Best Online Slot Tournaments in 2021
Choosing a slot tournament comes down to the format: pay an entry amount to join, or opt into a leaderboard contest while playing slots.
Leaderboard formats commonly set a minimum stake for each spin, and both tournament styles limit play to designated video slots. So where did the review find these contests? The examples below outline the online tournament options it covered.
Betfair Buy-In Slot Tournaments

Buy-in contests, where players pay to enter and then receive a fixed number of spins, are commonly offered by online casinos.
Betfair was presented as a prominent, established name in online casinos. To enter one of its slot tournaments, select an affordable buy-in, wait for the scheduled start, then use your spins on the reels until they are gone.

Each competitor uses the same stake per spin throughout the contest. At the finish, the standings favour players who have collected the most multipliers.
888 Casino Slot Races

In the review, 888 Casino slot races had no buy-in: players wagered cash to collect points. To take part, go to the 888 ‘Slot Races’ lobby, pick the next race and wait for it to start.
Each race specifies both a minimum stake per spin and a spin cap. The review’s example was Max spins: 200 and Min Bet: 0.20, for a total stake of 40.00 if every spin is used. Slot wins still pay as they would outside the race; the added contest element is earning points for multipliers within the limit, which can affect a leaderboard prize.
During a race, ‘Monster Win’ and ‘Super Booster’ features may also award points, potentially moving a player into a prize-winning position on the 888 leaderboard.
Pragmatic Play Drop & Wins Leaderboards

Players who want to stake cash on each spin and also have a chance at additional prize money can look for casinos featuring Pragmatic Play games. The review said these titles appeared at most of the online casinos it had covered.

At the time of the review, the Drop & Wins + Leaderboard promotion was in its second phase and advertised €500,000 in monthly prizes at most casinos with Pragmatic Play titles. A substantial share was assigned to weekly leaderboard contests using popular video slots. Eligible spins had to be on video slots displaying the ‘Drop & Wins’ logos, at €0.50 each.
The leaderboard offered several cash-prize positions with 0x wagering requirements. During the 7-day contest, placement depended on the highest multiplier wins recorded. Since points were based on multipliers rather than cash won, the review said the scoring gave players a fair chance regardless of winnings.
Rounding Up the Best Online Slot Tournaments
The review outlined two ways to play online slots tournaments: pay a buy-in and compete for a prize pool, or enter a casino leaderboard promotion. Many of the formats discussed ranked players by multiplier wins rather than cash won, which could make the contest less dependent on stake size and open it to more than high rollers. The review also named Casino Cruise as an example of a casino with tournaments where players could raise their stakes against the competition.
