Easybrain's Logic Puzzles - Clue Game occupies a specific niche within the mobile board game category, focusing exclusively on the deduction puzzles often found in puzzle magazines. The app presents players with a scenario—like matching chefs to their signature dishes and cooking times—and a grid to track logical deductions. Clues are provided in text form, requiring players to mark definite matches and exclusions systematically until the entire grid is solved. Its position in the market is clear: a no-frills, dedicated tool for a particular type of thinker, rather than a flashy game packed with mini-games. The core functionality revolves around the interactive logic grid. Tapping a cell toggles between three states: a checkmark for a confirmed match, an X for a confirmed exclusion, and a dot for notes or temporary marks. This simple input method is intuitive. Puzzles are categorized by difficulty, starting with small 3x3 grids and progressing to more complex 5x5 or 6x6 challenges. A key feature is the error-checking system, which prevents players from making contradictory marks, effectively guiding the learning process for newcomers. The app also includes a 'Hint' system that can reveal a random correct match, though using it typically requires watching a video advertisement. In terms of user experience, the interface is clean and focused, with minimal distractions during active puzzle-solving. The real-world use case is straightforward: it serves as a portable mental workout for commutes, waiting rooms, or winding down in the evening. The progression system provides a tangible sense of accomplishment. However, the experience is periodically interrupted by full-screen video ads, typically between puzzles. A one-time purchase is available to remove these ads, which is a critical consideration for heavy users. Some interface elements, like the clue list, can feel slightly cramped on smaller phone screens, but this is a minor quibble. User feedback, as seen in app store reviews, consistently praises the satisfying and engaging core puzzle loop. Many reviews express a genuine fondness for the game's mechanics. However, this positive sentiment is frequently tempered by complaints about the advertising implementation. Specific reports, like the one mentioning 'Food Match' ads becoming unresponsive and blocking gameplay, highlight a technical flaw that can severely degrade the experience. Another common thread is players exhausting the puzzle catalog and requesting more content, indicating high engagement from its core audience but also a potential limitation in long-term content supply. Overall, Logic Puzzles - Clue Game is a thoughtfully designed app that excels at its primary task. It provides a substantial library of well-crafted puzzles that successfully train logical deduction. The major caveat is its business model. For casual players, the ad interruptions may be tolerable, but dedicated enthusiasts will likely find the ad-free purchase essential. The app's value hinges entirely on a user's tolerance for advertisements and appetite for a very specific, repetitive, yet deeply satisfying type of puzzle.
