This idea was developed into a mildly popular game in the early 90’s called Wordtris.

Here’s an example of the gameplay (Not my video): https://m.youtube.com/watch?v=EYO5WbBfp-E

The copyrights can be traced to Atari holdings, who also have a license for Tetris (who is turn pretty aggressively enforces the brand), so watch out for that.

Cool! When you think you have had an original thought turns out there is prior art.

Wordtris seems to be better featured; better distribution, list of completed words, eraser block, peek at next block and graphics :)
