ROI & Statistics
ROI Advantage is the difference between the Current ROI and the Original ROI. It shows how the game's value has shifted since launch.
- Positive (Advantage) — More high-value prizes remain relative to the number of tickets left. The game is statistically better to play now than at launch.
- Negative (Disadvantage) — Fewer high-value prizes remain relative to tickets. The game is statistically worse than at launch.
On the Catalog page, the ROI bar visualizes this: green fills right of the midpoint for an advantage, red fills left for a disadvantage, with the original ROI shown at the center.
