Learn where countries are on the world map with Spaced Repetition
Hi HN, I made a web game to practice country locations a while ago and HN liked it, so I thought I'd post my updated version as well. As for how the game works and feels, I'd really recommend you checking it out for yourself, it's free, no signup, no ads. The tech stack is Vue + ts + Tailwind/Daisy for the looks. The learning algorithm is a slight modification of the ts version of FSRS. If you have anything to add, it's open source as well (https://github.com/koljapluemer/learn-worldmap), although not well documented yet. In the end it's just a little sideproject,…
In plain words
Learn where countries are on the world map with Spaced Repetition is a free web game that teaches users to identify country locations using spaced repetition learning techniques. Players answer questions about where countries are positioned without requiring signup or encountering advertisements. The application uses a modified version of the FSRS learning algorithm to optimize retention and review scheduling. Built with Vue, TypeScript, and Tailwind CSS, the tool is open source and allows users to practice geography interactively.
