How Labdle works

A fictional laboratory report comes back one result release at a time. Each incorrect diagnosis releases the next result — solve the pattern within five. Every released case stays playable in the Result History, and a free Rounds account keeps your streak and statistics in sync across devices. Labdle is one of four daily games by Rounds.
