It reminds me of sudoku with a story line. And I can overlook the occasional grammatical error (subject verb agreement, etc.). But as you move on in the game, clue errors start to appear, which voids the logic and kills the fun. For example, "Only blond-haired people in Column B are innocent." So you select a brown-haired person as guilty, but that turns out to be wrong. I'm on Level 139 and this is my fourth game with an error. I think the first 50 rounds or so were error free as fast as clues go, so it's fun for a few weeks. Even more mistakes as you go on. Turns from a fun escape to frustration. I don't understand how it's so hard to get a kid who's proficient in English to play the game and help you find your errors. Pay her a bonus for every mistake she uncovers. ### 3/5 — Started out fun but devs got careless in higher levels *2026-01-22* I enjoy this game. It reminds me of sudoku with a story line.

Still, I passed every level. It’s fun to pass the time. ### 3/5 — Fun way to pass the time *2025-12-02* The grammar on a lot of the clues is downright awful and misleading, but it’s ok if you don’t take the game too seriously. The ads play after every round, but thankfully don’t interrupt gameplay. It’s true this is a knock off/carbon copy of another game on the App Store, but most games on here are. They all reuse assets or game engines. If you can overlook these things, it’s fun. ### 4/5 — Fun way to pass the time *2025-11-21* The grammar on a lot of the clues are bad and sometimes outright unhelpful, but it’s ok if you don’t take the game too seriously. The ads play after every round, but thankfully don’t interrupt gameplay. It’s true this is a knock off/carbon copy of another game on the App Store, but most games on here are. They all reuse assets or game engines. If you can overlook these things, it’s fun. ### 1/5 — Text too small *2025-11-21* The text is too small and clues are often written wrong, don’t waste your time downloading this. ### 1/5 — Game *2025-11-19* This game would be wonderful if was full screen on my iPad. But unfortunately it isn’t so I will be deleting it. ### 5/5 — Only complaint *2025-11-02* The print is too small. Eliminate some of the top heading. Otherwise it’s great! **Developer response:** Thank you so much! We're thrilled you think it's great. Regarding the small text, we are already working on a design update to improve this. As a temporary solution, you can long-press on character cards to magnify them. We appreciate your suggestion! ### 1/5 — Daily puzzle clues are often untrue *2025-10-11* The daily puzzles are poorly written, most clues are the exact opposite of what they say. “All diagonal neighbors of x are good” and 3/4 are villains? **Developer response:** Thank you for your feedback. We’ve looked into the puzzles you mentioned and found that some of the earlier levels did contain misleading or incorrect clues. We’ve fixed these issues in the latest update. We appreciate you pointing this out and hope you’ll give the updated version a try. ### 1/5 — Don't bother!! *2025-10-06* A good portion of the clues are incorrect, leading to the player incorrectly choosing them as "good" or "bad". Boys sometimes have girl names and pink backgrounds, and vice versa. I love this type of logic game, but this one needs a HUGE amount of rewriting. Go download the Clue Master instead. I'm 100% sure the 5 star reviews on this game are fake. **Developer response:** Thank you for taking the time to provide such detailed feedback. We sincerely apologize for the frustration caused by the incorrect clues and inconsistencies, such as the character names and backgrounds not matching their logic. We want to assure you that we have invested significant effort into a comprehensive review and revision of our puzzles. In the latest updates, we have rewritten a huge portion of the clues to ensure they are accurate and logically sound. The issues you mentioned, including the gender/name mismatches, have been a key focus for our team, and we are confident that the current version provides a much more coherent and fair logic-puzzle experience. We are genuinely committed to improving the game and are sorry that your initial experience did not meet expectations. We hope you might consider giving the updated version another chance. ## Frequently asked questions about Logic Master ### What is Logic Master: Card Detective?
