Crystal Sevens - Review, Demo Play, Payout, Free Spins & Bonuses

Pros & Cons

Crystal Sevens’ biggest strength is its three bonus game modes, each of which changes up gameplay in a different way so it continues feeling fresh and fun after you’ve been playing for a while. With a minimum bet of 0.5 and medium-volatility gameplay, Crystal Sevens takes a bit of investment to win big, but with fifty lines in play you’ll rarely win on just one line when you do win. Sadly, there’s no huge jackpot to win, but the base game has a good range of prizes.

Introduction

Crystal Sevens by Platipus Gaming free slots is a five-reel slots game that pays out on fifty different fixed lines. It has three different bonus games, one of which offers players a choice of three mini games. All in all it’s got a great range of gameplay modes and some tasty prizes for a modern take on a classic fruit machine experience.

Theme, Graphics & Soundtrack

Crystal Sevens is a jewel themed slots game, a little like the Crystal Burst XXL online slot.

Crystals and fruit are all over the game screen, with jewelled sevens as the Wild symbols and top prizes and large blue diamonds to trigger bonus games. It’s very luxe and very brightly coloured, and it’s a lot of fun to look at. It feels stylish and modern but still classic and not too gimmicky.

The soundtrack is soft pipe and drum music that contributes to the Ancient Egyptian feel. Bear in mind that the sound effects are a lot louder than the music, so if you’ve got the volume turned up the sound of a win can be pretty startling!

Crystal Sevens doesn’t have a soundtrack as such - just pleasant soft sounds as the reels drop into place. If you’re playing for more than a few minutes, you might appreciate that. Equally, if you’re playing with the sound off, you’re not missing much.

RTP & Volatility

The theoretical return to player is 95.03%. Crystal Sevens is a medium-volatility slots game: wins are fairly frequent, but mostly on the smaller side outside of the bonus games.

How To Play Crystal Sevens

Starting to play Crystal Sevens is as easy as pushing a button, but there are several settings and features that will help you get the most out of the game.

1. At the bottom left of the screen you’ll find the mute button (the speaker icon)
2. Click the three-line button for game information. You will find a few menus here.
3. You can use the paytable to see the prizes available as well as the game settings and rules. The history tells you how much you’ve bet and won, and there is also a fullscreen option.
4. The button showing two arrows allows you to use autospins. You can adjust the number of spins and set maximum win and loss amounts. Even the lowest settings are quite high, so be careful with these.
5. At the bottom of the screen you can set your line bet. The minimum is 0.01 and the maximum 6. Remember that as there are 50 lines, your total bet will be 50x higher than your line bet, for a maximum total bet of 50.
6. Don’t forget to play responsibly!

Bet & Win Sizes

A lot of online slots games just have players set their total bet, but Crystal Sevens sets line bets that in turn add up to the total bet. Because there are 20 lines in play, total bets are 20x higher than the line bet. Line bets range from 0.01 to 1.00, so total bets per spin range from 0.5 to 50.

The paytable shows the winnings assuming a line bet of 1.00 and doesn’t update when you change your line bet.

Red and blue 7s symbols pay out on two or more on a line.
Red 7 - x5 to x500
Blue 7 - x4 to x400
Multipliers shown are for two and five symbols.

Other winning symbols pay out on three or more on a line.
Green 7 - x25 to x250
Banana - x20 to x200
Watermelon - x15 to x150
Orange, plum, grape - x10 to x100
Lemon, cherry - x5 to x50
Multipliers shown are for three symbols and five symbols.

Crystal Sevens Bonus Features

Crystal Sevens has three bonus game modes. Which one you get depends on which bonus diamond symbols triggered the bonus mode.

The first bonus game has five levels. You click on each level in order, and when you’re done you win the number of coins you’ve revealed, multiplied by the line bet set when the bonus game triggered. Simple!

The next bonus game is scratch card style. You scratch off panels until you hit a “start free spins” symbol and hopefully hit some prize multipliers and extra free spins on the way. Once the free spins start you’ll have a minimum of five free spins and a x1 multiplier.

The third bonus game is also based around free spins, but it has three mini games to choose from:
 
•    5 Free Spins with Sticky Wilds, where Wild symbols stay on the reel until the free spins run out.
•    10 Free Spins with Expanding Wilds. If the Wild symbol appears on a reel, it fills all the spaces on that reel.
•    15 Free Spins with Stacked Wilds. The Wild symbol only appears in stacks.

Overall Review

Crystal Sevens by Platipus Games is an enjoyable medium-volatility slots game. Its bonus modes are excellent, with a great range of gameplay on offer. It’s not the only jewel themed slots game out there, but it’s a fun one.
