## Review summary

Overall, players find IQ and R to be a fun, engaging brain teaser with solid puzzles that make it good for spare time. But several recurring issues mar the experience: intrusive, frequent ads; gating mechanisms that force reviews to unlock answers or pass levels (notably level 54); occasional crashes or inability to open the app; privacy concerns over ad tracking; and requests for more variety or challenge. The strongest themes are ad fatigue, level-54 frustration, and occasional technical problems.
