Difficulty
Balls fall slowly and there's less poop. Great for a first try.
Press "Open the door" and balls fall from the top. Move the basket left and right to catch them! Catch the poop (💩) and it's game over. Grab a star (⭐) and it auto-catches for a while.
Catch Drop is a reflex, dynamic-vision and focus game where you catch falling balls in a basket, and it runs entirely in your browser. "Dynamic vision" here means the ability to keep tracking a moving object with your eyes; following a falling ball, predicting where it will land, and lining your hand (the basket) up with it is hand-eye coordination itself — the foundation for physical activities like ball sports and cycling. Open the door and colorful balls start dropping from the top one after another. Move the basket left and right to catch them and your score goes up — and every catch makes the balls fall a little faster. That's an adaptive difficulty: the better you get, the faster it runs, so you're always playing right at the edge of your reaction speed. On top of that, catch the poop (💩) mixed in among the balls and it's game over. Telling "good to grab" from "must dodge" in an instant, and holding back the urge to reach for the wrong one, is a go / no-go task that exercises the brain's inhibition (impulse control) — so you train not just moving fast, but the judgment to stop a movement too. Grab a star (⭐) that shows up now and then and the basket automatically chases and catches balls for a short time, safe from poop while it lasts (auto mode) — a little breather, too. Controls are just a mouse or touch drag, or the ← → keys, so even young children can play. Three difficulty levels change the starting speed, spawn interval and how much poop appears, and your best score is saved per difficulty.
Practicing reflexes and dynamic vision
See a falling ball and move the basket fast — a rhythmic loop of look, decide, and move.
Building focus
The speed keeps creeping up, so it trains your ability to stay concentrated all the way to the end.
Sharpening quick judgment
You tell balls to grab from poop to dodge in a split second, training how fast you decide.
Play for younger children
You just move the basket left and right, and the rules are simple, so anyone can start right away.
Stepping up little by little
Move from Easy to Hard and the speed and the amount of poop both increase, so you can level up as you improve.
A quick break
Each round is short, so it's great for a few minutes of play to refresh your mind.
Catch Drop runs entirely in your browser. It makes no external connections, uploads nothing, and uses no sound or image files (sound effects are synthesized on the fly with Web Audio, the balls, basket and door are drawn with CSS, and the poop and star are emoji). The only thing saved is your best score per difficulty, stored only in your device's localStorage.
