About this game

Make learning fun with Sumdog!

Sumdog delivers highly engaging personalized practice for math and spelling, both in-school and at home. Suitable for children aged 5-14, our adaptive learning games and online rewards motivate children to learn and encourages regular practice.

When children first use Sumdog, we run a short diagnostic test to provide a snapshot of their learning and areas for development. Our adaptive learning engine then uses the outcomes of the diagnostic to tailor questions to suit each child’s unique learning level. This provides a personalized learning experience to help children make progress.

- Over 30+ single and multiplayer games
- Thousands of multiple choice, standards-aligned questions
- Virtual coin rewards to motivate children to learn
- A 3D avatar, house and garden for children to personalize

“I never thought an online program could do so much in such short bursts of time.” D. Hendershot, West Elementary, Kansas, US.

In the Sumdog app, parents can purchase a family plan covering up to 3 children. Once you’ve done this, you’ll create logins for your child to use the app. This gives them access to Sumdog’s games, and thousands of math, spelling and grammar questions.

It has quite a few things that need to be fixed to make it easier and more playable by kids. I couldn't back out of some of the menus, I had to close the app and reopen it. It doesn't keep you logged in, you have to enter credentials each time you want to use the app. If these things get fixed I may resubscribe. I appreciate the app, but it needs work.

Hi, can you please contact us at and we will look into the issues you have raised. Could you tell us about the specific areas that you were unable to exit from? Every screen should be quit-able to get back to the main dashboard. If you log in out of school hours, it'll ask if your login should be remembered.

Nice app for learning, totally recommend it for this. And also, no adds!!! My only problem is that I can only play 3-4 games. If I try to play, for instance, Rollercoaster, the app would just shut. So it's basically crashing for most of the games, which makes everything a bit rubbish and almost unplayable. It's wierd, because this problem is only present on mobile devices. I have never experienced the problem described on a laptop or tablet.

Hi, we are currently investigating an issue on Samsung devices which means the app crashes in some games - we do not know why this happens as yet. Please use another device for now if you can?
