Darkball vs Ice Bot

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.

Push. Slide. Solve. No forced ads. No paywall. No timer. Every level included for free. Just you and the puzzle. Guide a small robot across handcrafted ice grids in a sliding puzzle where every push matters. Push colored crystal blocks and watch them glide until they hit a wall, another block, or a special obstacle. Match every block to its target in as few moves as possible. Start with simple slides. Then discover pushers that redirect blocks, obstacles you can crush, wildcards that match any target, and blocks that copy their neighbors. Every level is a handcrafted puzzle with its own twist. GENUINELY FREE All 60+ levels are completely free. Undo is unlimited. Skip, colorblind mode, and original music are all included. If you want a hint on a tricky level, you can earn gems by watching a short video — or grab a gem pack if you'd rather skip the ads entirely. PLAY YOUR WAY • No timer — think as long as you need • Unlimited undo — experiment freely and refine your solution • Hints when you're stuck — see which block to push next • Skip tricky levels — come back later • Colorblind mode — patterns distinguish block types 60+ LEVELS Handcrafted puzzles across three difficulty tiers — from gentle introductions to mind-bending challenges. Each one hand-designed with an optimal move count for perfectionists. SOUND & MOOD Original music composed for Ice Bot. Calm, cozy, and designed to help you focus. Headphones recommended.
