Kolkata Fatafat (Kolkata FF) is a popular number-guessing game played mainly in Kolkata and across West Bengal. Players choose a number and place a bet, and the results are announced several times a day. If the selected number matches the result, the player wins money; otherwise, the bet is lost. Many websites publish daily results and old charts for players to check previous outcomes. The game is similar to Satta Matka and mainly depends on luck.
