MathFun Help & Support

A little times-table practice each day. MathFun is free to download and play. Support: info@kanun.co.jp.

Start practising

Choose Practice on the home screen, create or select a profile, and answer at your own pace. Help opens the 1–9 multiplication chart. Profiles keep family members’ records separate.

Play together

Start Game offers computer battles, two players on one device, and online battles. Online: select a profile, then Quick Match, Invite a Friend, or Enter Code. Quick Match and invitations ask for Round Battle or Quick Battle. Enter Code uses the friend’s room mode. If no player joins Quick Match, a computer-controlled opponent may join after about 30 seconds. Invitations wait for your friend.

Online connection

Online features require your choice in Privacy & Support, internet access and Game Center. Check Settings → Game Center on the device. Family restrictions on multiplayer must be respected. Use the same current app version on both devices. Reopen a room if its code has expired. No separate MathFun username or password is required.

Back up or move devices

In Settings → profile management, use Backup to export a file or save to iCloud. On another device, use Restore and choose a backup. Automatic iCloud backups are available when signed in to iCloud with iCloud Drive enabled. A backup restore replaces the local profiles and records shown in its confirmation; export a backup first if you need the current records. Using the same Apple Account alone does not automatically merge local profiles.

Privacy, deletion and children

Open Settings → Privacy & Support for your online data choice and the privacy policy. Parents should decide whether children use online features and choose a nickname. Delete a profile to request removal of its uploaded nickname and scores. Backups must be deleted separately. There is no player chat, advertising or purchase requirement.
