Slots Tracker: Play’n GO seals half-year sweep atop rankings
Book of Dead and Starburst continue to lead the chasing pack as Pragmatic Play takes five of top 10 slots


Book of Dead secured a sixth consecutive month at the top of the iGaming Tracker slot rankings after holding off NetEnt’s Starburst once again.
Play’n GO’s Book of Dead replaced Starburst as the top slot in October 2021 and now completed a half-year sweep at the top of the table.
Pragmatic Play’s Big Bass Bonanza and Sweet Bonanza swapped places from February to March, with the latter taking the bronze medal position.
Play’n GO’s Legacy of Dead remained in fifth place, while Pragmatic Play’s Wolf Gold and Bigger Bass Bonanza were unmoved in sixth and seventh, respectively.
Play’n GO’s Reactoonz suffered the biggest downturn, dropping from ninth to 15th.
There were two new entrants in the March rankings including Microgaming’s King of Crystals and 15 Tridents by Pearfiction.
Microgaming’s Fishin Pots of Gold, which was eighth, in February, was the highest-ranking title to fall out of the rankings completely.
iGaming Tracker has also detailed the top-ranking new slots released in February and March.
Microgaming’s King of Crystals secured top spot in the new games rankings having gone live on 15 February.
Pearfiction’s 15 Tridents came second, while Fishin Frenzy Fortune Spins by Blueprint finished in third.
The game with the latest release date to secure a spot in the top 20 was Raging Rex 2 by Play’n GO (7 March) after finishing in 12th place.
The iGaming Tracker has changed its methodology of data collection and grading of games since October 2020 to give a fairer and broader reflection of the rankings.
Games are ranked by their position throughout the month on more than 500 of the largest casino sites in Europe. Only the ‘main’ page of the casinos is taken into account and the top 10 most prominent positions on those pages.
The previous number of sites the iGaming Tracker took into account was just 50.
The iGaming Tracker compiles the slots rankings by tracking casino sites across more than 25 European countries including the UK, Sweden, Germany, Italy, Norway and Denmark.
Each casino page is tracked every day over the month as well as which game occupies each position. Each position is weighted so the top positions on the page have a higher weighting than the positions on the bottom of the page.
Likewise, the pages, sites and countries are weighted to give a fairer view on the success of casino games.
Table games such as roulette and blackjack are excluded from the rankings, as are live casino games.
