Everything you need to know before you begin.
What's the vision behind GroGroJello?
We dream of a world where every child can enjoy learning maths, no matter where they live or what their family can afford. Through play and the joy of raising a Jello, we're making maths more approachable and working towards a future where AI-powered maths learning is accessible to everyone.
Who is GroGroJello for?
It's a playful way for children to get interested in maths and practise basic arithmetic. Start with small challenges that match what your child is learning now. Parents can join in, and adults rediscovering maths can have fun, too.
What's a maths adventure with Jello like?
Take on maths missions and use your rewards to raise a Jello of your own. Feed them tasty treats, clean up their poo and give them baths as you care for them each day. Maths practice becomes part of the fun as you watch your Jello grow and set off on your next adventure.
What maths topics can my child practise?
Counting, arithmetic and fractions are just some of the primary maths topics children can practise. Games also bring everyday concepts such as shapes, measurement, time, money and graphs to life.
Does GroGroJello support what my child learns at school?

What devices can we use?
You can play in a web browser on a phone, tablet or computer. On supported devices, you can also add GroGroJello to your home screen or use the Android app.

Can my child play on their own?
Simple tap-and-drag controls let children take on missions and care for their Jello. Explore together at first, then let your child play on their own as they get comfortable. When a new concept or tricky problem comes up, work through it together.
