Practice rounds use a random set and earn fewer points. Signed-in members bank points and share one daily challenge; guests play a separate warm-up round for fun. A round scores up to 50; each game banks up to 60 base points a day, before your tier multiplier. How points work.

About this game
A certificate of analysis (COA) is the lab report for a tested batch. COA Detective trains the three checks in the federal 2026 hemp definition: total THC including THCA on a dry-weight basis, total THC per container, and whether synthesized cannabinoids are declared. The numbers on each card sit right on the limits, because that is where mistakes happen.
Every card is graded by the same compliance check the marketplace runs on product listings, so the game and the platform can never disagree. Lab names are fictional and the cards are generated for practice — they are not real products.
This is a training game, not legal advice. State rules can be stricter than the federal definition: check the hemp laws and licensing for your state, or find a lab in the COA analysis directory.
