The gap
A chess game needs strict rules, a believable engine that stays responsive in the browser and a board interface that works by touch.
What it is
This template gives you a tested 5x5 rules core, a tunable alpha-beta engine and a polished touch and keyboard board around them.
How you use it
Unzip, serve the folder and open index.html, then edit game.js; npm test plays it again in headless Chrome.
Source code of a real, playable game to reskin and learn from, with a smoke test whose bot plays it.
Use it when
Built for
Engine.think() runs iterative deepening with a node limit, so strength and response time are two numbers in LEVELS.
gen(), attacked() and legal() hold the whole rule set; change the setup in startBoard() to try other minichess variants.
Plain JavaScript and Canvas 2D; open index.html through any static server and edit game.js.
A headless Chrome test loads the game, checks the console, presses keys and taps, and lets the built-in bot play a run to its result screen.
