Triangle puzzle - as the name suggests - is a game about solving puzzles. The puzzles of different size consist of pieces made of small triangles. This pieces shall all be placed on the hexagon in the middle of the screen, leaving no space empty and no triangle sticking out. It's a simple principle, but as most people aren't quite familiar in dealing with triangles it's not always as easy as it seems.
Play Level Mode:
In the play-level-mode you can choose to solve puzzles with a side length of 2, 3 or 4. The levels are predefined, starting with easy levels consisting of few pieces. Whenever you solve a level, you unlock the next level - the farther you get, the more pieces the puzzles consist of, which leads to a rising difficulty.
Play Random Mode:
In the play-random-mode you can create your own, customized puzzles. You decide how big the puzzle shall be and how difficult it is to solve. You even have the option to create scattered puzzles where the triangles of one piece aren't connected, which makes it more easy (or more challenging?) to find a solution. The puzzle shown in the random menu is just an example of how the puzzle may look - but it's not the exact puzzle you later solve (they are created randomly every time you start a new game).
