Same-game rule: books price multi-leg same-game parlays with proprietary correlation models, not by multiplying the leg odds. To stay honest, this tool keeps it cross-game only — if you build a parlay that includes legs from the same game, the per-book comparison may diverge from what the book actually quotes at checkout.
