Practice vertical (column) multiplication with this fun and colorful online game!

First choose the settings (below) and then you will see a colorful grid with question marks. Click any of the tiles to get an multiplication problem to solve. Once you solve all the problems, your color grid will be complete and you'll see a fun surprise!

The problems include empty boxes for you to do the regrouping, but you don't need to fill them in. These are just to help you do the multiplication; the program does not check the actual regrouping part, but just the answer.

Note: There may be more boxes than necessary. Just leave them empty.
