This slot is themed on an off-brand X-Files agent.
Set in a ramshackled office, this game is full of mysterious aliens. Retro investigation equipment and boxes of evidence litter the room, and players will need to solve a sci-fi mystery.
The dashing and dishevelled special agent peers out at the players from his reel with a conspiratory look. Players will want to be on his team and capture an alien or two.
The sound effects only kick in when players hit spin and consist of a satisfying click and a dramatic series of notes. Wins are accompanied by a shimmering chiming. The absence of ambient sound or background music may suit some players well, as there is nothing to tire of.
Right away, players will notice the colourful and adorable alien symbols. They bring to mind the style of 2000s special effects and this ups the nostalgic vibe.
Meanwhile, the many alien footprint symbols give the reels an appropriate air of mystery. Players will enjoy imagining which extraterrestrial creatures have left each tiny print.
The dim office in the background has an air of a scattered genius about it, with a pinboard covered in clues. Light filters through an old set of blinds and gives the room a dramatic look.
Overall, the aesthetic of the game readily brings to mind the X-Files inspiration and creates an entertaining atmosphere.
Agent 51 is a 5 reel, three row slot, with 20 win lines.
Players collect accumulation symbols in a set of files above the reels.
When players hit their 10th spin, the accumulation symbols that players have collected become Special Expanding symbols. Players may land Accumulation symbols with x2 or x3 multipliers.
The Wild symbol substitutes for all symbols except the Special Expanding, Accumulation, and Extra Free Spins symbols.
Special Expanding symbols make up winning combinations in any place on a win line.
When players land 3 Wild symbols in any position, they are awarded x2 their total bet. With 4 Wild symbols players get x4 their bet, and with 5 Wild symbols they receive x20 their bet.
Landing 3 or more scattered Wild symbols awards 8 free spins to the player. The Free Spins bonus is possible to retrigger.
