The two ghosts, Vandana and Jayshri, spent Diwali in the bottles as they could not solve the previous puzzle (Revenge is Sweeeeeet). One evening while Ketaki & Roshni continued their preparation for CAT, the lights went off as usual. A bolt of lightning hit the table at the centre of the room and a bat appeared on the table. The bat circled the room once and transfigured into a ferocious-looking woman! She introduced herself as Joyce - The Ghost of CAT Future. She gave the 2 bottles one disdainful look and snapped her fingers. On the table, popped a board with six coins on it representing an ongoing game and two empty glass bottles akin to the ones in which Jayshri and Vandana lay trapped.
Said Joyce, "You two are mighty proud after trapping my sisters, aren't you? Why don't you pick on someone your own size. On this table is a game of Tic-Tac-Toe in progress. It was being played by my sisters before you two trapped them. Vandana played the orange play pieces while Jayshri played the green ones. Now tell me, had this game continued, who would've won? If you cannot answer my question, you two will be cursed into spending the next one year inside these two empty bottles just like how you've made my poor sisters suffer. And, yeah, you guys can wave a nice goodbye to CAT 2009."
"By the way, in case you don't remember the rules of the game, let's refresh your memory:
It's each player for himself/herself. If a player manages to place three of his/her pieces in a straight line (horizontal, vertical or diagonal), he/she wins.
If he/she cannot do so during the current turn, the player tries to thwart his/her opponent's victory by placing his own play piece in a row containing two of the opponent's play pieces."
"Thought you were too smart for CAT, huh? Let's see how smart you two really are!"
