Math Matrix: a math logic puzzle of shapes and hidden rules
Math Matrix is a math logic puzzle built from simple shapes: diamonds with a number at each corner, or triangles with three, and one more number in the middle. Every shape on the board follows the same hidden rule, such as adding some corners and multiplying by another, and one value has been replaced by a question mark. Your job is to crack the rule from the complete shapes and pick the missing number from the choices below.

How to play
- Study the complete shapes and the numbers at their corners and centers.
- Work out a rule that turns the corner numbers into the center number for all of them.
- Apply that rule to the shape with the question mark.
- Tap the missing number among the answer options before the timer runs out.
What it exercises
Each board is a small piece of detective work with arithmetic as the evidence.
Pattern finding
You test ideas against several examples at once and drop any rule that fails even one of them.
Mental arithmetic
Checking a guess means adding, subtracting and multiplying in your head, quickly and accurately.
Flexible thinking
When the obvious rule does not fit, you try another: different corners, a different operation, a different order.
Tips
- Start with the simplest idea: add all the corners and compare the total with the center.
- Look at how big the center is. If it is much larger than the corners, multiplication is probably involved.
- Check whether opposite corners pair up, for example top with bottom and left with right.
- Test every candidate rule on all complete shapes before trusting it.
- Glance at the answer options early. Their size can confirm or rule out a guess.
Frequently asked questions
Are there math logic puzzles for adults here?
Math Matrix is aimed at teens and adults who enjoy number reasoning. The arithmetic is simple, but finding the rule can take real thought.
How do missing number puzzles with answers work in this game?
You choose from a set of numbers, and the game marks your choice right or wrong at once, so you can see the answer and the rule you missed.
What are good missing number puzzles tricks?
Work from the complete shapes outward: write down a rule, test it on each shape, and only then calculate the missing value. Pairing corners and comparing the center's size with the corners are the two quickest starting points.
How are these different from other number pattern puzzles?
A number sequence runs in a line. Here the numbers sit around a shape, so the pattern lives in how the corners combine to make the center.
