Dire Straits

Become the sultan of math

Object of the Game

To find all proven three-straight-connected numbers in a grid each of whose sum will equal one of the demanded Equas.

How to Play

  • Choose a prefilled number grid.
  • For this game numbers are connected in straight threes vertically or horizontally only, as shown in the diagrams below. No “L” shape is allowed.

Horizontal equa
Vertical equa

  • Numbers can be calculated in any combination, but keep in mind the mathematical order of operations as you calculate:
    • First perform any calculations inside parentheses, if they exist.
    • Next perform all multiplications and divisions
    • Lastly, perform all additions and subtractions
  • Found straits cannot cross each other. Each number can only be used in one strait.

Example

Find 6 straits of Equas 14, 16, 17, 18, 19 and 22 in this 5×4 grid. The solution is as follows:

Let’s check the solution:
2 x 11 – 3 = 19
4 + 6 + 4 = 14
8 x (10 – 8) = 16
3 x 7 + 1 = 22
11 + 8 – 1 = 18
3 x 7 – 4 = 17
