The first think is that bingo is classed as a game of chance.
In 75 ball bingo, you have a chance of 1 in 75 of getting a ball when the bingo game starts.
In my opinion the only strategy that exist when you play bingo is that you most looking at the probabilities that one number will appear over another.
When you play bingo online of the 75 ball variety, your bingo cards or tickets have a random selection of 25 numbers.
One think is that in 75 ball bingo there are 7 balls that end in the number 8. If 8 is on your bingo card, then there are 6 bingo balls left that will end in 8. This means your chance of getting another 8 is lower than for other numbers.
Also you most pay attention when you select your cards, you can increase your winning chances.
Then I wish you Good Luck.
