I used to play Tetris until the score was 99999.
Then I would reset the device to start playing again.
A simple game that had us Gen X and Ys obsessed in the 90s depended on an important visual perceptual skill - visual constancy.

To decide where a falling brick should go requires that we mentally manipulate the brick to quickly decide its orientation & where it should fit.

Well, not really.
There are non-dyslexics who may present with such challenges in visual constancy while some dyslexics don't.
Some individuals with dyslexia may have visual-perceptual issues that simply exacerbate their challenges in reading & writing. They have what we usually refer to as dyseidetic dyslexia or visual dyslexia.
Intervention will likely differ based on the etiology of one's difficulties.
A non-dyslexic with difficulties in visual perceptual skills often does not require literacy intervention. Instead, vision therapy may be more helpful.
Similarly, someone with dyslexia, who also presents with visual-perceptual challenges, will benefit from both literacy intervention & vision therapy.
