Features & use cases

Learn through a game world

99math presents math practice in a colourful game world rather than a plain worksheet. The captured home area includes a character guide, a personal avatar, pets, friends, rewards, a shop, skills, and decoration controls that make progress feel connected to an evolving space.

Use the world view to return to ongoing activities and see the next available option. Its playful setting can help make regular practice feel more like a short game session than a separate school task.

Join with an account or class code

The sign-in screen supports Google and email-or-username access, with a free sign-up path for new players. Once signed in, the main screen includes an Enter Code control for joining an activity or world through a supplied code.

This setup is useful when a learner is participating in a teacher-led, classroom, or group activity. Keep account details and any join code available before starting so progress can be associated with the intended player.

Collect rewards and build progress

The interface provides routes to rewards, pets, friends, skills, and a shop alongside the central world area. These elements give learners places to review what they have unlocked and personalise their experience as they continue with the app.

Parents and educators can use the visible progression layer as a conversation point around regular maths practice. The exact activities available can depend on the player account, assigned code, and current in-app progress.
