Turtle
From OGame Wiki
A turtle or turtling refers in OGame to a defensive playing-style, with focus on strong defenses, rather than large fleets. This large build of defense allows for a more 'relaxed' playing style, decreasing the possibility of worrying over possible fleet losses.
Turtles come in many shapes and sizes, depending mainly on the age of the universe in question. The largest turtles in the oldest universes has up to a million units of defense on one planet, whereas the turtles of the newer universes have merely 2000 units on one planet.
Often, the larger turtles have discovered that building Death Stars behind a huge wall of defensive fodder creates an almost impregnable wall, behind which you can hold off even the largest fleets in the universe.
