Recently updated my old Rock-Paper-Scissors website Roshambo.me to version 3.0.
Main new features are a responsive design and support for Rock-Paper-Scissors-Lizard-Spock. On the backend the site has been rewritten from scratch in Phalcon and the database heavily optimised.
The original website was a small experiment made while learning python almost a decade ago. It was never designed to handle over 10,000 users and 100,000 completed games.
With the new, faster engine it will now be possible to add more features - so version 3.1 coming soon.
