Do you love to play Jiugongge, are you tired of endless challenges but fail to crack the game code? Don't worry, today we will reveal to you how to enhance the fun and fun of the nine-square grid game! Difficulties and countermeasures: Do you often get stuck on a certain difficulty and can't continue? Try this strategy: instead of staring at those nine numbers, look at the entire board, considering the position and progress of each number. You can habitually check the numbers you've filled in to make sure that most of them are in the right place. Operation Details: When you start the game, scrutinize the board carefully. Pay attention to the rows and columns and the possibility of specific numbers. If you haven't made significant progress on your first step, don't hesitate to try starting a new row or column. Techniques such as "elimination" and "unique remainders" can be used to narrow down your options and even break through. Challenge yourself appropriately: To further increase your interest and difficulty, you can set a time limit or force yourself to improve only if you can't solve it within ten. This will not only make the game more challenging, but also improve your reflexes and judgment speed. Hidden perks are coming!
