Mr Woo is a 2008 Aristocrat slot machine built around a 20-payline standard game with an unusually deep bonus structure layered on top: six distinct bonus games, unlocked by spelling out "MR WOO" with overlay symbols that appear over the standard reels. That combination -- a fairly modest base-game payline count paired with an outsized bonus menu -- is one of the things that made the title stand out among Aristocrat's mid-2000s slot lineup.
Released by Aristocrat in 2008, Mr Woo is a standard video slot with 20 paylines -- a relatively modest number for the era, especially compared to the 50-plus-payline and ways-to-win games that were becoming common around the same time. What sets it apart isn't the base game's line count but what sits on top of it: a set of six separate bonus games, more variety than most single slots offered.
Rather than the usual scatter-symbol trigger, Mr Woo unlocks its bonuses by spelling out the letters M-R-W-O-O using special overlay symbols that appear layered over the standard reel symbols during play. Landing enough of these letters completes the word and sends the game into one of its six bonus rounds. It's a distinctive trigger mechanic that makes the game easy to recognize once you know to watch for the overlay letters rather than a typical scatter icon.
Slot reviewers have pointed out the contrast between Mr Woo's bonus variety and its comparatively low payline count, describing 20 lines as surprisingly modest for a game carrying six different bonus games. It's a reminder that payline count alone doesn't tell you much about how feature-rich a slot actually is -- two games with the same number of lines can play very differently once their bonus structures come into it.
By 2008, Aristocrat had already built a reputation for letter- and word-based bonus triggers across several titles, and Mr Woo fits that pattern rather than breaking new ground with its core mechanic. What's harder to pin down publicly is the game's specific theme artwork and its cabinet hardware, both of which remain unconfirmed -- worth a photo if you spot it on a floor, since documentation for this particular title is thinner than for many of Aristocrat's better-known releases.
