The goal of this game is to count all triangles for each given graph. Some triangles can be formed from the union of smaller shapes. There are 100 puzzles ranging from easy to intermediate difficulty. Be aware, some of the puzzles can be frustrating and take several minutes to solve. Solutions are offered, but they have to be consulted as a last resort. The game requires several abilities from your part, including good memory, visualisation skills, abstract way of thinking, ability to concentrate, self-discipline, and patience. The game can appeal to people who enjoy puzzles, brain teasers, IQ tests, logic problems, cryptic crosswords, geometry or math. If there is interest, more levels can be added in the future.
