Star Clusters Megaclusters starts by default on a playing field of 4 x 4 symbols. You bet from 0.20 euros per spin and that goes up to 20 euros per spin.
The payout percentage is an excellent 96.54%. Fortunately, Big Time Gaming is not going along with the trend to use ever lower payout percentages on online slots. The variance is high.
As mentioned, you win a prize as soon as you make a winning combination of 5 or more of the same symbols. A respin feature is then started, where all single symbols that are part of the winning combination are split into four symbols. As long as you make winning combinations, you will continue to get free respins. It definitely takes some getting used to with all those splitting symbols.
Where with Megaways slots you immediately see which winning combinations there are and especially which symbols you need to make a new winning combination, with Star Clusters Megaclusters it is a lot more cluttered.
In addition, the tempo is also quite high, which makes it even more difficult in the beginning. Yet you will get it all by yourself, even if it remains much less intuitive than with the aforementioned Megaways slots.

The regular symbols consist of seven jewels, all of which have a different colour: purple, red, blue, green, orange, yellow and turquoise.
The purple, red and blue colored jewels pay the most, with the purple leading the way. A cluster of 25 or more purple jewels will give you 50x the stake. In addition to the normal symbols, there are also two wilds in the game (both are stars): Regular Wilds substitute for all symbols.
Gold Wilds have a multiplier and a maximum of 2 Gold Wilds can appear on the screen. As soon as you make a winning combination with a Gold Wild in it, the multiplier increases by +1. This multiplier remains as long as you keep making winning combinations.
Can you activate the free spins bonus? Then the current multiplier is carried over to the free spins. That could come in very handy.

You win the free spins bonus if you manage to make 5 or more winning combinations in a row.
Five winning combinations gives 2 free spins and every winning combination after that is good for +1 free spin.
In addition, the multiplier built up during the base game is included as the starting multiplier.
Winning combinations with Gold Wilds in them will give you extra multipliers and tapping a multiple of x 10 will give you another +2 extra spins.
But we haven't even mentioned the most important thing yet. The playing field is enlarged from 4 x 4 symbols to 8 x 8. Because every symbol can also split into four smaller symbols during the free spins, you can make a playing field with a maximum size of 16 x 16 symbols.
The game was already hard to follow at times and that only gets more difficult during the free spins.
Everything is happening and left and right, up and down you will get winning combinations. It may feel a bit dizzy, but it's best to surrender yourself to it. As long as that multiplier increases and your spin after spin picks up a big payout, it will be worst for you too.
