The game itself is fun, but sooooo many ads, and you do not actually win any money. It is the same as all the other win free money  games, you need to have a certain amount before you can cash out, and any cash rewards  earned are given in 0.00001 of a cent.

Bingo Cash is a legitimate gaming app that offers a fun experience that offers real money prizes in cash games. It provides free practice rounds and has an engaging community. However, it has limited earning potential, and you may need to stake your own money to play.

Randomly chosen numbers, usually up to 75 or 90, are called out by a banker.  The first player to achieve a card (or a line) in which all of the numbers have been called shouts bingo  or house  and collects the entire stake money, usually less a specified percentage, if that is permitted by local law.

Up to 15 players are randomly issued a number from 1 to 15 which corresponds with the top row of the bingo flashboard. Numbers are then drawn and the first person to have all five numbers in their column be drawn wins.
