Onet Connect Pro is a very simple game that can be played by anyone. The gameplay is based on classic board games, such as Onet. The objective of the game is to connect pairs of identical images in no more than three lines. If a pair is connected in more than three lines, then the images will not match. The difficulty of the game increases as the number of pictures in the board increases. There are five levels of difficulty. On each level, the number of images in the board will increase. On the other hand, the number of pictures that you can connect in a single line will decrease.
