It's simple. I played games with my dad and lost. I don't believe it. I have been here several times. I lost and won. Is there any pattern? I noticed that as long as I grab the number 26 first every time, I will definitely win. Because if I grab the number 26 first until the number 30 has four digits, according to the rules of the game, the maximum number of digits reported each time is three, and the minimum number is 1, then when my father reports 1 digit "27", I will report three digits "28, 29, 30", and I will grab the number 30 first; Dad reported two numbers "27, 28" and I reported two numbers "29, 30", so I can grab 30 first; When dad reported three numbers "27, 28, 29", I reported a number "30" and won. It seems that the number of 26 is definitely a guarantee of victory. So, besides grabbing the number 26? In the previous round, what figures must I determine to ensure my victory? According to the method of grabbing the number 26 first, I made a calculation: to win, we must remember these numbers firmly in each round, which are 22, 18, 14, 10, 6, 2 respectively. So, is this the rule in this game?
I found the pattern, and I played with my dad again. My dad goes first 1, 2. I think my dad robbed it, so I'm a little anxious. I said 3, 4, dad said 5, 6, and dad robbed 6 again! I said 7, 8 and 9, and my dad reported 10, 1 1, 12. I quickly reported 13, 14, and I was secretly happy. Finally got 10! ! Then, my father reported three numbers, and I reported 1 number; Dad reported two numbers, and I reported two numbers; Dad reported 1 number, and I reported 3 numbers. I won! Dad was not convinced and played a few more games, but I mastered the rules and won. Dad asked, "What a coincidence?" I smiled and said, "It's not an accident, it's a coincidence. I found a rule! " Dad also smiled: "In fact, I also know that you are really smart." "Then, my father said the law again. This sly dad! It bothers me not to tell me!
There are so many math rules in the game! We can find them as long as we use our brains more.
