Brain Out is a popular puzzle game known for its unconventional and often illogical questions. Level 81, asking players to 'Masukan Angka Terkecil' (Enter the Smallest Number), is a prime example. The trick isn't to simply enter the number 1. Instead, the solution lies in recognizing the layout of the number pad. The smallest number you can form using the existing digits is 0. This highlights the game's emphasis on creative problem-solving and thinking outside the box, rather than relying solely on conventional logic.
