A slot (plural: slots) is a dynamic item that waits for or calls out for content from a repository or from a renderer.

Invented by Charles Fey in 1887, the slot machine was a hit and soon found its way into casino floors around the world. Slots have simple mechanics and can have many pay lines that make winning possible, as well as bonus features that bring more payouts.

The goal is to line up matching symbols on the paylines. The more symbols that are aligned in a row, the bigger the win. Getting greedy or betting more than you can afford to lose are the two biggest pitfalls while playing slots, and can turn what should be a fun and relaxing experience into something that will give you a headache.
