Game Levels 4 Tic Tac Toe (Single Player)

Single Player Game

In single player game you may provide at least three levels, like EASY, MEDIUM and HARD.
 
You know it's a two player game so when the user will select to play with Single Player then the opponent player will be system(like Phone or PC).
So in this game when the player will moves his turn, system will move the turn automatically. No we have to decide that how to instruct the system to move its turn on which blank pad, Now I am going to briefly describe about the instruction for the computer/phone/any system.
 
Label: EASY

In this level you may instruct the system to move its turn randomly on blank pad.
What You should keep in mind at this level:

STEP 1

Count all blank PAD(which is not marked by any player(either by player or phone) and put all blank pads name into:

List<string>

Note: Where pad is a button control. 
[WHERE : PAD denotes all nine boxes on which user marks their move either by O or X ] 
Example

List<string> allBlankPad =new List<string>()

Now put all the blank pad's name into this List of string (allBlankPad) 
STEP 2

Generate random number from 0 to Count(total no of blank pad -1)
 int buttons = randomPad.Next(0, allBlankPad.Count - 1);
STEP 3

Mark the pad at: allBlankPad[buttons]
Here buttons is the random index  of blank pad

Example Code

   
int buttons = randomPad.Next(0, allBlankPad.Count - 1);
string haveToMarkAsMobilePad = allBlankPad[buttons].ToString();

Label: MEDIUM
Label
STEP 1

Find the allBlankPad, allPlayerMarkedPad and SystemMarkedPad and keep them into List<string> or ArrayList

STEP 2

Check all the win condition for opponent , If opponent has two consecutive marked pad then marked the pad to prevent them to won otherwise generate a random number from 0 to total number of blankpad+1 and mark the blank pad which suggested by random number.
You may use the following logic to do it.

Example Code
  1. public string Medium(List<string> playerAllMarkedPad, List<string> allMobileMarkedPad, List<string> allBlankPad)  
  2. {  
  3.       countPad = playerAllMarkedPad.Count;

Lable: HARD

In hard level do the steps of MEDIUM Level but when the opponent has no two consecutive marked pad then think on you move by which the phone could win and if any now possibility to win the make move which could help to win on next turn

Note:  Most of  the code will be same as  level MEDIUM except the random move because in medium level we are checking the win condition of opponent , if it is then we were marking those pad by which opponent could not win on next turn other wise we were marking any blank pad using random selection of blank pad.

But in this level we won't marked  any pad randomly. If opponent has no chance to win at next turn then phone will think about its win condition, if any possibility available to win then marked that pad to become winner or try to marked that pad which will help you to win at future turn.
Thanks!
