Poppy Playtime Chapter 1 is a first-person horror puzzle game set in an abandoned toy factory. You navigate the eerie environment using touch controls, solving environmental puzzles to uncover the facility's dark secrets. The core gameplay involves finding and using a special tool to interact with machinery and progress.

A key mechanic is the "GrabPack," a wearable toy arm used to solve physics-based puzzles. You aim and extend its hands via touch to retrieve distant items, pull levers, and conduct electricity. Stealth and careful observation are required to avoid a lurking entity.

The mobile experience is focused on atmospheric exploration, inventory-based puzzles, and tense evasion sequences, all adapted for touchscreen interaction. The story unfolds through discovered notes and visual clues scattered throughout the desolate factory.
