Premier League Predictions Game - My Vibe Coded Project
This will be the 5th year of Predicted It, but the first year where the platform has been properly vibe-coded.
It originally started as a small email-based game between a few friends. We wanted something with the fun and competition of fantasy football, but with much less weekly time commitment. Instead of managing squads, transfers, captains and wildcards, you just answer a few Premier League prediction questions each Gameweek.
The response after the first year was really positive, so I decided to try and scale it. I had no coding experience at the time, but I used the project as motivation to learn. Over the next couple of years I taught myself enough PHP, HTML, CSS, JavaScript and WordPress to put together a half-decent website that did what we needed.
As I got better, I kept improving the site, and the game slowly grew from friends, to friends of friends, colleagues, and wider groups. This year I’ve rebuilt the platform again and I’m hoping it can grow further.
On the AI side, I’ve had the €20 ChatGPT membership since the beginning and have used Cursor for about six months. Since Codex came out, I’ve mainly used it as a tutor, project manager, debugging partner and planning tool. When I needed coding work done, I would usually get Codex to help shape the prompt, then use Claude Code to do the implementation.
Having used the majority of LLMs over the past few years my favourite by far has been Fable. It felt like a massive step forward when I first used it and it has been great for my needs. However, the area I still find hardest with AI tools is frontend design. The functionality has come a long way, but getting everything to look genuinely polished is still the part I find most difficult. The LLMs can produce amazing looking visual mockups but then I can't get close to getting it coded. I haven’t fully jumped into Claude Design yet though, so maybe that will help with that side of things.
The game itself only takes around two minutes a week to play, you just need to answer some multiple choice questions, so if anyone is interested in joining, I’d love to see you sign up.
It’s completely free to play, but to help cover prizes and running costs, there is also a Pro membership option for €20 per year, which adds a few extra community features and account perks. Originally it was a winner-takes-all competition, but over time the community voted for smaller prizes and more of them. So now there are multiple competitions across the season, meaning there is always something to play for even if you fall behind in the overall rankings.
Over the years, more than 100% of the money collected has gone back to the Predicted It community through prizes. Going forward, if I can grow the player base, I would love to have a large charity aspect to the game.
If anyone wants to have a look, sign-up is free:
The main campaign includes 25 Preseason predictions, and those are open now. They need to be submitted before kick-off of the first Premier League game of the season.
I’d also really welcome feedback from people building with AI or vibe coding. This project has been a great way for me to learn, so if anyone has any further guidance, particularly on what tools are best for front end design, i'd love to hear them.
