## What is Area Puzzle by TKPY?

How large is the blue area?

One rule runs through every puzzle: look at the diagram and find the area shaded blue. Split a shape, move a part or fill a gap. A different perspective can reveal a path to the answer.

400 puzzles at your own pace
Choose from Easy, Normal and Hard. Start with any available puzzle, whether you have a short break or time to think it through.

See each idea step by step
Three hints and illustrated explanations help you explore the solution. Move forward and back yourself to revisit the parts you want to understand.

Sketch, star and revisit
Try your ideas with a pen, eraser, undo and clear. Star the puzzles you want to return to and find them again in Favorites.

Turn solutions into geometric art
Your first correct answer to each puzzle earns one piece. Ten pieces complete one artwork, with 40 artworks to collect. Each artwork's name stays a surprise until it is complete.

Available in Japanese, English, Simplified and Traditional Chinese, Korean, Spanish, Brazilian Portuguese, French and German. Progress, notes and favorites are saved on your device.

About ads
The app includes banner ads and ads at natural breaks, such as leaving a puzzle. Earn the reward from one video ad to unlock all hints, the answer and explanations for that puzzle. You do not need to watch again for the same puzzle.
