I made a 2 player browser game based on Pentago and janispritzkau's Loopover game (https://github.com/janispritzkau/loopover). Each turn you place a marble, then slide a row or column of the board. The first player to get five in a line (diagonal, vertical, or horizontal) wins. You can play the computer, someone you know with a shared link, or a random opponent online. It’s free with no sign-in required. Online play and play vs the computer are new, so please let me know about any bugs you find. It is built with TypeScript and Vue and uses Supabase for the online play.
