IQ Test - IQ Arena is a pure mobile puzzle and brain-training game developed by Neorem. It's available for free on both the Google Play Store for Android devices and the App Store for iOS. As a mobile-exclusive title, you won't find it on PC platforms like Steam or on consoles like Xbox or Switch. The game launched a while back and has garnered a solid number of installs on Google Play, indicating a healthy player base. The core download and gameplay are completely free, which is great for anyone wanting to give their brain a workout without spending a dime. However, like many free-to-play mobile games, it does include in-app purchases. These typically range from a couple of dollars to remove ads or unlock certain premium question packs, up to around $10 for larger bundles that offer extensive content or permanent ad removal. You'll also encounter occasional video ads, usually after completing a test or to earn hints, but they're generally not overly intrusive.

Playing IQ Test - IQ Arena is straightforward: you dive into a series of timed puzzles and logic questions designed to challenge different aspects of your intelligence, like pattern recognition, spatial reasoning, and verbal logic. The best part, in my opinion, is the 'Arena' mode itself, where you can compete in real-time against other players from around the world. There's a genuine thrill in racing against the clock and another person to solve a puzzle correctly. My favorite part is the sheer variety of question types. Unlike some brain games that get repetitive, this app throws numerical sequences, visual analogies, and word problems at you, keeping each session fresh and engaging. It feels less like a sterile exam and more like a dynamic, competitive puzzle battleground.

Compared to other popular brain-training apps like Peak or Lumosity, IQ Arena stands out for its direct, competitive focus. While those other games often focus on personalized daily workouts and tracking long-term progress, IQ Arena is all about the immediate, head-to-head challenge. It's less about a curated cognitive science program and more about raw, fast-paced problem-solving under pressure. If you enjoy the social, competitive aspect of trivia games but wish it was more about logic than general knowledge, this is the perfect app for you. I'd recommend it over more solitary puzzle collections because the live multiplayer Arena adds a layer of excitement and replayability that solo play just can't match. It turns brain training into a genuinely fun and adrenaline-pumping game.

• Live Multiplayer Arenas 🎯: The core feature that sets it apart. You're matched in real-time against another player to solve the same puzzle fastest, adding a thrilling competitive edge you won't find in solo-focused apps like Brain Test.
• Massive & Varied Question Bank 🧩: The game boasts a huge library of puzzles spanning numerical, logical, spatial, and verbal domains. This variety prevents monotony and tests a broader range of cognitive skills compared to more niche puzzle games.
• Global Leaderboards & Leagues 🏆: Beyond one-off matches, you can climb seasonal leaderboards and compete in leagues. This long-term progression system gives you goals to strive for, similar to ranked modes in other competitive games but applied to IQ testing.
• Quick-Fire Game Modes ⚡: Alongside the Arena, modes like survival or speed tests offer different ways to play. These bite-sized sessions are perfect for a quick mental warm-up during a break, making it super accessible on your Android or iOS device.

• Genuinely Competitive & Engaging 🏁: The real-time PvP is a game-changer. It forces you to think quickly and accurately under pressure, which is far more engaging and rewarding than simply ticking off solo puzzles in an app like Elevate.
• Excellent for Short Sessions 📱: The game is perfectly designed for mobile. You can install it, jump into a couple of Arena matches in under five minutes, and feel like you've had a substantive and fun brain workout, which is ideal for gaming on the go.
• Free Core Experience is Robust 💰: You can download and enjoy the vast majority of the game's content without spending a cent. The free model is generous compared to some competitors that lock core features behind paywalls early on.

• Ad Frequency Can Disrupt Flow 📺: While not the worst, the ad breaks (especially video ads) after every few tests can interrupt your session's rhythm. It's a common mobile game trade-off, but it feels more noticeable here when you're in a competitive mindset.
• Some Question Explanations Are Lacking 🤔: After getting an answer wrong, the explanation is sometimes too brief or unclear. Games like 'Brain It On!' often do a better job of teaching the logic behind the solution, which is a missed learning opportunity here.
• Matchmaking Can Be Uneven ⚖️: Occasionally, you might get matched with a player whose skill level seems vastly different, leading to one-sided matches. This isn't as polished as the ELO-based matchmaking you'd find in dedicated competitive esports titles.
