A polished vanilla-web implementation of the ancient Indian board game. Supports local multiplayer, computer opponents with three difficulty levels, 5x5 and 7x7 boards, animated kaudi toss, synthesized audio, and offline install as a PWA.
Also known as:
Changa Asta has been played across Karnataka, Andhra Pradesh, and Tamil Nadu for centuries. It has no single authoritative digital version. Most implementations are either unpolished ports or miss key rule variants like Gatti blockades.
Both 5x5 (4 kaudis) and 7x7 (6 kaudis) boards are implemented with correct roll tables, safe squares, inner path entry conditions, and optional Gatti blockade rules — toggle individually in-game.
Built entirely with HTML5, CSS3, and ES6 JavaScript — no framework, no bundler. The service worker enables offline play. A procedural favicon animates in the browser tab during play.
Features
localStorageCore rules
Pawns travel around the outer ring from their starting side. A player may enter the inner path toward the home square only after capturing at least one opponent pawn.
Rolling a high or extra value (8 on 5×5, 12 on 7×7) grants another roll. Three consecutive extra rolls cancel the turn and pass play to the next player.
When enabled, two same-color pawns on the same non-goal square form a Gatti. Opponents cannot pass or land on it unless they arrive with their own Gatti.
Player start positions
Kaudi roll values
Roll value is determined by how many kaudis land mouth-up.
