The nine-square grid number skills are revealed!
The nine-square grid, for many people, may just be an ordinary game. However, the mathematical skills contained in it are amazing! With reasonable number arrangements, you can easily challenge difficult levels. Next, we will introduce you to some nine-square grid number tricks.
Basic steps: Understand the rules of the game
If you want to play the nine-square grid, you first need to understand the basic rules. In a 3x3 grid, you need to put the nine numbers 1 to 9 in turn, and the numbers on each horizontal, vertical and diagonal line add up to 15.
Observation first: break through from the edge
The key to solving the nine-square grid is to first observe a few important clues. For example, you can choose two adjacent number positions to crack. Each determined number can give you clues to other numbers. From here, gradually penetrate the overall situation and discover more laws from it.
Number pairing: subtraction option
You can use the number pair method to reduce duplication of work in unselected locations. For example, the position of the number 1 is actually unique next to a known number in the row. Once you find two locations, decide decisively on one of them. Then use the counter-evidence method to check whether the other position is correct, so as to reduce invalid attempts.
Backward method: step by step inspection
If you are stuck, you can use the backward method. Step by step, revisit the numbers you have filled in before, look for possible mistakes and correct them. Always check whether the numbers that are already in the determined position affect other positions, and count the non-electoral areas after elimination before making different voting matches.
