## What is Ka?

Ka-Boom-y is a hypnotic physics game that's impossible to put down.
Drop balls into any shape and watch them bounce. When two balls collide — KABOOM! They multiply. Set your multiplier, choose your shape, and see how long before the chaos takes over and fills the shape.

DRAW ANYTHING
Ka-Boom-y's custom drawing tool lets you create any shape you can imagine. Draw spirals, mazes, letters, or anything in between. The more creative your shape, the longer the suspense before the KABOOM.

COMPETE WITH FRIENDS
Every game is timed. How long before the first KABOOM? How fast until max balls? Compare times with friends on the same shape and see who can design the shape that survives the longest.

SHAPES FOR EVERY MOOD
Choose from 9 built-in shapes — circle, square, hexagon, triangle, hourglass, dumbbell, blob, arena, and maze. Each one creates a completely different experience.
