Tap the screen when you think the ball will appear in the target. The ball will only flash twice. The first flash happens when the ball drops and the second flash happens on the line. You’re goal is to tap the screen when you think the ball will appear in the orange target area. Cristiano Ronaldo can famously volley a corner kick in total darkness. The magic behind this remarkable feat is hidden in Cristiano’s brain which enables him to use advance cues to plan upcoming actions. Darkball challenges your brain to do the same, distilling that scenario into its simplest form - intercept a ball in the dark. All you see is all you need. One of the brain’s fundamental functions is to use information from the past and present to predict the future. This function is key to how animals, from dragonflies to humans, navigate a dynamic and uncertain world. To make predictions, the brain must have an “internal model” of the system it interacts with. A basic form of this function is at play when we move our body. For example, to reach for a cup, the brain must have a model to predict how the hand would respond to various motor commands. Internal models are also thought to play a crucial role when we mentally predict future states of the environment, for example when we track a ball as it moves behind another object. Here, we have designed a simple task to understand how the nervous system makes such predictions. In this task, subjects have to intercept a ball when it reaches its final position. By changing the speed of the ball, the intervals when it is invisible, and the target position, we will test various hypotheses about the algorithms that are used to integrate information about past and present to make predictions about future.

THE DRUMS OF WAR THUNDER IN THE TOY BIN Welcome to Green vs Tan. You are Green. They are Tan. This is a tower defense game fought with the plastic army men that used to live under the couch. A hundred to a bag. Stiff little soldiers on molded bases. You drag your troops onto the carpet, hold the line, and keep them off your toy box. EVERY TOY IS A UNIT YOU PLACE Ten kinds of soldiers wait in the bin. The rifleman is your guy. He shoots his rifle and he gets the job done. The machine gunner lays down heavy fire but moves like a slug. The minesweeper plants firecracker mines and defuses the enemy's. The bazooka man blows up groups of soldiers, boulders, and occasionally himself. Why not? That's just how it is. The mortar sits far back and drops shells that land exactly where you need them, or nowhere close. The flamethrower soldier gets in there and torches everything. He is dangerous in close quarters and even better when the fight thins out. The radio man calls in a paratrooper and boosts the troops around him. Discover more kinds of soldiers as you play. Every one of them promotes, a hundred ranks up. And Sarge is free, always. There is only one Sarge. BRING YOUR BUDDIES There are yetis to fight, dinosaurs to rule, secrets to uncover, and someone bigger waiting at the top. Over 100 levels to beat. Start a squad! Play real people in Battlefield mode, open a private room and pass the invite code around the house, or jump into a co-op campaign for up to ten and fight the bosses as a team. Beat a level and everyone's campaign moves forward. You can also play by yourself against the CPU at any size, all the way up to 10v10. No pressure. Bring the whole friend group, the whole family, or your local army commanders. BEFORE YOU ENLIST Green vs Tan is free to play, and nothing is locked behind money. Every star can be won on the carpet.
