I used to play TwinTris on the Amiga a lot: one the best version of Twintris ever (there are several videos on YouTube showing it). Very smooth 50 frames per second "pixel perfect" animation (but that doesn't translate very well in a YouTube video) and an amazing soundtrack. But I was "too good" at it: there were vertical bars showing how many of each piece got randomly selected and these bars would grow higher and higher as you were playing. I was playing for so long, even when the game reached crazy speed, that the bar would arrive at the top of the screen and then come back down, a bit shifted. A major video memory corruption would follow and it was only getting worse and worse. At one point it became impossible to correctly see the screen and you had "lost" to the display bug. : )
