During the game, as long as you click on two identical patterns within the time limit, if the connecting lines between the patterns do not turn more than 2 times and do not pass through other patterns, they can be eliminated. The clearance condition is to complete the elimination of all patterns. If the player's thoughts are temporarily blocked during the game, he can choose to press the prompt button or the break button at the top of the screen to get assistance from the computer. However, there are only three opportunities for each level, so you must grasp it carefully. In addition, there is a pause button, which can provide players with a temporary stop of the game, and there is no limit to the number of pauses. Note that all levels end after the tenth level and will return to the front level again. Of course, it is not easy to complete all the levels. The difficulty of the game will continue to increase in each level, so you must continue to work hard!
