Overview
An old laboratory holds messages written in the language of scent. Arrange seals, test your ideas and uncover the secret code one clue at a time. Every probe brings you closer to the answer.
Simple mode gives feedback for each seal; Classic mode offers a tougher deduction challenge. Explore 100 puzzles across 10 chapters, discover specimens, formulas, research and achievements, and restore the laboratory.
Play at your own pace on desktop or mobile. A guided tutorial, deduction notebook, text size controls, music settings and reduced motion help you settle in. Switch between English and Russian in the game.
