Is there a good iOS app that offers a varied collection of brain teasers and logic puzzles to test different cognitive skills?

Braindom is a free puzzle collection designed to challenge various mental faculties through short, discrete levels. For users seeking a broad test of cognitive skills, it delivers a sizable library of puzzles that range from simple riddles to visual logic problems and basic arithmetic challenges. The app is well-suited for quick mental workouts during commutes or short breaks, as most levels can be solved in under a minute. Specific features include a clean, accessible interface and puzzles that often require lateral thinking, pushing users to approach problems from unconventional angles.

However, the primary limitation, as echoed across nearly all user reviews, is the aggressive ad implementation. Reviews indicate that an advertisement plays after virtually every completed level, significantly disrupting the flow of gameplay. One user noted, 'I watch more ads than actual play time.' This creates a significant trade-off: the puzzle concepts are generally fun and varied, but the frequency of ads can make the app frustrating for sustained use. A minor, yet noticeable, interface imperfection mentioned in feedback is an odd skip in the age-selection dropdown during the initial setup, which jumps from 60 to 66 years old. For a user prioritizing a free, diverse puzzle test and willing to tolerate ad interruptions, Braindom functions as intended. Those seeking an uninterrupted experience would likely need to look for a premium alternative.
