Casino slots game Skulls Heap by Microgaming for free

Casino slots game Skulls Heap by Microgaming for free
The Mexican 'Day of the Dead' holiday, held at the beginning of November, is the topic of this 2021’s release by the newest formed partnership: Microgaming Company and Bulgarian-based Gong Gaming Technologies Studio. As we all know, the special feast day involves relatives and close friends congregating, offering prayer and commemorating their dear departed, sprucing their graves candles, marigolds, sugar skulls and foods, trying to please and attract the spirits. In addition, special altars are being set up, sugar fiestas and parades are organized with costumes and decorations, full of music, dancing and dining. We advise you to try the Thunderstruck Wild Lightning slot by Microgaming for free.

The Skulls Heap slot machine glorifying this celebration comes with High Volatility, sufficient RTP of 96.04%, and 4096 win ways across a 6x4 playing field. In addition, the developers equipped the machine with the possibility for up to 100 Free Spins and up to x5 random Wild Multipliers. Finally, they lifted the maximum prospect of the game to a whopping 3000x the total bet (240 000 CAD via the max bet of 80 CAD). The slot seems pretty straightforward, but there’s enough ludicrous action and win potential to keep the players coming back to heap more skulls and pile more cash.

Personal testers’ opinion

  • The game is magnificently executed: the colours, the soundtrack, the funny Mexican exclamations of cheering and counting, the whole humoristic vibe on the background with a full-blown hurly-burly patting you on the back for Big and Huge Wins. The gameplay is suave and simple. It is providing premium entertainment, and we enjoyed testing it. OK, we hear the complaints that the Bonus symbols take too long to unfold on all reels, but hey, nothing is perfect in this world, even our favourite games.
  • The Skulls Heap machine offers a common multiway-game provision, where the Wilds and the Scatters deliver no payout (only operate as substitution or bonus launching), and the other 10 symbols on the paytable are divided as follows: 5 Día de Muertos (high-value) symbols and 5 cards (low-value) symbols. The first group pays from 7.5x to 5x for 6OAK on adjacent reels and carries provisions for 2OAK. The second group pays from 3.75x to 2.5x the total bet for 6OAK on adjacent reels.

The Skulls Heap is a fresh game, so we didn’t have much time to test it. However, till now, we actually won numerous times: not epic amounts, just decent (between 230x and 250x the total bet), so we only have sweet 'sugar skulls' memories to cherish. All in all, this is a fiesta we don’t want to miss! Unfortunately, due to the high variance and long cycle, with unpredictable and unbalanced gameplay, we will infer that the slot is not proper to fulfill the wagering conditions on the bonus money.
