Know Your Numbers
yer a math wizard, harry!
Know Your Numbers launched on April 26, 2020. The site was still online in September 2026, 6 years on.
What it does
The game is a simple number game. A number is shown on the board and you have to say whether it is prime or not. If it is prime, click the RED button, if not then click the BLUE button! And oh, you get only 5 seconds to click or you lose. Sounds simple?

I'm challenging your clicking speed with this game I rebuilt2022 · projects.marcnitzsche.de · ▲25Hello HN, last week, I stumbled over an old project of mine called Click The Number. I built it about six years ago to compare my clicking and reaction speed with that of my friends. The idea is simple – just click on the numbers in orders as fast as possible. I couldn't resist and rebuilt a lot of parts again, making them a bit nicer. I updated the design and added some features like a personal high score.

https://github.com/OlexG/finclaw ^ repo if anyone wants to contribute. I realized that sometimes I'm pretty good at making random guesses about the future. (I.E, I think OpenAI will beat Anthropic in the short term, etc...) However, I'm bad at converting these guesses into actual market plays I can profit from. As such, I wanted to make a tool that connects to the right APIs and launches a swarm of agent experts to generate related plays based on your prediction. The very first super shitty V0 MPV just has Polymarket/Kalshi bets, but I will be adding a more complex…
