The first thing you are going to notice about the Crystal Classics slot is that it takes place on a considerably bigger than usual 7x7 grid. This is because the slot utilizes a cluster pay system. For those who don’t know what this is, it is when the game pays out for symbols landing in clusters next to one another as opposed to traditional paylines. Think Candy Crush and other such mobile games to get a better idea. If you want to take the game for a spin before you play for real money, you can always try out the Crystal Classics Demo we have provided here for you.
In terms of playing the game, things are fairly standard. Players need to choose their stake using the +/- buttons with €0.20 being the minimum and €10 being the highest, presenting a fairly limited betting range that will suit those on smaller budgets. There is also an autospin feature that can take up to 50 spins for the player, though the settings on this are not adjustable.
The cluster payment system means that there are a lot of different winning combinations to keep up with. The fruit and symbols are split into two different categories – majors and minors. The highest-paying symbol is the number 7. This will reward players with a 100x total stake payout for any combination of 25 or more. It rewards 40x for 17+, 20x for 15+, 10x for 12+, 5x for 10, 3x for 9, 2.5x for 8, 2x for 7, 1.5x for 6 and 1x for 5. The star and bar are next, paying out 65x and 40x for 25+ respectively.
The minors are the apple, orange, lemon, and cherry. The apple and orange both pay out 25x for combos of 25+, while the lemon and cherry pay out 10x. These are the lowest-paying symbols on the board and offer the lowest payout, which is 0.1x for combinations of five.
There are several great Crystal Classic bonus features to take advantage of. The first of these is the cascading reels feature. This is common in cluster pays, with winning symbols being replaced by tumbling new ones. What makes this one special, however, is that a wild multiplier will randomly be added to where the winning combination took place. This can be up to 5x in the base game, and up to 100x in the free spins game.
Talking of the Crystal Classics free spins round, this is triggered whenever players manage to land four or more scatters anywhere on the reels. Four scatters will give 10 spins, five will give 15, six will give 20, and 7 will give 25. You can add more free spins during the round if three or more scatters land. If you want to skip the queue, you can use the buy free spins feature to gain access to this round early.
The Crystal Classics RTP is listed as 95.69%. This is slightly increased to 96.53% when players use the buy free spins feature. There is no volatility information available in the slot, however, we found that we did manage to land one or two big wins when playing for this Crystal Classics slot review. The wins weren’t common though, suggesting high volatility.
