Brain Test All-Star: IQ Boost represents the latest installment in Unico Studio's long-running puzzle franchise, positioning itself as a culmination of years of development experience in the brain teaser genre. The Android application builds upon the established formula that has made the series popular, offering a fresh collection of puzzles while introducing new mechanics aimed at quantifying cognitive improvement. The application features over 100 new levels that employ the signature deceptive puzzle design the series is known for, requiring players to think beyond conventional solutions. The standout addition is the IQ scoring system, which tracks performance across various cognitive domains including logical reasoning, pattern recognition, and creative problem-solving. Each puzzle is designed to challenge different aspects of cognitive function, with the scoring system providing measurable feedback on improvement over time. The game maintains the series' trademark approach where solutions often involve unconventional interactions with the game elements. User experience is characterized by minimalist interface design with intuitive touch controls, though some performance issues have been noted. The game follows a progressive difficulty curve, starting with accessible puzzles that gradually introduce more complex challenges. Real-world usage patterns show players typically engage in short sessions, making it suitable for casual play during breaks or commute times. The ad-supported model presents frequent interruptions between levels, which has been a point of contention among users despite the free-to-play accessibility. User feedback indicates generally positive reception with consistent praise for puzzle design, though technical performance and advertising frequency emerge as common concerns. Multiple reviews from Vyshak Kalliyil on August 31, 2025, note that while the game provides enjoyable deception-based puzzles that balance challenge and accessibility, performance lag and ad frequency detract from the experience. These reviews specifically mention that puzzles are 'hard but always easy' once the solution is understood, highlighting the satisfying 'aha moment' characteristic of the genre. The application succeeds in delivering engaging cognitive challenges with measurable progression tracking, making it particularly valuable for users seeking mental stimulation. However, the experience is compromised by technical performance issues and aggressive advertising implementation. Ideal for puzzle enthusiasts who appreciate lateral thinking challenges and can tolerate the free-to-play model's limitations, Brain Test All-Star: IQ Boost offers substantial content despite its technical shortcomings.
