PuzzleForge on the web is built the same way as our iOS apps: private by design.
Your work stays on this device
Your progress — best scores and XP — is stored only in this browser (on-device storage). It is never sent anywhere. Clear your browser data and it's gone; nobody else can see it.
No accounts, no ads, no tracking
There is no sign-up and no login. There are no ads and no in-app purchases. There are no third-party trackers. Every puzzle runs entirely on this device.

The 400 Concepts questions come straight from the PuzzleForge iOS design. A wrong answer is framed as a pattern to spot next time, never a scold, and a hint appears only after a first try. The four playable puzzles all run on real, checked rules — a scramble is never impossible unless we tell you it is.
