Privacy and Saved Games
You can play without creating an account or providing payment details or personal information.
What your browser saves
The game uses local storage to save the board, current and next pieces, score, high score, speed, starting rows, and sound preference. The Chinese and English pages share these records. They stay in this browser. You can clear them in your browser's site settings, which also removes your progress.
On the homepage, we use the language sent by your browser. When you choose CN or EN in the footer, a cookie remembers that choice for up to one year. Clearing site data also clears this preference.
Server logs
The server may keep access and error logs with request times, URLs, IP addresses, browser information, and response statuses to keep the site running and troubleshoot problems. This site uses no third-party advertising or analytics scripts.
Sound and external links
Your browser generates the sound effects without using a microphone or making a recording. The About page links to the reference game. Other websites have their own privacy policies.
When the browser can't save
Private browsing, storage restrictions, and clearing site data can affect saved records. If the game shows a storage warning, you may lose progress when you reload or close the page.
