Counting and adding up: Piggy Bank

Coins drop in one at a time, and the total climbs as your code runs.

What you'll learn

• Adding things up
• Adding the loop variable
• Counting only some things
• A total and a count together
• Starting the total in the wrong place

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. Bigger Coins Change it
2. 1 to 10 Copy and type
3. Only the Evens Fill the gap
4. Fives Only Write it
5. Vanishing Coins Fix it
6. A Random Pile Boss level

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