Youzu

A maths and skill game for the whole family.

Youzu is an Android game that blends mental arithmetic and physics. Spheres in five colors, each with its own weight, fall into a spinning drum. Hit the requested weight exactly to open the trapdoor and move on to the next level.

The game works entirely offline, has no ads and no in-app purchases, asks for no permissions and collects no personal data.

How to play

• Tap a sphere in your reserve, at the top of the screen, to drop it into the drum.

• Each color has its own weight: 1, 2, 3, 5 or 8.

• Hit the requested weight exactly: the drum's trapdoor opens and you move on to the next level.

• Too heavy? You lose a life and the level starts again.

• At each level, new spheres join your reserve: count carefully before you drop!

The spheres

Each color always has the same weight, and the heavier spheres are a little bigger. In Challenge mode, the weights are no longer written on the spheres: remember the colors!

• 1 Red
• 2 Yellow
• 3 Green
• 5 Blue
• 8 Purple

• The silver sphere

  It may hide in a lot or among the spheres in the drum. It does not count towards the weight, but it is worth 100 points if it falls out of the drum while the trapdoor is open. If it is still inside when the trapdoor closes, it breaks.

Game modes

• Normal

  At your own pace, with 3 lives. At each level, pick one of 3 surprise bags (light, medium or heavy) to pour into the drum. Once the trapdoor opens, the spheres that fall out join your reserve.

• Timed

  Hit the weight before the countdown ends: 30 seconds at level 1, then one second less at each level, down to 12 seconds. The requested weight can always be reached with your reserve.

• Challenge

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

• My records

  Your 20 best games in each mode (score, level reached and date), saved only on your device.

Points

In Normal and Timed modes, each level cleared is worth 25 points, and each silver sphere that falls out of the drum is worth 100 more.

In Challenge mode, a level cleared is worth 10 points per unit of requested weight plus 20 points per level, all multiplied by 2.
