Math Triangles: Number Puzzle

Math Triangles is a number puzzle on a big triangle made of small ▲ and ▽ cells. A few numbers are given. Each ▲ is made from the two ▲ just below it, and each ▽ from the two ▲ beside it. Find the missing numbers and fill the whole triangle.

HOW IT WORKS
• The first world is the classic number pyramid: 3 and 5 make 8.
• Each next world brings its own rules: the difference between two numbers, multiplying, and a triangle that subtracts on the way up.
• Every puzzle has exactly one answer, and logic always gets you there. You never have to guess.

5 WORLDS, 150 LEVELS
• Pyramid: each ▲ adds the two below it
• Difference: add up, subtract across
• Big Triangle: bigger triangles, longer chains
• Times: multiply up, add across
• Upside Down: subtract up, add across
Each world has 30 levels, from a few blanks to almost empty boards. Earn up to 3 stars per level and open the next world.

HINTS THAT TEACH
Stuck? A hint fills in one number and shows why: the rule in words, the equation and the cells involved, outlined on the board.
‎17 = ? + 8 → ? = 17 − 8 = 9‎
You learn the step, not just the answer.
