Circle Pong by Super Droid Studio - Android App Featured
Simplicity has its virtues and among the hundreds of thousands of games on google plus there exist a huge selection of complicated games, with complex rules, dozens of units and untold rules, all creating games that are better played on tablets and require quite a lot of time, both to understand how to play and to play each session.
Of course, even among the games that are shorter and simpler by nature there exist a great variety. Some are puzzles which require puzzle and riddle solving, obviously. Others are arcades, designed to let the player struggle with difficulties while he or she fights to move the game's character from start to finish.
Finally, there exists the arcade or action genre which is simple and requires great hand to eye coordination, lightning fast reflex and unwavering concentration. These games are very popular because they are really great to pass a few idle minutes, are very relaxing as the player's fingers flash across the screen and the concentration needed helps the player focus easier on his tasks later on.
Circle Pong is a very interesting example of the action genre.
To sum things up, Circle Pong is both simple, eminently playable and a lot of instant fun, great for any idle moment and great for both reflexes and concentration.
