Inspired by the X-Files and similar TV shows, this slot machine takes you to a top-secret facility that’s filled with captured alien lifeforms. For its symbols, Agent 51 slots use these colorful cartoonish aliens as the regular-paying symbols and they’re randomly displayed on a 3 by 5 playing grid. Initially, the spins happen on a board inside the office. As you enter the game’s bonus round, the action happens inside a laboratory filled with aliens in glass cases using the same grid configuration.

True to its theme, Agent 51 leads the list of the game’s paying symbols. Our agent is joined by our colorful creatures as the regular-paying symbols and colored footprints as low-paying symbols. Agent 51 serves as the game’s Wild which replaces other regular-paying symbols except for the Accumulation, Special Expanding, and Extra Free Spins symbols.
