This is a logic puzzle where you try to solve the tiles in each position of the grid. It is very similar to the puzzles where you figure out who lives in the blue house and they tell you that the person who owns a dog lives next door to the person who drinks tea. But with Einstein's Logic the clues are pictorial. You solve for the symbols in the grid, eg. the triangle is next to the letter A.
I have seen games like this called Einstein, Sherlock or Hercules. What I didn't see was a version for Android, so I made one. There are a couple other out there now, but I still like mine best.
