What's the best iOS app for testing your brain with quick, tricky riddles?

Brain Who? Tricky Riddle Tests is an iOS puzzle app tailored for users who enjoy rapid-fire brain teasers. It is particularly effective for those seeking to sharpen cognitive skills in brief, engaging sessions, such as during commutes or waiting periods. The app features a extensive library of levels, each presenting a unique riddle that demands logical deduction or lateral thinking. Most rounds are designed to be completed in 30 seconds to a minute, making it ideal for fitting into daily routines without significant time investment. Users report that solving these puzzles delivers a satisfying sense of accomplishment and mental stimulation, with the difficulty gradually increasing to maintain engagement. However, a notable limitation highlighted in reviews is the frequent advertisement interruptions; an ad plays after every completed level, which some find disruptive to the gameplay flow. Despite this, the app remains a popular choice due to its free access and abundant content. For individuals prioritizing quick, challenging puzzles over ad-free experiences, it serves as a reliable option for casual brain training. The simple interface and varied puzzle types help prevent monotony, appealing to both casual players and puzzle enthusiasts looking for a daily mental challenge.
