The prompt

Make a falling-block puzzle in one HTML file. 10×20 grid, the seven classic pieces from a shuffled bag, a ghost piece, wall kicks and a short lock delay. Score more for multiple rows at once and speed up every 10 lines. Big touch buttons and swipe controls for phones, arrow keys on a computer. Save the best score on the device.

Claude wrote this game from a short brief like this one. It was then played, tested on phones and tuned before it went up here.

How to play

Full rows clear. Four at once is a Blockfall and scores the most.
The dashed outline shows where the piece will land.
Every 10 lines the pieces fall faster. The game ends when the stack reaches the top.
