Kickstart your career as a web engineer and ship predictor.html before kickoff: a single-file HTML+CSS+JS prediction game you write line by line in our WebGame Lab, then deploy to a live https URL. Real 2026 fixtures, your own 5/2/0 scoring engine, a bot whose brain you compute from real historical results, a localStorage leaderboard. Graded on scoring, real-data modelling, completeness, and deployment. Not affiliated with FIFA, SAP, the DFB, or GOAL.

A real case study built on ProoV, completed step by step and graded by ProoV.
Meet Leo, your guide. Tell him where you are starting from, meet the code workshop, and make the game title your own.
Show the real 2026 World Cup matches on the page, each with two boxes where a player types their predicted score.
Write the rule that hands out points: 5 for an exact score, 2 for the right winner, 0 for a wrong guess.
Compute attack strength from real past results, then build a simple computer player to beat.
Keep everyone's points and rank them, you vs the computer vs friends, so it survives a page reload.
Put your finished game on the internet for free and submit the live link.
You write the HTML, CSS, and JavaScript for one file, predictor.html, a part at a time, and watch it come alive in a live preview as you type.
You compute every team's attack strength from a public-domain results sample and use it to power a bot that predicts scorelines. The same shape of work data-driven product teams pay for.
You put your finished game online for free and walk away with a live web address you can put on your CV and send to a recruiter or a friend.
