The gap
A sliding move makes lines hard to plan: a pebble only stops where something stops it, and the spawns change the board between turns.

What it solves
What it is
Every landing is computed and drawn before the flick, the tide is generated one turn ahead from a seeded generator kept in the save, and the hint bot plays each candidate on a copy (tide included) to judge the position it leaves.
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 turn-based grid puzzle, or any grid game that needs sliding moves, line detection with wildcards, scheduled spawns and a simple look-ahead computer player.
- Learning how a complete turn-based puzzle with stages, a daily mode, a menu standard and tests is built in plain JavaScript and Canvas 2D.
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
Rules on a plain object
The fen, the coming tide, the score, the stage goal and the generator's state live in one object, so the same functions run the game, the title scene, undo, saves and the Node tests.
A two-move look
The hint bot scores every flick by the lines it clears and the windows of one colour it fills, then plays the best two dozen on a copy, tide included, and keeps the one that leaves the best clear and the most room.
No build step
Plain JavaScript and Canvas 2D; open index.html through any static server and edit game.js.
Tests included
22 unit tests of the rules core (every stage reachable by the bot), 71 headless Chrome checks (keyboard, mouse, gamepad, phones by touch, menus, saves, both languages, sound levels) and a smoke test whose bot plays a stage.

Questions
Make and sell any number of your own games from it, and build games for clients. You may not resell or share the source code itself (PN Scripts Template Licence 1.0).
Any static web server to run the game, and some JavaScript. Node.js 22.12 or newer and Google Chrome run the smoke test.
No ad or portal SDK. The game text is in English and Bulgarian (a Language setting). It is tested in desktop Chrome and phone-sized Chrome viewports with touch (Pixel 7 held sideways, 750x342; upright shows a turn-sideways hint), not yet on iOS Safari, Firefox or a real phone.
The code was written with AI assistance and checked by PN Scripts with automated tests. All visuals and sounds are generated by code; there are no AI-generated image or audio files.
It is not on sale yet. When it is, this page will link to the store; PN Scripts does not take payment on this site.
