AtomLink

AtomLink is a puzzle game where you transform basic chemical bonding knowledge into intuitive connection challenges. A central core atom is displayed on your screen, surrounded by waiting peripheral atoms or functional groups. Your objective is to correctly draw covalent bonds between the atoms before the 60-second timer runs out.

Each atom has a specific valence that limits its number of connections. By long-pressing and dragging, you can create single bonds between atoms. A quick double tap on an existing single bond will attempt to upgrade it to a double bond, provided the atoms' remaining connection capacities allow it. Be careful, as incorrect connections will cause the lines to break and result in a 5-second time penalty.

The game features two distinct modes:
- Tutorial Levels: Progress through 30 distinct stages, starting from simple molecules like Methane and gradually advancing to more complex structures.
- Laboratory Mode: Test your skills against a random generation algorithm. A central atom and various peripheral units are randomly selected and precalculated to guarantee a valid molecular structure solution. Their initial positions are scattered, leaving it up to you to figure out the right bonds.

Track your progress through the Encyclopedia, which records all your completed molecular structures along with your fastest completion times.
