Best online slots bonuses

Below we list the best online slots bonuses currently available at casinos. These bonuses cover both traditional three-reel slots and the latest five-reel video slots. In very general terms, the older style three-reel slots offer a lower variance while playing so your bankroll does not fluctuate as much, and the video slots offer higher variance along with extra features such as bonus rounds and free spins.

There are two main types of slots bonus:

  • Cashable slots bonuses: bonuses you can keep after meeting wager requirements (marked in the "Cash" column below).
  • Non-cashable (or "sticky") slots bonuses: bonuses you can wager and keep winnings, but you cannot keep the bonus.
