Playgrounds
Interactive demos and sandboxes for Choice, Score, and Noul in the browser.
Paste state, mash buttons, watch probabilities move. Demos for skeptics and screenshot collectors. Playgrounds help you validate primitive combos before Jev touches billing or safety code. Many entries are static sites or sandboxes: still valuable for learning even when they are not production services. Submit yours if it teaches a pattern we have not filed.
