2. Range Game, select a range between one and hundred then, a random number is generated between 1 and 100;

• If the random number doesn't falls in the given range, you lose everything.

There is use of probability in every move suchh that bot sometime make mistakes and there is randomness in the game.

• If bot wins in next move, then only 90% of the time the bot plays the winning move,
• If user is going to win on next move, bot blocks it 75% of the time,
• Bot tries to go with center piece only 20% of the time,
• Similarly, corner pieces are favored 30% of the time.

This also prevents high draws and let user win occasionally.
