SMP Snake is a simple snake game played on a retro looking monochrome, text only "terminal" display. This display is intended to resemble the monochrome, CRT phosphor displays from the late 1970s and early 1980s. Colors available are green, amber, white, and a high contrast yellow mode for those who have difficulty seeing in the other three modes.

SMP Snake supports Google Play Games achievements and leaderboards. If you aren't signed in automatically, use the SIGNIN command from the menu.
