About this game

Sharpen Your Deduction Skills with Einstein Challenge – The Premier Logic Elimination Puzzle!

Dive into the world of pure logic puzzles, often dubbed Einstein's Riddle, Zebra Puzzle, or simply Logic Problems. This tick & cross elimination game, crafted by Rottz Games in 2013, turns logical clues into triumphant revelations through sheer brainpower.

Key Features That Set It Apart:
• Massive Free Content: Access over 5000 handcrafted riddles at no cost – no hidden packs or paywalls!
• Logical Solution: All riddles are guaranteed to have sufficient clues for solution! If you can't find yourself stuck, try restarting from another row.
• Fresh Daily Puzzles: Enjoy 15 exclusive challenges each day to train your mind on the go.
• Exciting Real-Time Multiplayer (Brand New!): Jump into live competitions where everyone solves the identical puzzle simultaneously.
• Leaderboard: Beat the clock for match-specific ranks and battle for the top spot on the monthly global leaderboard.
• Progressive Grid Challenges: Begin with easy 4x4 setups and advance to complex boards with hundreds of squares – difficulty scales with your expertise.
• Tutorial: For your first match a tutorial will guide you until you find the solution so you understand what you need to do.
• Expert Filtering Tools: Pinpoint hints tied to specific categories like jobs, pets, or habits for strategic breakthroughs.
• Seamless Mobile Design: Experience a fluid, touch-friendly interface with straightforward tick and cross mechanics – far superior to clunky paper grids with triangles.

In each riddle, you're presented with a intriguing setup: A group of individuals, each with unique traits like nationalities, favorite drinks, pets, sports, or accessories. Starting from clues such as "The Spaniard owns the dog. The coffee drinker lives next to the fox owner. The Norwegian resides in the red house...", your mission is to logically eliminate options and piece together the complete arrangement. It's an intelligence workout relying solely on deduction – no luck involved!

Perfect for fans of brain-teasing logic games; if sudoku or riddles are your jam, this will hook you instantly.

Slight learning curve might have been averted by looking at the directions, which I didn't. But once you know what the filters are for, how + and neg hints are green and red when they come up (respectively), a great little game & nice change from word logic puzzles. I've enjoyed it, but I haven't tried the more extreme levels. My only mild complaint is how tiny the icons are on a phone screen, but you can zoom in if you can't tell it is. I also wish there were more categories, but still love it!

This game has SO many levels to play, in multiple categories that fit whatever type of puzzle you want to play from easy to insane. I like the tile pictures the most; cute, simple and easy to see compared to other games that use text. All the puzzles are nice and challenging and with how many there are it's gonna take forever to get through just one category.

I first found this game in 2021, and it's now almost the new year 2025. And this is still one of my top three favorite logic puzzle games. I love Einstein/Zebra riddle games but word clues confuse me after playing for a bit. I love that I can focus on the images instead of written clues, as well as how this is laid out compared to other versions. The five difficulty levels are a plus as well.
