It's rare that you find a multiplayer split-screen game for Android phones. That's why I was truly excited to see one shoot up into the list of top purchases in the Android Market. 4 Player Reactor is a game that can be a ton of fun to play with a friend or a group.
The premise of the game is very simple: It will ask you to solve some sort of a puzzle and you must be the fastest person to tap in. The questions range from identifying shapes to simple math equations. Each question requires the players to concentrate on the center of the screen and judges their reaction time.
The graphics in the app are not really anything to write home about, but the puzzles it offers easily make up for that. Depending on what type of phone you have, this app will work well in a group setting, but for the most part, I just see this app being an awesome time-killer between two friends.
Overall, it's a great idea and really works well on the phone. I really wish there were more games like this for Android but for now, this one will be sticking around on my phone for a while. Check it out.
