Gems can be collected.
The gems that fall below the highest level of the pieces, change the color of that line to that of the gem.
You can collect the gems that fall above the highest level, by clicking on the collected gem you can exchange it for the piece that falls and change the color of the line that interests you.
In the panel of the next piece there is a number that increases with each line completed by clicking on it we can generate another piece.
