Kangwon World Builder

Eight buildings flash across a dark purple screen, one by one, and your only job is to remember the exact order they appeared in. It sounds simple until the speed picks up, the sequence stretches to five or six buildings, and your brain starts second-guessing itself on the third tap. Kangwon World Builder trains visual memory in short, sharp rounds that get harder before you even notice the difficulty creeping in. Most people think they will remember. Most people are wrong.
