Yu-Gi-Oh! Pack Opener & Simulator
Flip open virtual booster packs from real Yu-Gi-Oh! TCG sets — 4 Commons and a foil slot with realistic pull odds. Free, no sign-up, and every pull can be saved to your collection or shared.
Ready to open packs
Pick a set and hit Open 1 Pack — every pack has 5 cards: 4 Commons and 1 foil slot.
What Is a Yu-Gi-Oh! Pack Opener?
DeckPen's Pack Opener is a free online Yu-Gi-Oh! pack simulator that lets you open virtual booster packs from real Yu-Gi-Oh! sets — without spending a cent. Pick a set, hit Open 1 Pack, and watch the cards flip: Commons, Rares, Super Rares, Ultra Rares, and the chase Secret Rares. Whether you're testing your luck before buying real packs, building a digital collection, or just want the dopamine hit of pulling a shiny card, this is the fastest way to open packs online.
How Realistic Are the Pull Ratios?
Every pack in our simulator follows a real booster's structure — 4 Commons and 1 foil-slot card — and the foil slot rolls against a weighted ladder that approximates each set's actual rarity distribution. We don't rig the odds: Super Rares, Ultra Rares, Secret Rares, and the chase Starlight Rare or Quarter Century Secret Rare appear at their real-world rates. That means a Secret Rare is just as special here as it is in real life — and yes, sometimes you'll open ten packs and get nothing shiny. That's the real pack-opening experience, just without the price tag.
Which Booster Packs Can I Open?
We support every major Yu-Gi-Oh! booster set in the tool, including:
- The Infinite Forbidden
- Rage of the Abyss
- Legacy of Destruction
- Phantom Nightmare
- Blazing Dominion
- …and more, updated as new sets release.
Every set on the list uses its real card pool and rarity list — pick one in the dropdown above and open a pack right here. New core sets are added as they release.
Can I Keep the Cards I Pull?
Yes! Sign in and hit “Save to Collection” after a pack, and every card is added to your DeckPen collection with its rarity and quantity tracked. Build your digital collection pack by pack, keep track of your rarest pulls, and use your cards to build decks with our Deck Builder. It's free to get started — no credit card required.

Pull Rarities Explained
Common
The most frequent cards in every set — most of your pack will be Commons, and most of your playsets start here.
Rare
Above Common in older and side sets, with a foil name. In modern main boosters Rare cards sit between the bulk and the holo slots.
Super Rare
The first holo tier — a silver holographic treatment. In a modern booster the foil slot is a Super Rare about half the time.
Ultra Rare
A gold-foil treatment and the second holo tier — noticeably rarer than a Super, usually around one in four packs.
Secret Rare
The rainbow holographic treatment that collectors chase. Expect roughly one Secret Rare every six to eight packs.
Starlight / Quarter Century Secret
The chase rarity — Starlight Rare in recent sets, Quarter Century Secret Rare before it. Roughly one per display box, and the pull worth screenshotting.
