It won’t eat your battery if you are looking for something to play on a long flight. It might take a few games before you understand the clues, but worth it once you do, especially if you like pattern matching logic games. Do the lower levels only to learn the clue patterns. The real game is the hardest level. ### 3/5 — It’s a good effort *2019-01-13* If you’re looking for mastermind this is close ### 5/5 — Terrific fun, challenging, logic skill builder *2017-08-03* I love this game! You have to develop a methodical pattern of testing. Each level helps you learn the logic skill to use in the next level. Hint: start with all one color, and test color by color. If you're methodical and consistent, you can win every game. As more colors and patterns are introduced you have to adjust your method. You can often figure out where a color or pattern has to be. With enough skill I think you can win every game. The number of guesses increases with each level. Thanks for hours of fun, game makers!!! ### 5/5 — Deductive reasoning *2017-05-07* I love this game! Remember the logic puzzles you played in school? One can think of it has guessing if you don't use deductive reasoning but I always liked those games so if you are into that, this game is right up your alley! Pretty addictive too. ### 5/5 — Fantastic logic puzzle! *2017-05-01* I love this game! Definitely a challenge. It's all a process of elimination (like sudoku and other logic puzzles). I like that there's an option for hints if wanted/needed, but there's no real "handholding". I always end up playing more than one game whenever I open the app XD ### 5/5 — Challenging and fun! *2017-05-01* If you like challenges and puzzles, this is the game for you! It's hard to find games that actually make you sit and think about your next move, and how it will affect the out come. Highly addictive I recommend this to anyone who likes a good challenge. ### 5/5 — New Favorite *2017-04-29* If you want a change from Sudoku, this is the game! Not easy but if you like logic puzzles this will challenge you. Best advice I got from my friend who recommended this is, "Make a guess and proceed from there. Even if you get no clues, it's still a clue that eliminates that color and shape." Now, I'm on at the Grand Master level!!! Awesome game! ### 1/5 — Logic??? *2017-04-27* I don't understand the instructions nor see what logic has to do with playing the game. The very first game in easy mode does not make sense at all. Seems like just a bunch of guessing. ### 5/5 — Grand Master Level Is the Best *2014-01-11* Forget the lower levels, the grand master level is the one to play! The very definition of logical puzzles. Challenging with a secret feature not available in the lower level puzzles. Won't give it out here but you'll love the surprise! ### 5/5 — Spock would get addicted *2013-09-01* This game really challenges your logical thinking. Can't get enough and moving on to the paid version. Think I can do it!!! ## Frequently asked questions about Syllogism ### What is Syllogism?
