The Stackin Kracken 7s slot game combines low volatility with a low RTP of 95%, which means that, while the house might have a slight edge over you, this game is ideal for the more risk-averse type of player as well as players with a limited budget. Low-variance games provide more frequent wins in shorter bursts, but as in the case of the Stackin Kracken 7s slot online, these stats don’t always apply to every individual player. The Stackin Kracken 7s online slot is quite minimal as symbols go because there are only a handful of them. However, these regular symbols are very generous, from the anchor to the compass to the oyster and of course to the Lucky Number Seven with a tentacle. The latter pays out an impressive amount of 2000x for a full line of five symbols. What might be a tad confusing are the various Lucky Number Seven variants on display, with some featuring waves and others featuring a few more tentacles. Meanwhile, the treasure chest is the wild symbol and can substitute for any missing regular symbols in a line. It also pays out a handsome amount of 50,000 if you score a five-of-a-kind combination of wilds. There is no free spins round in the Stackin Kracken 7s slot machine, but it does have a solid set of features. Randomly triggered after non-winning spins, respins can be activated up to three times. Another bonus during non-winning spins is the nudge feature, where a random symbol is chosen and nudged over up to three times to help you score a winning combination.
