About In Sink

In Sink is a two-player co-op game about escaping a series of puzzle-filled rooms. After being shipwrecked, you and a partner travel through rifts to other worlds, solving puzzles and mysteries together to find a way out.

Worlds and levels

Your journey takes you through eight levels, including a hidden pirate ship, a mysterious art museum and a train that defies the laws of physics. Each setting contains puzzles and challenges to overcome as a team.

Solve puzzles together

You and your partner must act as each other’s eyes and ears. The puzzles use language-free elements such as shapes, signs, colours and numbers, and are designed to be colour-blind friendly. You turn wheels, flip levers, use scales, and press buttons and pressure plates to solve the challenges.

The game has simple, accessible controls and a dynamic hint system that offers help without revealing solutions.
