1.Randomly select one person to be the ”one”. The rest of the class becomes the “mob”.
2.Play begins by the “one” being asked a question. The player and the mob answer using their color coded cards displayed at the same time. Give a time limit to answer— like 15 seconds.
3.If the “one” answers the question correctly, any “mob” players that also answered correctly remain in the game. The wrong answered players are eliminated.
4.The next question and each succeeding question increases in difficulty. After correctly answering the first three questions, the “one” may choose to leave the game with their acquired points only before answering the next question. If they choose to go on and cannot answer the question then the “mob” wins.
5.If “one” answers incorrectly, his turn is finished and the “mob” (whoever is left) wins.
6.Points are awarded from low (for the easier questions) to high (for the harder ones.) The “one” accumulates points as he/she answers correctly. Whatever points have been accumulated when the “one” answers the question incorrectly are split between the remaining “mob” members or awarded to each mob member equally. The “one” receives no points.
7.Play ends when the “one” has eliminated the “mob” and receives all the points.
