All Arithmo puzzles use the basic mathematics functions: addition, subtraction, multiplication, and division; with or without the use of parentheses. Welcome to mathematical heaven!
It’s very easy to play, and catchy once you’ve begun. There are one to two different main concepts behind all Arithmo puzzles. One is to find 3 numbers on a grid, ranging from 1 to 12, so that they match some math equation. The other is to place numbers on a grid to create a special sequence of 3 “connected” numbers, which gives a result ranging from 13 to 24. Both of these use only the basic mathematics functions. All of this is much easier than it sounds!
That "math equation" we mentioned in the last paragraph, made from "3 connected numbers", is called Equa. Equa-X is a term we use which means "the equation that makes result X." For example, "Equa-17" is the equation of 3 numbers that are connected on the grid, which together can make 17 if you add, subtract, multiply, or divide them together in any order or combination.
|8x12:6 = 16||(Equa-16)|
|(8-5)x7 = 21||(Equa-21)|
|6x3+5 = 23||(Equa-23)|
There are three different ways of "connecting" numbers in every single Arithmo game. Remember that "connecting" in Arithmo games always means numbers that are adjacent to one another on the grid.
The first way is a "straight" connection, where numbers are connected horizontally (all in the same row, as shown in picture 1), or vertically (all in the same column, as shown in picture 2). The second way is an "L" shaped variant, where connected numbers are not all in same row or same column, but they create an "L" in the grid (as shown in picture 3).
The third way is the "triangle" connection, called Equa-T. This is when hexagons are being connected into a “T” shape (as shown in picture 4).

Grid size can vary from game to game, depending on different skill levels. The smallest grid size would be 2x2. The biggest would be 9x9.
Arithmo puzzles are so simple to play, it’s a wonder that they’re so addictive! Players compete against themselves, friends or the clock to score points and solve brainteasers.
