How does the game Multiplication table shooting work?

The Multiplication table shooting game allows you to practice the tables from 1 to 10. In the beginning, you choose one or more tables you want to practice. Then you enter the forest where the plates are with the numbers. The questions come in, and then you shoot the board with the matching answer. If you have the right answer, there will be three balloons that you can pop.

# data[].attributes.attachment_link.description
Here you can play Times Tables Shooting to practice the multiplication tables in a fun way. Learn all the tables by playing multiplication games.
