Yggdrasil Gaming has adopted the Joker as it's de facto mascot, which I am not a fan of. I routinely chastise the company's Joker slots, as they are all essentially the same, with a few graphics changed here or there. This trend continues with the Dark Joker Rizes slot, which makes the Jester resemble the Joker from Batman, complete with dark themes. The game's features are pretty bare, and the RTP for the game is awful if you don't play with the maximum amount of credits.
The Dark Joker Rizes is a 5 reel, 5 payline video slot that features a dark theme reminiscent of The Dark Knight film, and gives us an evil looking Joker. The game's symbols are essentially the same as the other Jokerizer games, and include cherries, lemons, grapes, bells, 7s, and stars, all of which have a dark edge to them. The game also has a Joker symbol that serves as a random mystery win symbol, which is triggered when you land two or more on the reels.
The game's only real feature is that mystery win symbol in addition to a left to right and right to left pay structure. The game's theoretical RTP percentage varies from between a criminally low 79.7% to 96.3%, which is not impressive in the least when you consider the max RTP rate is only available when you bet the maximum 200 coins for the game or participate in the Jokerizer mode.
I played this game for a while, and found it to be nearly identical to the other Yggdrasil games with this general theme. The game is boring and you may very well expect to go a long time in between wins, as there simply isn't too much going on. The game simply isn't a great one if you don't play the max amount, and I can't recommend it to you as there are much better online slots out there.
