Trigons

April 4, 2015

Are you ready for a SERIOUS puzzle challenge? 🙂

These puzzles have been around for a while and they somewhat resemble Tridoku, both in their appearance and in their name. However, trigons are completely different.

These puzzles with lots of triangles are called Trigons and they are not Sudoku. Sometimes they are also referred to as Trianglons. They have something in common with Killer Sudoku, because you are dealing with sums of numbers.

The rules of Trigons are:

1. Use digits 0 to 6 to solve the puzzle.
2. The numbers given in the puzzle represent the sum of the three digits on the side of the corresponding triangle.
3. Your objective of course is to match those sums.
4. Numbers CAN BE repeated in one triangle.
5. Each sum combination MUST BE USED ONCE and not more than once. All triangle sum combinations are given below the grid so when you use one, cross it off.

I will soon start posting tips on how to solve trigons. Basically, start with the 0 and the 18 and then analyze which sum combination can go where depending on the neighboring sums.
DO NOT GUESS! Look for two adjacent sums which differ by a large number – the possibilities are usually very limited. And don’t guess, please! 🙂

Trigons come in different shapes and sizes and if you have a particular shape which you prefer, please let me know.
