Choose your game mode!

Normal

At your own pace, with 3 lives and a surprise lot to pour into the drum at each level.

Timed

Hit the weight before the countdown ends: 30 seconds at the first level, down to 12 seconds later on.

Challenge

A single life, hidden weights and a drum that speeds up and changes direction. Points count double!

A spinning drum and colored spheres.

Easy to learn, hard to put down.

A target weight is shown. Tap a sphere in your reserve to drop it into the spinning drum. When the weight is reached exactly, the trapdoor opens and you move on to the next level. Too heavy? You lose a life and the level starts again.

Five colors, five weights.

1, 2, 3, 5 or 8: time to count!

Red, yellow, green, blue, purple: each color always has the same weight, and the heavier ones are a little bigger. Watch out for the silver sphere too: it weighs nothing, but it is worth 100 points if it falls out of the drum while the trapdoor is open. Otherwise, it breaks!

Three modes: Normal, Timed and Challenge.

And your records, mode by mode.

Play at your own pace in Normal mode, beat the countdown in Timed mode or try the Challenge: a single life, weights no longer written on the spheres and a drum that speeds up and changes direction at each level. Your 20 best games in each mode are kept on your device.
