Magical Interlude

See inside

Ask someone to think of a number between 1 and 31.
Ask them if their selected number is on the card?
If it is on the card make a note of the card number and add them up.
Click each card to see the next one.
The number of all the added up cards will be their number!

Can you add some code that:
Asks them think of a number. Asks if their number is on each card? Reveal their number at the end.

Can you work out how this works?

Notes and Credits

What do you notices about the card numbers?
