⌨️ Controls

Click or tap a pad — or use 1 2 3 4
Q W A S work too, as do the arrow keys
P pause • R new game
Presses during the flashing are ignored — wait for YOUR TURN.
🎮 Xbox controller? Just plug it in or pair it — the stick and D-pad are the arrow keys, A is SPACE, Menu pauses and View starts again

🎯 How to play

The game flashes a pattern of pads. Watch carefully.
When it says YOUR TURN, press the same pads in the same order.
Get it right and the pattern grows by one and flashes again.
One wrong pad ends the game — so take your time on the early rounds.

🏆 Scoring

Finishing a round is worth 10 × the round number.
Round 1 flashes each pad for 620 ms; by round 15 it is down to 260.
Most people manage 5 or 6. Ten is genuinely impressive.
Tip: say the numbers out loud as they flash. It really works.

🧑‍💻 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/simon_rules.py	The rules: the sequence, the checking, the phases	`add_step`, `is_correct_so_far`, `press_pad`, `update_game`
pylib/simon_draw.py	Painting the pads — Python calling the canvas	`draw_pad`, `pad_at_pixel`, `render_game`
pylib/simon_web.py	The glue: clicks, keyboard, the loop	`do_action`, `on_board_click`, `frame`

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

🛠️ Build it yourself: Build Simon Says 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.
