Slots Tracker: Play’n GO continues Q4 2021 form into 2022
Book of Dead retains number one slot in iGaming Tracker rankings as two debutants break top six


Book of Dead by Play’n GO made it three months in a row atop the iGaming Tracker rankings after toppling NetEnt’s Starburst in October 2021.
Book of Dead remains the top-ranked title with Starburst retaining its silver medal position.
Pragmatic Play’s Christmas Big Bass Bonanza made a stunning debut following its release on 17 November to finish in third place.
Pragmatic Play’s Big Bass Bonanza and Big Time Gaming’s Bonanza both fell one position to fourth and fifth, respectively.
Play’n GO’s Legacy of Dead, which finished fifth in November, slipped two places to seventh in December.
There were four new entrants in the October rankings including Pragmatic Play’s Christmas Big Bass Bonanza finishing in third with Evolution’s Jingle Ways Megaways securing sixth place.
Evolution’s Dynamite Riches Megaways, which was 12th in November, was the highest-ranking title to fall out of the rankings completely.
iGaming Tracker has also detailed the top-ranking new slots that were released in November and December.
Pragmatic Play’s Christmas Big Bass Bonanza secured top spot in the new games rankings from last month having gone live on 17 November.
Evolution’s Jingle Ways Megaways was the second-highest ranking new release with Book of Fallen by Pragmatic Play in third place.
The game with the latest release date to secure a spot in the top 20 was NetEnt’s Silverback Gold (15 December) after finishing in eighth 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 24 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.
