One Brain is inspired by the Stroop effect, a famous psychological test that measures how well you handle conflicting information. For example, it's harder to name the color of a word when the word itself spells a different color. This game challenges your whole brain as you fight to process the mixed signals and make the right call before time runs out. Game modes: • Colors: Does the word match the color it's written in? • Arrows: Is the arrow actually pointing the way it says it is? • Numbers: Is the math equation true or false? • Words: Which word matches the definition? How high can you score under pressure?

Do you enjoy trivia? Do you like playing a quick game or two before bed (or after bed, or any time in between!)? City Sort is a great game to give you a trivia fix and a little education at the same time! — Great! But how does it work? — You’re presented with 4 cities from your own country or around the world (you choose!). You then geographically arrange them by grabbing the icon on the right side of the card and sliding them up and down according to one of the following 5 categories: • Latitude • Longitude • Elevation • Population • Average Temperature (US only) The app will automatically detect which country you live in and present you with cities from that country. You can also pick the minimum population, which also sets the difficulty level: the lower the population minimum, the more obscure the cities get and the harder the game becomes. You also have the option of “Common US Cities,” in which case “interesting” cities within the US will be picked for you. For example, Kitty Hawk, North Carolina isn't very big, but something big happened there once upon a time!

Verdict
The clearest difference is in-app purchases: City Sort at none against One Brain's 1. City Sort also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
