Charm is sometimes hard to find in games, but TwoDots pulls it off. With a minimalist play style, it’s both challenging – and inviting.

It’s a matching puzzle, that requires you to connect like-colored dots. Just beware that as the difficulty ramps up and you start losing, you’ll have to either pay to keep playing or walk away for a while so your lives can regenerate.
