Chat with friends. Learn times tables too.

They actually want to play

Playing a multiplayer game with a real friend is exciting. Playing with a random stranger is not. When your child is playing with someone they know, they want to come back, and every game is a times tables session.

Chat makes it social

Children want to chat. In most apps, chat is either missing or unmoderated. Here, they can talk to their friend during the game: tease, celebrate, plan their next move. It is the social connection that keeps them engaged in the maths.

Friendly rivalry drives effort

Beating a random stranger means nothing. Beating your sibling or best friend means everything. That friendly rivalry makes children try harder, and trying harder means more times tables practice.

They know each other's level

Friends and siblings know each other's abilities. A younger child is not crushed by an older one. They adjust, encourage, and play at a level that works. No random matching that is too hard or too easy.

They keep each other coming back

"Play me!" is the most powerful motivator there is. When a friend or sibling sends a challenge, your child wants to accept. That social pull keeps them practising, without you having to nag.

No strangers, ever

There is no matchmaking with random people. Your child only plays with people you have approved: siblings, schoolmates, or friends added via a private code. You are in control of who is in the squad.

Chat is locked until they play

Your child cannot just open the app to message friends. They have to answer a maths question first, so every chat is tied to real practice.

You see every message

Full chat logs in your dashboard. No message is hidden, no conversation is deleted.

Wellbeing reports

Our engine analyses every message for kindness, confidence, bullying and anxiety, and gives you a warm summary.

Siblings: automatic

Add more than one child to your family account and they are instantly in each other's squad. No setup needed.

School friends: by code

Enter a school code and classmates whose parents have enabled discovery appear. Both parents must opt in.

Other friends: by player code

Your child needs their friend's full name and private XTC player code. Both children must accept, so no one-sided adding.

Every message your child sends and receives is saved. You can read the full conversation history in your parent dashboard. No message is hidden.

See which friends your child chats with the most, how many messages they have exchanged, and how active each friendship is.

One toggle in your parent dashboard turns chat off completely for your child. No messages sent, no messages received, just the game.

Our engine analyses every message for kindness, confidence, bullying and anxiety, and gives you a warm, school-report-style summary.

of the time, older siblings naturally teach younger ones during informal play at home, building maths understanding for both.

Younger siblings of high-achieving older children score higher in maths and reading by middle school: the "sibling spillover" effect.

Yale University, American Journal of Sociology (2023)

the learning: the older child deepens their understanding by teaching, while the younger child picks up maths earlier than they would alone.

Concordia University, Infant and Child Development (2016)

Research from Concordia University found that "by the time children enter school, they have already become familiar with certain mathematical concepts because they spend so much time playing together at home." Older siblings naturally teach younger ones, and the younger ones pick up maths years ahead of where they would be on their own.

Instead of siblings arguing over the TV or retreating to separate screens, they can challenge each other to a multiplayer times tables game. It is something they can do together, and it is maths practice disguised as a sibling rivalry.

Bingo supports up to 30 players, so the whole family can join. Mum, Dad, grandparents, cousins, siblings: everyone plays at the same time, each on their own board. It is a family game night that happens to be times tables practice.

Every child earns coins as they play, and both siblings can redeem coins for real-world family rewards you set: "football with Dad", "movie night of your choice", "hot chocolate together", "choose dinner tonight". So both children are motivated to play, and both can earn quality family time. See how rewards work →
