Fill The Cup 3: Frost is a physics-based puzzle game where players guide water from a pipe into a cup. By holding a button, water flows and reacts to the environment, requiring players to overcome obstacles such as spikes, portals, moving platforms, and more. The game introduces freezing zones that allow players to freeze water and create solid paths to help redirect the flow into the cup. Each level includes a collectible snowflake that challenges players to complete the level perfectly. With simple controls, colorful cartoon visuals, and increasingly challenging puzzles, the game is suitable for children and casual puzzle players.
