In Sink (2024)

Shapes, signs, numbers and mechanical controls give you something concrete to describe while your partner handles another part of the problem. The language-less puzzle elements are designed to be colour-blind friendly, and dynamic hints can help a stuck pair keep contributing. This is an online game for two players on separate devices, with a copy each. It is a good fit when you want a 3D escape adventure whose collaboration goes beyond one person spotting every answer.
