      @tancg3015 3 года назад +1

      There's a bit more to it then starting either in the middle or a corner. Start from the side to stump someone who thinks they got the basics figured out. Mathematically, the odds of winning are smaller but psychologically this works better against more experienced players. This line of play is covered in the wiki page but not the one way you could end up in a winning "fork" position when you do not go first. It requires your opponent to make a mistake that only veteran players tend to make. Tic-tac-toe is figured out for sure, just not quite in the way most people say it is, which goes for much else in life too. Have fun working it out!

    One of the first things I ever coded (that wasn't a part of my course on how to code) was a bot that plays Tic Tac Toe against you and will always win or end in a draw if you're smart enough to counter it. It took a couple days to code it all, but I was really happy with the result considering that I wasn't following anyone else's instructions and figuring it out all on my own. Coding that bot has permanently burned Tic Tac Toe gameplay strategy into my brain.

    basically, if you go first, go in a corner, and there are 2 continuations:
    -if they move on ANY edge, play in the center
    -otherwise, try playing in the opposite corner, otherwise just play in a random corner.
    And then continue by playing "naively": win if you can, avoid losing.

    I figured out the tik tak toe 'never lose' strategy independently 20 years ago.
    Also you can have a never lose scenario from starting at the middle point. And if you play against an opponent who knows these strategies and always plays first, you can draw all the games no matter which moves he takes.
    This is probably why there is no tik tak toe championships anywhere.
    All games will lead to a tie😂

I coded the computer to play, and then had my brother play against it. I analyzed every game and then tweaked the algorithm that selected the computer's move. Eventually I figured out these principles, and I had programmed a Tic Tac Toe-playing computer that was unbeatable. Consequently I also became unbeatable at Tic Tac Toe.

    My variant on the game that I want to share with the world is 3 handed Tic Tac Toe. Three symbols: 0, X ,and Y, and on a 4x4 (rather than 3x3) grid, but you still aim to be the first to get your symbol in a line of just three. I tried it out and it works quite well. You don't always need to block off an opponent's line, you can leave your other opponent faced with the immediate need to do that, and branch off on your own. Maybe it models international conflicts.

    There's a simple game I sometimes use to annoy people. You start with three piles of matches: with 3, 5, and 7 matches. Players can take as many matches as they want per turn from any pile, but only from one pile per turn. The objective of the game is to make the other player take the last match. If you know the winning combinations, you can always force a win whenever you go first (and whenever the opponent goes first but makes a mistake along the way). It doesn't even matter which pile you take from first; as long as you take only one match from any pile you can always force a win.

    I was in the Philippians with my dad and brother. I was 10 at the time. Dad and my brother were off doing something and for whatever reason I don't remember, I was left to play by myself. Then a little girl about my age was dumped in the same situation. She didn't speak English but I managed to mime well enough to teach her tic tac toe which we played in the dirt with a stick. I won exactly one game before she figured out the pattern. The best I could do was a draw from that point on. Never saw her again but man was she good at that game.

    @ 1:10 you actually can win already in two moves as X.
    Let's call the grid 1-9, with 1 being in the top left and 9 being the bottom right. Middle is 5.
    You start in square 7, they pick square 1. You pick square 3. You win. Why?
    If they move to block you, you pick square 9, which lets you win two different ways instead.
    So you can literally win in two moves, though technically it's four. This is basically the same example you show at 1:30, but slightly different in that O picks the top corner instead of center first.
    P.S.
    If Tic Tac Toe was a competitive game like Chess; I'd probably be close to a grand master. I can beat Ultimate Tic Tac Toe on Impossible difficulty... sometimes.

  • @alexolivers9476

    I actually found out how to never lose tic tac toe by myself. I've also done this for a 2 player version of the game ten, but that one was so easy that everyone in my second grade class figured that out. That game guarantees that the first player can always force a win. (obviously you have to play the right way, but if you do, there is no way to lose or tie.)

  • @Stratelier
    @Stratelier 3 года назад

    Nim could have also made a good example -- e.g. if you have a pile of 5 sticks and each player can take 1 or 2, then the first player can always win (and this works regardless of whether taking the last stick is counted as a win or loss).

  • @calebklingsheim947
    @calebklingsheim947 3 года назад

    On a whim, I decided to investigate the idea of 3D tic-tac-toe where the rules are that the board becomes a 3x3x3 cube (therefore 9 standard boards; three lengthwise, three heightwise, three depthwise) and to win you simply have to get one three in a row (normal tic-tac-toe win condition). While it might seem substantially more complicated and interesting than regular tic-tac-toe, there's actually a guaranteed way for the first player to win. They simply pick any corner; when the other player plays a move, the first player picks a space that:
    1) Is adjacent to the first space player 1 picked, and
    2) Is on a board in the cube that player 2's chosen space does not appear on
    Therefore player 1 effectively gets 2 moves on a standard tic-tac-toe board before player 2 can make 1 on the same board, making it a guaranteed victory using a similar method to the one described in the video. There are other spaces player 1 can pick on their second turn to guarantee the win (for example, using the opposite-corner method described in this video), but this strategy seemed most intuitive at first.
    I was kinda disappointed that the end result is that the winner is decided by a coin flip, but at least it is trivially more interesting than standard tic-tac-toe since there will always be an uncertainty of who will win.

    Minimax may not be able to _solve_ complex games, but that doesn't mean it's not feasible - you don't have to solve a game to virtually guarantee a win. The computational power available still allows the calculation of a substantial number of potential moves ahead (look ahead), and the decision trees can be quickly pruned based on various techniques such as fuzzy logic, lookup tables, or historical analysis. An algorithm that can minimax seven turns ahead will beat most human opponents.
