It will keep giving you that piece until you threaten to get a line using only that piece.

Haha, it gives you an S (Z), except when you are about to fill up a line. (place SSSSS together, filling the bottom space). Then it gives you a I. At some point it gave me an L and a J. The darn thing is really mischievous!

You spelled Monotonous wrong ;) It basically gives you the worst piece (Z) every time unless there's another worst piece. I got a 4 bar line OOOO and also an L once.

Overall I just wasn't impressed. It reminds me of the level of tetris you'd reach after beating all the easier levels only to find that you got to the level that the game creators decided nobody could ever win because they didn't write an ending sequence.

I mean, it does exactly what it set out to do. It wasn’t meant to be fun.

If you think it's broken, then you should try to clear some lines, I dare you! >:D
