, 8-10, 10-13. Children learn the essentials through play: telling need from want, recognizing coins, giving change, waiting in order to save, discovering the world's currencies… all the way to the first notions of disposable income and cryptography.
Gems, badges, a diploma
Each game won lights up a gem; each completed module earns a badge; each finished tier awards a diploma. The progress, like yours, stays on the child's device — no score is ever sent anywhere.
Ozy's World already exists in six languages and can be chosen with a tap, with its own colourful themes designed for children.
Free, no ads, no account
- 100% free with no advertising whatsoever: nothing to buy, nothing to unlock.
- No account, no sign-up: a child leaves no trace, no personal data.
- A bridge to the grown-ups: the same ideas — need/want, saving, disposable income — as in your vault, in playful form.

A game with a child
Open Ozy's World and start a first game with a child around you — « Need or Want? » is a great beginning. Watch how an abstract idea becomes crystal clear the moment it's played. This is how a whole family learns to talk about money calmly.
