What is Sumdog?

Questions are embedded into games, with different games for different learning styles – racing games, cooking games, flying games – there’s something for everyone. Sumdog is all about personalizing the experience for each child. The questions adapt to meet your child where they are while letting them play with friends, a robot or kids from across the world.

Makes learning fun!

Sumdog helps children to practise regularly. Combining fun games and achievements with curriculum-aligned questions, they won’t even realize they’re learning!

Rewards effort

For every correct answer, children are rewarded with coins to spend on their avatar or Sumdog house. And every time a child masters a new skill, their pet learns a new trick.

Adapts to your child

Sumdog gets to know your child’s ability with an initial diagnostic and takes them through the standards one skill at a time. You don’t need to set their level or adjust any settings – we’ve got it all covered.
