Cards can be used as-is or fully customized with options such as grid size, color gradients, fonts, backgrounds, color themes, images, instructions, and free space settings. An ink-saver mode helps reduce background graphics for efficient printing. Users can also set the amount of empty space in each cell, ideal for writing in answers during play.

Once finalized, any number of cards can be downloaded in PDF format for printing or played directly online using a built-in online bingo caller and optional virtual cards. The caller also supports custom audio prompts to make activities more engaging.

A quiz mode lets users choose between showing the full equation (for example, a + b = c) or hiding it to display only the result. This offers flexibility for different skill levels or teaching approaches.

Additional topics, including subtraction, division, and math vocabulary, can also be created using their Free Bingo Card Generator.
