A gimmick is a clever trick or idea used to attract attention or interest. It's often something flashy and attention-grabbing.
You might hear people talk about a new restaurant using a gimmick like a giant slide from their second floor to get customers excited and take some cool Instagram photos. Or, a company might create a limited-time offer with a gimmick that says "buy one get one free" just for the weekend to draw in more customers. Sometimes, a product's packaging or design is used as a gimmick to make it stand out on store shelves. The point of a gimmick is usually to get people talking and increase sales, even if it might not be something you'd actually use or keep once the initial excitement wears off.
A trick or device used to attain some end.
Example: The box had a gimmick to make the coin appear to vanish.
To rig or set up with a trick or device.
