About

Einstein Riddle Megamix

Features
Read full description

Einstein Riddle Megamix is a logical puzzle inspired by the well-known Einstein’s Riddle (also known as the Zebra Puzzle or Logic Elimination). Unlike the original, this game offers four different versions, each with a unique twist. The first version follows the classic format: each row represents a distinct set of items (such as fruits, animals, cars, etc.). You are given a list of clues like “The apple is to the left of the rabbit,” “The car is in the same column as the book,” or “The duck is next to the bottle.” Using deductive reasoning, you gradually determine the correct positions of all items. By piecing together the clues step by step, you eventually arrive at the complete solution. Each riddle has a single, unique answer. The other three versions build on the same logical foundation but introduce new gameplay mechanics. In one variation, the icons are scattered randomly across the board rather than organized in rows. Another uses the same set of icons for all groups. The final version features just one set of icons shared across the entire board. Each variation offers a distinct and refreshing gameplay experience. Game Features - Thousands of riddles in various sizes, from easy to truly challenging - Four distinct versions of the puzzle, each offering a unique gameplay experience - Daily Challenge featuring 16 brand-new puzzles every day - Weekly Challenge with 40 fresh, unique puzzles each week - Play anytime - no internet connection needed - Intuitive system for tracking your progress toward the solution - Clues presented both visually and with written descriptions How to Play - Start by checking the clues to get initial hints about item placement. - Click on a clue, then tap the “?” icon for a detailed written explanation of the pictograms. - Use the clues and logical deduction to eliminate possibilities and determine the correct locations of the items. - Once you're sure about an item's position, click on the cell and place the item. - Place all items correctly to solve the puzzle and win the game! If you enjoy puzzles, riddles, and logic challenges, this game is just what you're looking for!
