Tetris and games that require dynamic screen movement are not currently very likely on e-INK devices. The update time is not zero or even short requiring nearly a second to redraw the screen. Other programs have already appeared for Sony devices, some iRex devices, and the open OS that currently can be added to the Jinke device.
The answer is a selective yes, so long as you use something that lends itself to e-INK display.
