Hidden Ball Cup Tracker

Watching the Shuffle

Each round begins with a ball placed beneath one of several identical cups. The cups then slide and swap positions across the screen. Your only task is to follow the cup that holds the ball. When the movement stops, you select the cup you believe is correct. A right choice adds points and sends you to the next round.

How Difficulty Grows

Early rounds keep things simple, often with just two or three cups and a handful of exchanges. As you progress, the cups move faster and the number of swaps increases. Later rounds add more cups and more complex shuffle patterns. This steady rise in speed and swap count means the challenge scales with your ability, so beginners and experienced players can both find a suitable level.

Clean Visuals and Clear Feedback

The game uses bright, uncluttered visuals with cups that are easy to tell apart. The shuffling animation is smooth, so your eyes can follow the movement without strain. A correct guess triggers a positive visual cue, while an incorrect guess gives a gentle reminder to refocus. The minimal interface keeps distractions low, letting you concentrate on the cups.

Short Rounds, Flexible Play

Every round lasts only a few seconds, which makes the game easy to fit into short breaks or longer practice sessions. There are no time limits, so you can pause and resume whenever you like. This design works for a quick mental warm-up or an extended session of observation training.

Who It Suits

The rules are simple enough for young children to grasp, yet the increasing complexity offers a satisfying challenge for adults. No reading or language skills are required, so the game is accessible to a global audience. It contains no inappropriate content, making it safe for all ages.
