then for instructions like cls, setOrigin etc. are already on blitz 2 or need to use other ones?

Yes, the read-Data is basic BASIC. Please note: Blockcolor is in 24bits (255 values for red/green/blue). So you need AGA display or RTG.

Forget SeedRnd, you don't need it. This is for internal use of the random number generator. Just replace the

NextPiece = Rand(1, 7)

with

NextPiece = RND(6)+1

and you are good.

Note the brackets. You cannot declare anything of the arguments inside the function arguments. And: Any variable listed as GLOBAL variable on top of the source present in your Function or Statement must be declared inside the Function with SHARED before using it. Otherwise it is 0.
Note: there is a

  If .... Then Return

inside this Function.
You can (for now) just replace the Return with

Statement Return

(Normally, you have to "Pop" too. Doesn't matter now.

Plus, am planning to use shapes and not drawn blocks: how much the logic might differ?

You can draw the blocks to create your own shapes once and save/load them later. Or you use a paint program. Or you start to use the block drawing and change that later. But this is headache, donot start with this. Try to make it run first, let it compile and see what happens.
Reason: You have to change the logic quite a bit. I would start to replace the little "DrawBlk" Function with a simple "Box", with adaptions for color, of course. this would speed up things a little bit if you after this.
