One of the nice things about the games available at Platipus Gaming casinos is that they cover a lot of different bases when it comes to their slot offering. With the Crystal Sevens slot, they show that they can use classic slot themes in a more modern package and format, and that leads to a high hit-rate style of play that also has a low volatility and that is perfect for players who want smooth gameplay without a bunch of swings to worry about. Unlike many three-reel titles, however, this one is packed with bonus features that give extra ways to win.
The layout here is simple and designed for a high level of action and hit-rate. There are 50 total paylines jam-packed into five reels and three rows of play. As for how bet sizing is determined, you can change the value of your bet per payline, but you cannot change how many paylines are active. Since you can change the bet line wagers to a number of options ranging from $0.01 to $2 apiece, the total betting range is $0.50 to $100, and we think that's a wide enough range to cover pretty much anything that most players would be looking for.
Wild Symbol Payouts
There are two symbols that are the most important by far in this game. The first of those is the wild, and it will help players to increase their hit-rate by picking up wins that would have been missed without them. This is obviously a serious contribution to your bottom line, but it also helps to keep the hit-rate up and the volatility down. Aside from that, it appears on all reels, which is even better compared to the more limited wild symbols that players will sometimes see from other titles.
Some solid payouts are available from this symbol as well. Five of a kind of these wilds on a payline gets you a win of 500x, which is the largest payout that you can get on a single payline during the regular game mode. From there, four of a kind is worth 150x, and you can pick up 50x for three as well. Even just two of a kind is worth 10x. Note that these wins are based on the premise that a larger payout wouldn't be available on the same payline. If there is, then you will get the single biggest prize available on a per-payline basis.
Diamond Bonus Symbols
Diamonds appear on the first, third and fifth row, and they give you a shot at a bonus feature whenever you get three on the reels at the same time. The diamonds on the first and third reels will always be white, but there are blue, green and purple ones on the fifth reel. The color of the fifth-reel diamond is what determines the bonus feature you get, so it's essentially random.
The fruity miracle bonus round gives you a pick-a-box style option where you'll get instant wins. The wild fruits bonus pays out up to 17 free spins with extras added on like expanding wilds, sticky wilds or stacked wilds. Finally, there's the lucky pick bonus that gives away free spins with multipliers based on your picks on a mystery grid of hidden symbols.
Payouts and Prizes
The purple lucky seven earns you 400x for five of a kind, and you can make that 300x for five of the blue seven. The green seven is the lowest of the three, and it's worth 250x for five.
From there, we drop down to the fruit symbols. Bananas get players 200x for five, and five of a kind of the watermelon symbols pay out 150x. A 100x prize is available for five of a kind combinations of oranges, plums or bunches of grapes. Finally, this drops to 50x for five lemons or cherries.
What the Crystal Sevens game brings to the table is a strong presentation of classic slot themes in a way that has been brought up-to-date for the modern era. The fact that this title has so many paylines and some symbols that pay for just two of a kind show that they wanted a good, balanced style of play that wasn't too top-heavy. With that having been said, there are still plenty of opportunities to pick up some strong wins, particularly in the free spins bonus features. Being feature-rich helps this title as well, and it gives it enough excitement to stand out from other titles in the sub-genre.
