"There's a trend at the moment of solving online games with programming, let's do one from the UK called Passport Application, which is developed by "His Majesty's Passport Office" or HMPO. It's a cultural phenomenon in the UK: despite being quite expensive (about £100 just to start) for the standard online version (a masterpiece of minimalist design, entirely text-based), most British play the game, and do so every 10 years or so." https://jameshaydon.github.io/passport/
