Changing variables: Scoreboard

An arena scoreboard rolls to each new value as your code runs.

What you'll learn

• Putting in a new value
• Changing a value using itself
• A shortcut: += and -=
• Copying and swapping

Each idea opens with a short narrated video, about 2 minutes in all. Then you put it to work in the game.

The six levels

1. New Score Change it
2. Scoring Points Copy and type
3. Bonus Points Fill the gap
4. A Whole Round Write it
5. Swap the Scores Fix it
6. Final Match Boss level

The levels go from changing one word, to writing the code on your own. The boss level changes every time you play.
