I Built My Daughter a Custom Learning Game. It Cost Nothing and Took 10 Minutes.

My daughter told me she didn't feel confident with her times tables. She had a test coming up, and she knew it. So we did what parents have done foreve; practice on paper, writing them out again and again. But those numbers just weren't sticking.

Her school suggested a game. I pulled it up, and immediately hit a login screen. Then another screen. Then an ad. Then a menu with about forty things on it, none of which were "just let my kid practice multiplications right now." We tried a couple of other apps. Same story - ads every five minutes, rabbit holes of other games to click into, and one school-recommended app that had a chat feature for young kids. I'm not even going to finish that sentence.

I just wanted something clean. No distractions. No data collection. No login. Just: here are the times tables, let's go.

That same day, I'd been using Claude (an AI tool) to help me plan and schedule my social media content for Tudrimi. At some point I asked it to make the planner interactive, so I could move posts around and track prep work visually. And it built me an HTML file that I could open in any browser, right on my phone or laptop.

So I did. I typed a simple prompt; genuinely, nothing fancy and within a few minutes I had a custom multiplication game. No login. No ads. Opens straight in a browser. Works on her tablet, my phone, the laptop at school, anywhere.

But here's where it got really good. I could personalise it. The standard apps don't teach strategy. they just throw sums at you and mark you right or wrong. So I asked the AI to add practical tips: ways to reach an answer from a starting point you already know.

For example: if your child gets stuck on 6×7, but they know 6×6, they can just add one more 6 to get to 42. Obvious when you read it as an adult. But for a kid, that connection, being able to work something out rather than just retrieve it from memory, is genuinely empowering. It's the difference between feeling stuck and feeling like a problem solver.

No app we tried did that. They just said wrong, try again.

Not just a multiplication game, a personalised learning tool, built in minutes, free, and designed exactly for her.

Once I realised this was possible, I didn't stop at one game. Here's what I've made for my daughter so far... each one below is a short demo video so you can see what they actually look like:

And that's just the start. I'm already planning a game that helps her revise her full year of learning, not just maths. The same approach works for phonics, spelling, science facts, geography, anything your kid is working on right now.

I'm going to be honest with you: I am not a prompt expert. I genuinely don't have time to be one. I just type what I need, as clearly as I can, and see what comes back. Sometimes I tweak it. Sometimes the first version is already good enough. That's it.

Here are my actual prompts, typos and all. Because if I cleaned them up into something polished, that would miss the whole point.

That one line started the whole thing. From there I kept the conversation going; tweaking, refining, asking for strategy tips to be added, telling it what I didn't want. Watch the demo below to see how the chat developed:

Want to go deeper on prompts? I've put together a download with my refined prompts for all three tools - ready to copy, paste, and make your own.

I described exactly what my daughter was saving for, how she earns money, and what I needed as a parent to manage it. The AI built it around that. It's not a generic piggy bank, it's her piggy bank, saving for her specific toy.

I told it the UK curriculum year, the age range, and the different ways I wanted kids to be tested. It figured out the word lists, the difficulty levels, all of it. I didn't have to research any of that myself.

Whatever idea you have, write it down like you'd explain it to a friend. Give it an age, a subject, a goal. Mention anything you don't want. That's genuinely all it takes.

The AI builds you an HTML file. You save it to your device - phone, tablet, laptop, anything. It opens in any browser. No internet connection needed once it's saved. No login. No subscription. No ads. It just works.

Want to update it or change something? Go back to the AI, describe what you want changed, get a new version, save it again. Each person saves their own copy, with their own progress stored on their own device.

I've made all three tools available to download below. Save them to your device - they work offline, no login, no subscription, no ads. Use them as they are, or take them into an AI tool and ask it to tweak them for your own kids.

And if you build something - I want to see it. Come find me on Instagram @tudrimi.
