This will help you meet your colour quota, and possibly spark off a chain of square formations that you can get rid of.

What makes the squares - technically four dots connected in a square formation - so powerful is that when connected, they will clear all dots of the same colour. It’s about getting as many squares as possible. The aim of Two Dots may seem to be about clearing the board, but it’s not. You might have come across many connect-the-dots or connect-three games in the past, but this isn’t like those games. This is the first point because it’s the golden rule. Here are some pro tips for surviving - and maybe acing - Two Dots. With various stages of gruelling mind-busters, it’s bound to burn hours of your day, and is quite honestly the perfect game for travelling.

The sequel to Dots, the game’s objective is to meet level-specific quotas by clearing multi-coloured dots off a board a goal that is harder than it seems.

Two Dots - available on the App Store and Google Play - is probably one of the most popular puzzle games there is (barring the unbeatable Candy Crush).
