I have been collating my Amiga disks today and have a box full of Tetris games here. I have more sprinkled across computers, but three not mentioned there are..
Klacktris
Hot Blox
Dr Mario
Tettrix is spelt this way.. you can get it on Amiga Computing cover disk April 92 but its crap. There are the AGA versions Tetris.AGA Anglia PD G6060. and Giger tetris from 17 Bit Disk No 2994.. neither of these are what you are looking for.
Klacktris is the best to be honest.
I'll keep looking. I'm bound to have others. If you keep an eye on my games listing on the site you may see others.
