Wow, what a cool idea! Fits in the wallet, I assume?

It does, yes! I realised after playing that I couldn’t remember the last time I won, and wanted to keep track!

There is also an official scoresheet app which really does the job

Yes, I wasn’t aware until after I made this!

There's an official one if you're interested. It's free, although you need to take it through the checkout - https://www.pnparcade.com/products/sprawlopolis-scoresheet

Thanks - I did not know this!

BG Stats now has score cards for many games, including Sprawlopolis that get saved with each play.
