Rootlings: Secrets of the Depths is a free online game where you guide a growing root downward through an underground world, collecting water and dodging hazards along the way. The levels are filled with surprises, and the challenge scales to keep both casual and determined players engaged. The game runs on phone or computer, making it easy to pick up wherever you are.
The goal in each level is to collect water while steering clear of rocks and sand. Gathering water lets you reach the end of the level, and coins picked up along the way can be spent on stylish hats.
