In this episode of Brain Games, you'll see how your brain gets tripped up by odd angles, how light and shadows play a crucial role in your perception of the world, how you can radically shift the way you see reality, and how your brain isn't always as honest with you as you think. Through a series of games and experiments, you'll discover why you shouldn't always believe what you see.

On this beastly episode, it's going to be heads vs. tails as we pit humans against animals in series of unique competitions. And if you play along, you'll discover how a bird can eat like a horse, a dog can be jealous like a baby, and how a chimp can make you look like a chump. Who will win this interspecies showdown? Don't bet on the wrong horse.
