Helio-3 The Lab

Atom reactions

Helio-3 The Lab is a single-player incremental idle and merge game for PC. You move colored atoms around a laboratory board, making them collide, merge into larger elements, or split through fission. Each merge unlocks the next element and earns points.

You can inject more nuclei, then attract, repel, launch, and reposition atoms like billiard balls. Tapping can also make atoms collide, merge, or break apart. Active abilities speed up progress, while passive abilities add another way to build it.
