This is a really cool game sent to me recently. It is called Auditorium, and is made by a company called Cipher Prime. The goal is to move around the circular pucks on the board and change their radius to control the flow that is coming into the screen. When the flow enters the circular puck, it changes direction depending on the circle's symbol direction, position and size. If you can move the flow to hit the things that look like meters, they will start playing music.
Your goal, or problem, for each level is to light all of the meters up at once by directing the flow through them all at the same time. It is really, really fun and visually beautiful. I have been using it with some of my students, and it definitely tests their logical reasoning, problem solving and visual reasoning skills, while engaging them visually, tactially and aurally. From a teaching vantage point, the fact that there are many ways to solve a problem is great for mimicking real world problem solving, and could be used as a way to identify different learning styles across student populations by analyzing a student's solution paths.
In addition, one of the most interesting and useful areas of applied mathematics is that of DYNAMICAL SYSTEMS, which often deals with the behavior of fields and flows like we see in this game. This game setting offers a setting to introduce the idea of Curl (in two-dimensions at least), which can be one of the most difficult in multivariable calculus and dynamical systems. The puck pieces in Level 2 (Spring) with the crescent on them are actually curl creators -- they cause the flow to curl into a vortex, depending on the radius of the puck.
Writing an equation for how to control the degree of curling in the flow is an important part of understanding a number of physical systems, like fluid dynamics (Wikipedia) and bird flocking:
