The lady I share my tutor group plays this game a lot with our kids and asked if any software existed that would make it easier. I had a look around and couldn't find anything very good so I made this :)
The idea is to divide into 2 teams and ask quiz style questions. The answers should, but don't have to, start with the letter of the block selected. The team that gets the question correct then wins the block. You can have the winning team to be the first to get 4/5 in a row or the team with the most colours on the board.
Click on the colour that you need with the cursor.
Click on the block that you need to change.
If you want to start again then click RESET.
You will need Adobe Flash Player for this software to run.
If you use the slide in a PowerPoint then make sure the flash file is in the same folder.
