Slidey game

Hey everyone,

I'm fairly new to programming and just getting started with learning python.

As a project to speed up the learning process, I'm trying build a simple version of the Slidey game (similar in some ways to the Tetris).

I now have to the decide which structure to use to store the information of my blocks (length, type, color). I have no clue on how to decide what the best and most efficient option is.

Somebody who could give me some tips to solve this problem?

Kind regards

Rob
