The game proposes to gradually group apples to make requested collections, in an adjustable interval between 2 to 10.
You have to store them in the lockers, then click on the bell in the target number is reached. Each correct answer earns a star.
Attention: if more than 12 apples are on the ground, the game is over.

For people with dyschomatopsia, it is possible to switch to monochrome mode.
It is also possible to click on Serge to alternate between the encrypted writing and the constellations of the dominoes type.

There are 4 difficulty levels.
In the first level, two kinds of apples fall from the tree every 4 seconds.
In level 2, there are now 3 kinds of apples.
In level 3, apples fall every 3 seconds. Any validation error on the bell drops an additional apple.
In level 4, apples fall every 2 seconds, and any mistake causes 2 more apples to fall.

To reset the scores, just click 5 times on Serge, or change the work interval.
