Spaceteam. It's iOS, it's free, and it's a co-op multiplayer game. Like, local multiplayer. You act as crew members of a starship trying to outrun a supernova, and every player gets a control panel full of switches, dials, and buttons. You also each get one instruction to follow, but the wired control might not be on your panel. So what we got was my wife, my daughter, and I all shouting nonsense sci-fi instructions at each other (Engage astro pipe! Vent Turing defibrillator! Rearrange deck chairs!).
It is totally great.
