The game was released in early 2016 and immediately became popular, and remains popular to this day as one of better NetEnt titles. The Hawaiian theme does wonders for this slot, and the gameplay and theoretical return to player (RTP) of 96.42% further make the case that this is one awesome slot game. Variance is medium so the game is still just as easy to play as most NetEnt title, with a difference that Aloha! Cluster Pays does give you a chance to win big on any spin, and therefore shouldn't be overlooked by fans of high variance slots either. Main game and paytable The game is played on a huge 6x5 board, and immediately I liked the overall feel of the game. Graphics are excellent, board is huge, and some symbols are two rows high, including the Free Spins Scatter. All this makes Aloha! Cluster Pays one of the more pleasant surprises when you click to actually start the game. Impressive. There are no paylines in Aloha! Cluster Pays, as it's the clusters that form wins. A symbol is part of a cluster if it's horizontally or vertically attached to the same symbol, and it takes a cluster of 9 or more symbols to land a win. Since the board is 6x5, the biggest possible cluster is 30 symbols, and this is reflected in the paytable that lists the prizes for all cluster sizes from 9 to 30 for each symbol. The best possible prize, for 30x Red Totem, is 10,000 coins. For comparison, for a cluster of 9 symbols the prizes are 5 coins for each of the four low-value symbols, and 20 or 30 coins for the three high-value symbols. The three high-value Totem symbols are stacked and always appear two rows high. There is a Wild symbol that will transform into an adjacent symbol that would create the best possible cluster. Also, a cluster win can randomly trigger the Sticky Win Re-Spins. When this feature is triggered, the cluster will stick while the remaining symbols will re-spin to give you a chance to attach more symbols to the cluster. If that should happen, another re-spin would be awarded until there are no new symbols added to the cluster. Bonus features Free Spins Scatter symbol is a bit different here as it's two rows high, and the number of individual symbols counts, so the maximum number of Scatters you can land is actually six. You need to land at least three Scatter symbols – this can be one double symbol and one solo symbol – and for that you'll get 9 free spins. For more Scatters you'll get 10, 11 or 12 symbols, the latter is the prize for six Scatters. Free spins can be re-triggered with three to six Scatters, but the prizes are greatly diminished as instead of 9 to 12 free spins the prize will be between 1 and 4 extra free spins. During the free spins, Symbol Drop will be active, and low-pay symbols will be gradually removed from the board, greatly increasing the chance of landing a good cluster with high-pay symbol. If there is no win on the last free spin, the game will give you additional spins until a win occurs. There's a chance of winning big during the free spins game, as this is where the huge clusters of high-win symbols are much more possible than in the main game. Conclusion I liked this innovative game a lot. The interesting game mechanics make the experience different than playing a standard slot, and it all works so well together. The game can also pay big wins anytime because of the paytable that goes up to 10,000 coins, and because low-win symbols are removed from the free spins game. Excellent title by NetEnt and a slot game definitely worth playing.
