Where earlier drafts were corrected. An earlier version of this review described Royal Express as triggering its bonus with «six or more coin symbols» on a standard multi-line grid. That matched the generic Hold and Win template, not this title. It has been replaced with the verified 3x3 mechanic: Bonus symbols on reels 1 and 3 plus a Train Boost symbol on reel 2, with Pile of Gold as the random alternative trigger. Publishing the correction openly is part of our editorial standard.
