----
The goal is to store as many blocks as you can. Red give 1 pt, Green 2 pt, Blue 3pt and Yellow 4pt. 
Click on a block to store it to the block list.. 
Storing 3 consecutive blocks of the same value will merge them into one block with triple value.
The more blocks you store, the fewer will be the mean score and the more blocks you combine, the more will be the mean score
Game ends when a block reaches below the stage
