Rotate Cups

Five minutes with Rotate Cups and you're already mid-tilt, watching a ball slide off one clear cup and drop straight into the next, hunting the exact angle that turns a cup into a ramp instead of a wall.

The rule is simple: get every ball into a blue cup lower on the screen. Bigger blue cups hold several balls, smaller ones each need their own, and the clear cups in between are just there to be rotated clockwise or counterclockwise until gravity does the rest.

Nothing here is timed, so you can spin a cup back and forth as many times as you want, pause when you need to, and think through the physics instead of racing a clock. It plays well on Android, iOS or desktop right in the browser, no download involved.

If you like puzzles that reward patient thinking over fast reflexes, it sits nicely alongside other Puzzle games on the site, and fans of Brain Training Games will recognize the same kind of quiet, one-step-at-a-time satisfaction.

Get at least one ball into every blue cup on the level - bigger blue cups can hold more than one, and if there are several small blue cups, each one needs its own ball.

On desktop, left-click and drag to rotate: drag left or down to spin clockwise, right or up for counterclockwise. On touchscreens, tap and drag your finger across the screen to rotate the cups the same way.

Levels aren't timed, so rotate as many times as you like and pause whenever you need to. Watch how the ball rolls off each clear cup before committing to your next spin - small angle changes make a big difference.
