Peek-A-Boo slot from Microgaming

Peek-A-Boo slot from Microgaming
This 2015 Microgaming release should preferably be played on Halloween night, but naturally, cute ghosts are all around us throughout the whole year, so no need to wait or hesitate. Peek-A-Boo slot machine takes you on a hunt for 4 comical ghosts with a sweet tooth. Together with a courageous hero with a big zap gun, you scour the reels for ghosts, destroy them to pieces, and collect their remains in the ghost meter. Zapping 10 of them will be awarded Free Spins where Wilds are super-stacked, and the pay lines are increased from 40 to 1024. We advise you to try the Thunderstruck Wild Lightning slot by Microgaming for free.

In the meantime, many candies are flying around for you to collect, while the hunting pleasure is intensified by the eerie sound effects and haunting soundtrack. This colourful slot is equally entertaining, suspenseful and cheerful for all players, but especially for those who get goosebumps when they hear the classic phrase: Who you gonna call?! Ghostbusters!

With a Low Volatility, generous RTP of 96.59% and the promise of a 100 000 coins max win, there’s nothing to be panic about as you spin the ghostly reels of the Peek-A-Boo slot machine.

Personal testers’ opinion

While testing this amusing slot, we were immediately thrown back in time to the first time Ghostbusters entered our young minds. So, positive vibes all over again. We soon realized the slot does keep the balance well, which makes it suitable for completing the bonus requirements. The hit probability is high at 39.91%, which means every 4 out of 10 spins will bring some payout. So, it can be lower than the stake, but a hit is still a hit. 79% of the total prize pool is reserved for the main game, so we didn’t expect big wins during the Free Spins, for which one has to wait pretty long (statistically, after 155 spins is expected one bonus round). And so it happened. We needed a big dose of patience before triggering the Free Spins, plus our testing team ever registered no large win. Nor did we hit a massive amount in the base game. Therefore we can only leave neutral recommendations for the Peek-A-Boo slot machine regarding playing with real credits.

Hidden parameters of Peek A Boo slot

  • The frequency of triggering the bonus is statistically every 155th spins (0.64%).
  • The probability of a hit (any winning) is 39,91%.
  • The distribution of the winnings is 79% in the usual spins and 21% in the bonus.
  • The maximum payout during the tests was 61x.
  • The average winning from the bonus was 31x.
  • Volatility is 3,55 out of 20 (low).
  • Cycle length - short.
  • The rating of the slot machine for the wager is 8 out of 10.


  • Wild Peek-A-Boo Logo - Replaces all other symbols and appears stacked on each reel in the main game. In Free Spins, it’s even super-stacked, but only on reels 4 and 5.
  • Free Spins - To launch 10 (to 13) Free Spins, our little Hero has to collect 10 ghosts by terminating them to pieces. Only when the Hero lands on reel 3, he can aim at the ghosts, and unfortunately, he only has enough ammunition to take down 1 ghost per reel. When the ghost collector is filled to the top, the Free Spins are triggered, and the regular 40 pay lines are switched to 1024, while the Spooky Re-spin will kick in. Whenever there’s a 3 or 4 symbol win, the winning reels are frozen, while a re-spin will give you one additional chance to collect 1 or 2 more winning symbols to your initial win.


  • Tip. It is better not to use the maximum bet size. You should stop your decision at the minimum value. And everything because this slot does not tend to give out the big winning so often.
  • The expected percentage of the payment is not known.
  • The maximum possible payment for one spin is 100 000 coins (only on the condition that there is the highest bet).
  • Bonuses. The main feature of the machine is the way to trigger free spins. You are being waited for 13 spins of the reels with the Spooky Re-spin function, which significantly increases your chances of winning.
  • Recommendations. For sure, the range of bets and multipliers for the pay combinations do not match each other; it is better to limit yourself in this slot machine. If there are empty spins for a long time, it will be better not to continue to bet.
