About game
How big is a familiar object compared with an animal, a building or a landmark? Put your sense of scale to the test. In each round, the blue silhouette is your reference and you set the size of the red one. Compare them by eye, submit your guess and see how close you were. Each level has five rounds and up to 500 points to earn for accuracy. Play three modes: Classic gives you a new pair each round; in Ladder, the previous target becomes your next reference; and in Reference, the same guide stays in place for the whole level. Unlock levels and beat your best score.
How to play
Choose a mode and press “Play”. In each round, the blue silhouette is the reference at its correct size. Resize the red silhouette by dragging the handle with a mouse or finger; on a phone, you can also pinch with two fingers. Use the measurement shown—height, length, width or diameter—to judge the ratio. When it looks right, press “Check”. You will see the correct size and earn points based on your accuracy. Complete five rounds to finish the level and unlock the next one.
