Packsim

The booster's contents follow the official Riftbound documentation — Riftbound official docs · Get started. Original: “premium packs filled with 7 Commons, 3 Uncommons, 2 foil Rares or better, 1 foil of any rarity, and 1 token slot”. The 24-pack display and the box averages (more than 6 epics · more than 2 special alt-arts) are the wording of Riot Merch · Riftbound Origins Booster Display. The simulator's 14-slot table is an estimate fitted to those averages, not an official odds table, and it does not match the official document's slot breakdown exactly.

Per display (24 packs) the rare-or-better slots avoid cards the same box has already dealt — an anti-repeat heuristic that is also an estimate, not official collation. When the undealt cards run out, the draw falls back to a uniform pick.

The Nexus Night promo pack has 3 cards printed on its wrapper (TCGPlayer products 675404 · 680454), and those 3 cards are all that is confirmed. No table of the slot weights inside the 3 is published, so the simulator draws uniformly from that set's Nexus Night cards — an estimate. The premium pack's 7/3/2/1/1 breakdown does not apply to a 3-card promo pack.
