Mystery at the Mansion Slot NetEnt

Mystery at the Mansion is a 25-payline whodunnit video slot which runs on the NetEnt software platform. The mystery game’s scatter is the Mansion, the wild card is the Detective and the bonus symbol is the Colonel. Players are welcome to try their hand at the slot on this page for free or choose any of the NetEnt casinos from the listings to play the game for real money.

In order to begin solving the mysterious murder, players need to adjust their bet first. By clicking "Bet Level", players can choose the number of coins wagered per payline. The coin size, ranging from 0.01 to 0.5, is adjusted by pressing the "Coin Value" button. “Bet Lines” modifies the number of active paylines. While “Spin” starts the game, “Max Bet” turns the reels at the highest bet. Should players desire to play for a preset number of times without interruption, they can click “Auto”.

When 3 or more Mansions are scattered on the reels, Free Spins are activated. 3 scatters trigger 10 Free Spins, 4 scatters lead to 20 Free Spins and 5 Mansion symbols equal 30 Free Spins. Free Spin wins are tripled.

The appearance of 3 or more bonus symbols triggers the bonus game. First players need to identify the murderer, choosing out of 5 suspects. Then they need to identify the murder weapon and, lastly, players name the motive for the murder of the Colonel. There are wins every step of the way, even if the choices are wrong. If players choose correctly, then the total amount won is multiplied.

A 7500-coin jackpot will be awarded when 5 Detectives emerge on an active payline.

Mystery at the Mansion is a 5 reel 25 payline slot game from Netent software with bonus round and free spins. I hadn't played it before and the first time I did was at Kroon casino. When I started to play it, I couldn't ignore the huge similarities it has with a Rival software game called Moonlight Mystery. Not only the crime theme they both share and the similar name, but the Netent game even spins similar like this Rival game, the features it has look common too.

There is a bonus game, which starts if you get at least 3 bonus symbols from left to right. I had a few times when they weren't next together and then I didn't get a bonus round. In the bonus round you'll have to guess which of the characters is guilty in a crime, which weapon it used and for what reason. I got this bonus many times but I didn't get more than 4x bet win in any of them.

The most important feature in this game are the free spins. If you get 3 scatters, you'll play 10 spins with 3x multiplier (that happened to me a couple of times), if 4 scatters - 20 free games and 5 scatters give 30 free spins. Those last two I haven't experienced. And as in most games, there is a wild symbol too which substitutes for all wins except bonus and scatters.

I started to play 250 spins at Kroon casino, with the minimum bets of 0.25€ and within them I got few bonus rounds with not even 10x bet wins, and twice 10 free spins. At least the free spins paid decent, once it was a 16€ win but second time 9€. After that I doubled my bets in which I got 2 more bonus rounds and three times the minimum free spins so overall with this game I made a profit of 40€. Not much but not bad either.


I was a bit disappointed with this game. The look of the game wasn't the best, the payouts were decent but I just saw too many similarities in this game (even in bonus rounds and their symbols) and even though that comparing this game with Rival's Moonlight Mystery it is much better, I thought that this game was a little boring and I don't think I will play it again soon.

Mystery at the mansion it is another one net entertainment game from old their collection. This game of course is simply another one clone of other games, with just different layout and different stupid bonus game.

This game has 25 paylines, and paytable here is too similar like too other net entertainment games. For example, 5 wilds will pay x 300 total bet, 5 scatters will pay 400 x total bet and x 3 total bet. And after all there is nothing unique or really interesting, but it is should be interesting to play all this game one after one, that's why i starting my A-Z challenge playing netent games, check out my thread here on forum, probably you will be also interested in it, more people watching on me - more fun we all will take. I play this game not so many, probably one hour at all, and have some experience to say. First of all, bonus game is terrible. Idea is interesting, we should find murderer and weapon and motive for the killing, but this game never pay, best win is 20x total bet, what a shame netent, you really thought somewhere in the past that such thing can entertain someone? with payouts like 10 euro win with 2 euro bet? i am sure no. Free spins drop around once per 100 spins, and i think i never waited more than 150 spins, and this is great speed of receiving feature. Game can pay nice wins, even more than 1000 x total bet in free spins, but chances for this is something like get 5 wilds in free spins playing break da bank again slot from microgaming.

Medium variance game, with bad and stupid bonus game, but this game can pay in free spins in very rare occasions. It can be great, if not this bonus game.I of course will not play this game again, no way.

Mystery at the Mansion is a very nice detective style video slot containing a swell 25 paylines. This slot is like playing a game of "Who Dun it?" or finding out who the killer is and what the primary motive is. You will find much of that in it's bonus game so be ready to find out the killer, the murder weapon and what their motives were.

What I like to do is play for $0.75. I don't feel that taking things higher makes any more sense than it does with 3 coins. Sounds like it does but for me it doesn't. $0.75 is my star bet for Mystery of the Mansion. I like the Wild Detectives, they shine a spotlight on the word wild along with question marks surrounding the detective. I would feel like that too if I were to investigate or feel frightened if the killer is nearby (gasping for air). In my $0.75 bets there were a bunch of small wins however when wilds appear they improve the circumstances especially when there are more than one! There's nothing special in these wilds rather than the dramatic noise it makes when hit so don't worry about it.

On a more dramatic talk, the scattered mansions are what got me to laugh! Imao the dramatic music while nearing the end....clouding the moon and cueing lightning....Ha, what an awesome idea! Some of my wins had like $3 or less and the wild ∧ scatter symbols on one spin remixed there tunes giving this interesting harmonizing conclusion to my spin. A nice "Who did this!?" with "sounds of lightning". It was weird and it works! In the bonus game, it can be complex because they are left to right scatter symbols. When the colonel symbols hit, they show him screaming in the dark and showing him lying dead in his own blood. This is where I pick a suspect to award a win, the object posing as the murder weapon and why the killer killed.....was it for money or for love? At the end the results will be tallied and any picks that were true will each receive a 2x multiplier to be used on the total win. My total is strictly $1.95. I got the killer right as the butler and the motive correct but I missed the murder weapon to get a full 6x. It was the dagger dug into the letter but I chose the candle holders. Only $7.80 was won from my efforts.

The Free spins is a nice way to make up for the bonus however because it gave up $25.78 for my $0.75 triggering bet. The next trigger I had after my 10 free spins ended had only $15.15 for me. I guess the more I win the lower wins it gives in the future. A very nice slot to play on as well as a way to cheer up with. Everything like the tunes for when I win something or wild/scatter symbols are a laughing matter, I liked it alot, so dramatic, gloomy and weird! Mystery at the Mansion gets an 8.8 out of 10! Dun dun DUNNNNN (screams at the dead body)!
