Dots hits all the right notes. It's easy to pick up, hard to put down, and requires no explanation. It brings back memories of competing with classroom friends, drawing a grid of dots on a loose leaf sheet of paper and taking turns connecting them to see who could amass the largest number of connections. This mobile adaptation adds a single player mode without stripping out the multiplayer aspect, the fun, or the addiction. It has already acquired over 5 million downloads since its release on iOS two months ago, and now it's making its Android debut on both Google Play and the Amazon App Store.
It should come as no surprise that there isn't much to dots. Just swipe to connect two or more dots with a single line without using diagonals. The games tasks players with connecting as many dots as they can within the span of sixty seconds or scoring as many points as possible within the span of 30 moves. Both modes ensure that the game is always great for a quickie during the many lulls throughout the day.
Dots is the kind of game that was made for mobile, and it's available for free. Sure, there's an in-game currency also called "dots" that can be spent to get special powers, and you can spend real money to acquire more of them, but these IAPs are unnecessary and far from intrusive. Don't let their presence stop you from giving this a go.
