The Basics

Connect series of dots via a path (horizontal and vertical turns are allowed, diagonal turns not) to remove them. Connect a square or rectangle of dots to remove all dots of that color. A typical goals is to remove a certain number of dots from a specific color. There are a couple of bonus games, one of them finding specific items on a picture.

Difficulty

Difficulty does not seem to increase much and so far using the 2x2 squares to remove all dots of a color is a very powerful feature that helps reaching the goals of the various levels fast.

Variation

As you progress through levels new features are introduced giving this game a lot of variation.

Visually

Graphics are a bit simple.

Free vs Paid

Can purchase in game credits and boosters to help you clear levels.

Is It Any Good?

I give Two Dots 8 out of 10 stars. Nice concept, but everything around the connect the dots game is confusing.
