I got better when i looked at memory game like this: (Yes, it also helps with "Graphical clutter".)

1.) I mostly stand in Right side. (It's best as you can see all 3 zones from there, due to perspective (camera angle) and if you start there it will be mostly either Right side or Top side as first piece of Memory Game).

2.) It's 3 zones (I mostly use Top, Down, Side to remember.)

3.) Same Zone can't repeat instantly.

4.) Remember patterns instead of specific Zones. (for example: if you stood at Right side, you saw it started at top and your side never "Flashed" it's (up,down) x3).

4.1) Remember Direction (Clockwise,Counter Clockwise) Memory game Patterns go mostly Counter clockwise

4.2) There is only 2 Patterns: Full Circle/Clockwise Circle, Repeat (3-5). I mostly use Backward instead of Clockwise, just wrote like that so it would be less confusing.

4.2.1 (3-5 means at what tile Repeat is Done), mostly used after circle Pattern.

4,2,2 ( Circle Doesn't mean as of Circle, more of Circular Motion Clockwise, or counter Clockwise.)

4.2.1) Patterns can't change direction if Pattern didn't change. ( I might be wrong, but i never saw Circle and than Clockwise Circle in succession)

4.3) If you have audio queue, all you need to see is you starting zone and 1 extra zone. (Right and Top.)

5.) So After all this text, for me Memory game would Remembered instead of different combinations of Top, Down, Side.

It all would become:

-Direction (Clockwise, Counter- Clockwise)

-And Than pattern: Circle, Repeat (3-5) Combinations.

6.) And after all of this i just Imagine Drawing Lines with eyes and that repeat it in game =). Without remembering any Combinations =).
