It’s a Mystery! Slots
It’s a Mystery! is a dramatic murder mystery/crime-themed online video slot game and comes with some unusual and quite brilliant features, including the incredible Portrait Puzzle feature which holds a lot of suspense. There are also two attractive progressive jackpots: minor starting at $100 and major at $1,000. These can be won on any random spin regardless of the wager. If players find the perpetrator quickly, they can win a top jackpot of $37,500 for matching 5 question mark wild symbols on any payline.
This thrilling slot features well-known detectives such as Sherlock Holmes and Hercules Poirot, or the classic Cluedo board game. Released by RTG (Real Time Gaming) back in January 2011, it has become a clear player favorite across numerous casinos. Players help these detectives search for clues to solve the cold-blooded murder, where conspiracy, intrigue, and dark secrets lurk everywhere.
Super experienced game crafters RTG show why they are at the forefront of slots play. Every part of this ingenious game brings suspense, thrills, and excitement with free spins and multipliers in addition to generous cash prizes—like $25,000 from scatters.
Gameplay Basics
Gameplay is simple and uncomplicated, with smooth and intuitive navigation. The graphics, realized in 3D, are beautifully engineered and spectacularly shown in rich colors. The suspenseful audio soundtrack adds to the intrigue. Other highlights include instant playability, high payouts with high volatility, and innovative, engaging side games.
The mansion setting features a 5x3 grid with 25 fixed paylines. Wins require 2 to 5 matching symbols consecutively on adjacent reels from left to right. Autoplay lets you select spin numbers. High volatility attracts risk-loving players; RTP is 96.79%.
Symbols and Wilds
The wild is a green and yellow question mark that substitutes for all symbols except scatters—the It’s a Mystery! logo with a magnifying glass. 3+ scatters anywhere trigger free spins. Wilds appear regularly, creating wins—especially 5 on a payline for the top jackpot. Higher wagers mean heftier prizes.
Betting Options
Wagers range from a minimum of $0.25 to a maximum of $125, accommodating high rollers, novices, and casual players.
Symbols perfectly fit the detective theme: pipe-smoking detective, blonde-haired lady (1,250x for 5), yellow-suited man (2,500x for 5), butler (1,000x for 5), and card icons A-9 (250x to 150x for 5).
Special Features
The Feature Guarantee Meter awards a bonus automatically after 150 spins without one, giving players another chance. The Win-Win Feature applies to free spins: if under 10x the bet, get a 100x total bet multiplier.
Portrait Puzzle Feature
Triggered by 3+ scatters, this divides into 2 rounds to set free spins and multiplier. A 9-piece portrait shuffles 3 times per round. Correct-position pieces lock; others re-shuffle based on scatters. Ends with 5 to 50 free spins per correct pieces. Completing the portrait awards a 500x multiplier. 3+ scatters in free spins add 10 more.
It’s a Mystery! slot delivers lots of action with great prizes and is fully mobile-optimized. Enjoy seamless play on desktop, tablet, or smartphone—Android, iOS, Apple, or Samsung—anytime, anywhere.
