Einstein Riddle – unique text-based brain puzzles designed to boost your IQ.
Einstein's Riddle is a famous logic puzzle that, according to legend, was created by Albert Einstein in his childhood. He reportedly used it to test logical thinking skills in candidates for assistant roles.
Einstein claimed that only two percent of the world's population can mentally process the puzzle’s five clues using pure logic. As a result, this challenging puzzle can be solved entirely in one's head—without paper—only by those who belong to that two percent.
In its most difficult form, the puzzle must be solved mentally, without any aids for recording information.
Solving it requires a series of deductive steps. By entering known relationships into a mental table and consistently eliminating impossible options, you eventually arrive at a complete solution.
