The Hardest Part Wasn't Building the Website

When I started Lotto Pattern Check, I thought the biggest challenge would be building the application.

I was wrong.

The hardest part has been collecting and organizing historical lottery data.

Every lottery has its own format, rules, draw schedules, and archives. Some make historical data easy to access. Others don't.

What I expected to be a simple number picker turned into a data collection and normalization project.

The good news is that the work is starting to pay off. The more historical draws I add, the more interesting the statistics and pattern analysis become.

It's one of those projects where 90% of the work happens behind the scenes and users only see the final result.

For anyone building a data-driven product, did the data end up being harder than the product itself?
