Diamond Queen is an IGT title you'll still find on the casino floor, not just in an online lobby. Land three scatters on reels 2, 3, and 4 and you get three free spins, but the wilds don't reset between them -- each spin locks in one more reel, so the coverage keeps building through the round.

Known quirks
Diamond Queen is a real, currently-tracked land-based cabinet: URComped's slot-machine locator page for the game shows it documented by community members 79 times, with the most recent sighting tagged at Park MGM in Las Vegas.
A player review on LCB describes the free-spins bonus as cumulative rather than resetting each spin, writing: "getting the 3 scatters on the middle 3 reels 2,3,4th reels, u get just 3 spins, but each spin has a stacked wild."
Recognition clues
Title glass or top box reading "Diamond Queen," credited to IGT (shown as "IGT (WagerWorks)" on some online listings, which is just IGT's interactive-games arm, not a different maker)
IGT G23 housing: two 23-inch screens side by side, not a single portrait or landscape monitor
Scatter symbols landing specifically on reels 2, 3, and 4 to trigger the bonus, not a scatter-anywhere trigger
During the bonus, watch for the wild coverage growing each spin -- reel 2 wild on spin one, reels 2 and 3 on spin two, reels 2 through 4 on spin three -- instead of resetting
