320 puzzles. Find your angle.

Free · Designed for iPad. Not verified for macOS.

Find a fresh way to see every angle. Explore 320 puzzles across four levels and build a collection of 32 geometric cards, one piece at a time. Find the missing angle hidden in each diagram. Angle Puzzle is a geometry puzzle game about combining the properties of shapes. Explore triangles, parallel lines, regular polygons, congruence, inscribed angles and tangents. A different view of the diagram can reveal the next step. 320 PUZZLES, FOUR LEVELS Start with simple angle relationships and work toward problems that combine several ideas. There are 76 puzzle structures, with questions you can select and solve at your own pace. HELP THAT MAKES THE REASONING CLEAR Use three stages of hints and illustrated answers and explanations. Draw notes directly on the diagram to record angles or sketch an extra line. The illustrated guide and geometry mini dictionary help you revisit useful properties. BUILD A SHAPE COLLECTION Each puzzle you clear for the first time gives you one collection piece. Ten pieces complete a card. Discover all 32 geometric cards as their artwork appears piece by piece. A CALM PLACE TO THINK There are no timers or lives. Save favorites, resume where you left off, and switch music or sound effects on or off. The interface, puzzles and explanations support nine languages. Contains ads. For an unsolved puzzle, watching one rewarded ad unlocks all of that puzzle's hints, answer and explanation. Ads require an internet connection. Progress is stored on your device; no account is required.
