Blinken is the ultimate memory game, though you need not possess the ultimate memory to be successful. These tips will help you in your pursuit of the best score:
If you have PC speakers, turn them on with the sound at a good level so that you can hear the tones alongside seeing the flashing lights.
Experiment with both the mouse and keyboard interaction methods, to see which one suites your memory best.
Try remembering the sequence as a list of colors.
Try remembering the sequence as positions on the screen.
