Tetris Similar Game

I'm new here and just getting around to installing a few games on my iPad 2. Recently I saw an article but can't find it now on a game very similar to TETRIS. The chap testing it said, in his opinion, he thought it was even better than TETRIS. I meant to look for it through I Tune Apps but I can't remember the name of it.

Could somebody help me? The chap playing it found it even more challenging than TETRIS but it was very much like it.

I hope it was alright to post this new thread here. I think it came to me through an E mail, possibly Pad Gadget but I can't be sure.

Sounds like Pentix.
