Education

Learn the real Linux terminal by living in Node City, 2061. Solve quests with real commands like ls, grep, find and pipes, drill them until your hands know them, then take night jobs in the Dark, where CivOS is hunting you and every command burns your cover.

Slide the blocks, clear the exit, and find the move that changes everything. Unblockme offers 1,800 puzzles across six difficulty levels, eight visual themes, undo, and saved progress.
