Free spins are a common online casino bonus reserved for pokies. Some apply to specific games, while others can be used on any pokie available on the site. Essentially, as soon as you collect the free spins bonus, you can start playing your favorite pokie without investing additional money. For example, if you get 30 free spins, you’ll be able to spin the reels of a pokie 30 times for free. If you want to keep playing the game after using the bonus spins, you’ll have to make a deposit.
