We use Google Analytics 4 to understand visits and how people use this site. When you visit, your browser loads the Google tag from Google and sends usage data to Google Analytics. Google Analytics may set first-party cookies, including _ga, to distinguish visitors and sessions. We do not add puzzle board values to Google Analytics events.

We also use Microsoft Clarity to understand clicks, scrolling, and other page interactions through heatmaps and session replays. Your browser sends page display and interaction data to Microsoft. Clarity may set cookies, including _clck and _clsk. Input fields are masked in Clarity recordings, but board positions shown on the page may appear in a replay.
