Crystal Sevens was released in 2018 for desktop and mobile devices. The game was developed by Platipus Gaming and features a 5x4 reel with 50 fixed pay lines. Thanks to the three different bonus games and a wild symbol, you will be able to reach 95% RTP. The game’s win variance is unknown.
You can bet a minimum of 0.50 and a maximum of 100 cash.
The amount you spend each spin is your ‘Total Bet’, which is calculated by multiplying the game’s 50 fixed pay lines by your selected ‘Line Bet’. If you are playing on a desktop, the ‘Line Bet’ setting is in the bottom right-hand corner; if you are playing on mobile, the setting is on the left-hand side. The options range from 0.01 - 2.
You can spin using the game’s turbo mode or automatically spin up to 100 times using the autoplay feature.
Crystal Sevens has a background filled with different crystals and a black/purple background. Every time you spin, you can hear special sounds when the reels lock into place. The payout symbols are vibrantly coloured and start to flash when you land a winning combination. You can turn off the game's music and sounds from the ‘mute’ button in the bottom left-hand corner (desktop) or from the left-hand side-menu (mobile).
Crystal Sevens has a wild symbol, three high-value 7 symbols, five mid-value fruit symbols, and two low-value fruit symbols. The wild symbol is the highest paying symbol in the game and can be combined 2, 3, 4, or 5 times to trigger payouts equal to 10, 50, 150, and 500 coins.
The high-value 7 symbols are the red, blue, and green symbols, with the red 7 offering the highest payout of up to 400 coins. Depending on your selected ‘Line bet’, the maximum cash amount you can win is 800 (400 x 2 ‘Line Bet’). The high-value symbols can be combined 2 - 5 times. Low-value symbols can only be combined 3 - 5 times.
The different ways to combine payout symbols are under the ‘Winning Paylines’ heading on the paytable.
How to Read the Paytable
The paytable lists the number of coins you win when combining the different payout symbols. To calculate the cash value of your payout, multiply the number of coins won by your selected ‘Line Bet’.
Bonus Games: There are three bonus games that can be activated by landing two bonus symbols on the 1st and 3rd reels. Depending on which special bonus Crystal symbol you land on the 5th reel, one of three games will be activated.
Bonus Game 1: If the Blue Crystal symbol appears on the 5th reel, the 1st bonus game will activate. This bonus game includes 5 levels, each level the player should select one of 6 items to proceed to the next level. The final prize amounts to a total number of coins won by the player multiplied by the bet per line.
Bonus Game 2: The free spin bonus game is activated by the Green Crystal symbol on the 5th reel. You can either win 7 free spins with sticky wild symbols, 12 free spins with expanding wild symbols, or 17 free spins with stacked wild symbols.
Bonus Game 3: The Pink Crystal symbol activates this game, where you will have to click on the squares to reveal what is hidden behind them. Among the prizes are multipliers and free spins. The base prize is 5 free spins and an x1 multiplier.
The Wild 7s symbol can substitute for all symbols except the bonus symbols and also offers payouts up to 500 coins when combined 5 times.
