Bermuda Triangles
A super challenging number game. This is like an extreme version of Sudoku, only involving triangles. It’s difficult to explain, but basically you need to get all the numbers on the inside of the nine triangles and the outside of the triangle to include the numbers one through nine without repeating any numbers. Each puzzle has several solutions though. This is a challenging numerical strategy game that is designed for one player, but if you need to ask for help, by all means do so! There are three difficulty settings: easy, medium and hard.
