🎯 How to play

Every slide moves all the tiles as far as they can go.
Two tiles with the same number join into one worth double.
A new tile appears after every move that changed something.
A tile can only join once per move — four 2s become two 4s, not one 8.

🏆 Getting good

Pick a corner and keep your biggest tile there. Never move it out.
Use three directions and avoid the fourth — that keeps the big tile put.
Build a row in order along one edge: 2, 4, 8, 16…
The game is over only when there are no gaps and no equal neighbours.

🧑‍💻 This whole game is Python

There is almost no JavaScript on this page. The browser downloaded Pyodide — a complete Python interpreter compiled to WebAssembly — and then ran the .py files in funtime/pylib/. Python does the rules, the maths and the drawing.

File	What it does	Good functions to try re-writing
pylib/twenty48_rules.py	The rules: sliding, joining, turning	`slide_row`, `merge_row`, `rotate_board`, `move_board`
pylib/twenty48_draw.py	Painting the tiles — Python calling the canvas	`tile_look`, `draw_tile`, `render_game`
pylib/twenty48_web.py	The glue: the arrow keys and finger swipes	`do_action`, `on_touch_end`, `start_game`

🔍 Compare the two versions. Open lib/twenty48-rules.js and pylib/twenty48_rules.py side by side — same ideas, two languages.

🛠️ Build it yourself: Build 2048 in Python walks you through the functions one at a time.

⚠️ If the game never starts: the page has to read its .py files, which a browser will not do for a page opened straight off your disk. Use the live site, or run python3 -m http.server in the project folder.
