Almost everyone knows how to play tic-tac-toe. Dotted tic-tac-toe is a multiplayer game to teach kids about number systems.
- Players throw a dice in turns.
- Each square in the board has the capacity of 9 dots.
- Players should put dots into one of the boxes as many as their dice shows.
- While putting down dots, players must be careful not to exceed the capacity of the box. In such situations they have to put dots to another box that has capacity.
- Whoever gets right to left, upside-down or diagonal three boxes will be the winner.
Beauty of this game is although it is competitive, it requires help of your opponent.
In the first three rounds players get 5, 6 and 3 from the dice:
Fourth dice is 1 which gives second player a chance to complete a box.
In the next four rounds players get 5, 5, 6 and 4 which gives again second player to complete another box.
Game resolves in the next rounds as shown in the following:
In this version of the game, use a coin instead of a dice.
- Consider that a box can have either of the following: A head & tail (tail & head is the same) or a tail & tail.
- A square can never had head & head, since 1+1=2 which is overload for the binary number system.
- This means that every box is either 1+0=0+1=1 or 0+0=0.
- So in this version of the game, x-o-x turns into 1-0-1. Right to left, upside-down or diagonal 1s or 0s wins the game.
Once again, although the game is competitive, you’ll need your opponent’s help.
First two coin tosses are both tails.
Then four consecutive heads are tossed.
Game resolved after three consecutive tails.
