Every pack rip is a tiny lottery, but it is not a shapeless one. Pokémon packs are collated: each card position (collectors call them slots) has its own rules about what can appear there. Once you know the slots, pull rates stop being mysterious and start being math.
Want to feel the odds instead of reading them? Our free Pack Simulator rips packs from every English set with this exact slot structure and real market prices on every card.
The anatomy of a modern pack
A Scarlet & Violet era pack (2023-2025) holds 12 physical cards, and each one comes from a fixed slot:
| Slot | What can appear |
|---|---|
| 4 commons | any common in the set |
| 3 uncommons | any uncommon |
| Reverse holo slot 1 | a reverse holo of almost any card |
| Reverse holo slot 2 | a reverse holo, OR an Illustration Rare, Special Illustration Rare, ACE SPEC, or pattern foil |
| Rare slot | a holo rare, Double Rare (ex), Ultra Rare (full art), or Hyper Rare (gold) |
| Extras | a basic energy and a code card |
Two things follow from this that most people get wrong:
- The pack is ordered. The rarest card sits at the back. That slow last-card flip is real collation, not superstition.
- The two upgrade slots roll independently. The second reverse slot and the rare slot each decide their own contents, which is why a single pack can hold a Special Illustration Rare AND an Ultra Rare. One hit does not use up the other's chance.
Mega Evolution era packs (late 2025 onward) keep the same shape but drop one filler card (you get an energy or a code card, not both), retire the pattern foils and ACE SPECs, and add the Mega Hyper Rare, a chase card so rare it shows up around once per 1,260 packs.
Real odds, by the numbers
Published data from large opened-pack samples puts the base Scarlet & Violet set at roughly:
| Pull | Odds per pack |
|---|---|
| Double Rare (ex) | 1 in 7 |
| Illustration Rare | 1 in 13 |
| Ultra Rare (full art) | 1 in 15 |
| Special Illustration Rare | 1 in 32 |
| Hyper Rare (gold) | 1 in 54 |
The catch: these numbers move set to set. Temporal Forces stretched Special Illustration Rares to about 1 in 86 packs. Prismatic Evolutions removed Illustration Rares entirely and added Poké Ball and Master Ball pattern foils in the reverse slots instead. Reading a set's actual odds before you buy a box is the single best way to calibrate expectations.
How packs changed over the eras
- 1999-2003 (Base Set through Skyridge): 11 cards, no reverse holos until Legendary Collection in 2002. The rare slot was a holo about 1 time in 3.
- 2003-2019 (EX through Sun & Moon): the reverse holo becomes a guaranteed slot in every pack, pack size settles at 9-10 cards, and chase tiers (ex, Lv.X, GX, full arts, rainbows) live as upgrades to the rare slot.
- 2020-2023 (Sword & Shield): V and VMAX push hit rates up, alt arts become the chase, and late sets add Trainer Gallery subsets that appear in the reverse slot.
- 2023 onward (Scarlet & Violet, Mega Evolution): every rare is now a holo, packs carry two reverse slots, and Illustration Rares give even bulk-heavy packs a shot at something pretty.
Why "expected value" rarely beats the pack price
Add up (odds of each hit) times (its market price) plus the bulk, and most sealed product returns less than it costs. That is by design: the fun is variance. If you want to experience the variance without the spend, rip a few hundred simulated packs and watch the session tracker. Seeing the house edge play out in real prices is the fastest lesson in why singles are almost always the cheaper way to finish a set. And when you do hit in real life, scan the card to price it before you sleeve it.
