The gap
Players lose trust when a puzzle's star target is not actually reachable, or far too easy.

What it solves
What it is
Every yard ships with its true minimum from breadth-first search, and hints are computed live from the player's position.
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.
Who it is for
Use it when
- Publishing a sliding-block puzzle, or any grid puzzle that needs exact optimal move counts.
- Learning how a complete sliding unblock puzzle is built in plain JavaScript and Canvas 2D.
- Building a branded mini-game for a client.
Built for
- Web and indie game developers who know some JavaScript.
- Developers who want a finished, tested game to build on instead of a blank canvas.
What you get
Hard yards by hill climbing
Random yards rarely need more than twenty moves, so the hardest ones were mutated (a cart added, removed or a haystack moved) and kept whenever the search showed they still needed as many moves or more.
A move is a slide
The search and the move counter agree: sliding one cart any distance is one move, and consecutive slides of the same cart are merged, so the score matches the minimum the search reports.
No build step
Plain JavaScript and Canvas 2D; open index.html through any static server and edit game.js.
A smoke test
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.
