Ball Drop: Call It

Where will it land?

Call It is a calm physics prediction puzzle. A ball waits at the top of a course of ramps, bumpers and cushions. Slide your marker along the finish strip to the exact spot where you think the ball will first touch it, then tap Drop it! and watch.

One ball, one course, one prediction

• The whole course is visible before the drop: nothing hidden, no luck added
• Every object shows what it does: shiny bounces, matte absorbs, striped launches
• The same course always gives the same fall, on every device
• Your gap is always shown in centimeters, hit or miss
• Missed by a hair? So close! Tap Next challenge or Retry right away
• Watch the fall again in slow motion, with the full trajectory and every impact

60 handmade challenges in 4 worlds

Ramps, Bumpers & Cushions, Trampolines and Seesaws. Each world teaches one new object, then mixes them into trickier courses. Earn up to 3 stars per challenge and a bronze, silver or gold badge per world. Only your first prediction counts for stars; retrying is free practice.
