'Nunca Cuatro', or 'Never Four', is an engaging online game featured by La Nacion that challenges players to fill empty squares with either a circle or a cross. The primary goal is to avoid creating a lineup of four identical symbols that are aligned in any direction — be it horizontally in a row, vertically in a column, or diagonally. This unique twist adds a strategic layer to a standard puzzle game, making it appealing for both casual gamers and puzzle enthusiasts.
