Cric Quadro is a unique feature offered by the 11Challengers fantasy cricket app. It allows users to participate in contests by selecting only four players – 1 Wicket-Keeper, 1 Batter, 1 All-Rounder, and 1 Bowler – instead of the usual eleven players required in most other fantasy cricket contests. This feature adds an exciting twist to the game and allows users to participate in more contests with a minimal budget.
