Where Mystery of the Lamp Treasure Oasis High Line sits in IGT's range
Mystery of the Lamp Treasure Oasis High Line is part of IGT's Mystery of the line, which runs to 8 documented titles. Manufacturers ship a hit as a family rather than one box, so entries in a series share branding and often a bonus structure while carrying different maths.
Mystery of the Lamp Treasure Oasis High Line is a Class II machine — that changes the question
Under the Indian Gaming Regulatory Act of 1988, Class II covers bingo and games that are technologically aided bingo. This machine is legally a bingo terminal. Every play enters a bingo game shared with other players on the same system, and the outcome is decided by that draw — the spinning reels are an animation that reveals a result already determined.
That is why "what is the RTP of this machine" doesn't map cleanly onto a Class II title. Return depends on the bingo pool, the prize schedule and how many terminals are competing in each draw — none of which live inside this cabinet.
Class II is what allows tribal properties to operate without a Class III compact with the state, which is why the same game title often exists in both a Class II and a Class III build with different maths behind identical artwork.
If you have played Mystery of the Lamp Treasure Oasis High Line at two properties and it felt different, this is frequently why — you may have been playing two different regulatory builds of the same title.
Where to play
We don't yet have verified floor placements for this machine. Our casino cross-reference covers 442 properties, but only through IGT's public linked-progressive data — which doesn't reach IGT titles. We would rather show nothing than guess.
Rest of the Mystery of the line
All 8 Mystery of the machines →8 titles carry this branding. They share artwork and usually a bonus structure, but each ships its own maths.
Other Class II machines from IGT
Class II titles run on a shared bingo draw rather than an independent RNG — a different product category, not just a different game.
