My strategy was just keep cramming more blocks in and wait. Eventually the pressure at the top forces the bottom line to rearrange and clear.

But I do think the threshold of complete line for the clearing of the bottom should be slightly lower to allow more frequent clearing. I think that would be an improvement that would also increase the playable fun duration.

PS I love this game I think it's very fun and maybe the tongue-in-cheek bylines should be "physically realistic Tetris"

I just noticed, as I think other commenters said, only the bottom line clears. I definitely think it would be an improvement, and I hope you consider, to allow other threshold complete lines to clear as well, as that would also I think increase the playable fun duration of the game.

You can drag blocks. When you make some place on bottom and there is enough blocks touching bottom to fill a line (it doesn't need to be continuous) all bottom touching blocks disappear.

I couldn't get dragging to work in Android chrome :(
