Marvel Snap Pack Simulator

Open simulated Marvel Snap packs using your real collection data. Pick from four pack types (Series 5 Seasonal at 5,000 tokens, Series 4 Seasonal at 2,500, Series 5 Collectors at 4,000, or Series 4 Collectors at 2,000) and see exactly what you would pull. Each pack contains one guaranteed card plus two goodie rolls that can return bonus cards, tokens, credits, boosters, mystery borders, or mystery variants. When a series is fully complete, bonus card slots convert to token fallbacks worth the pack price instead. If you sync your collection, cards you already own are removed from the pool, and cards pulled during your session leave the pool too, so your odds improve with every open.

Pity system and drop rates

The simulator models the real pity system: a per-pack-type counter tracks goodie rolls since your last bonus card, and when that counter times the combined card drop rate hits 100%, the next roll guarantees a bonus card. The pity boost works out to roughly 1.58x the raw card rate across all pack types. Drop rates come from Second Dinner's published tables and have been validated against 10,000-trial Monte Carlo simulations. Over hundreds of packs, goodie rolls reduce effective pack costs by 8 to 12% compared to the sticker price.

Pull luck tracking and batch opens

Every session builds a running pull history (up to 2,000 packs) with a Pull Luck panel that compares your actual bonus cards to the expected count and tracks god packs (two or more bonus cards from a single opening) against their expected rate. Open packs one at a time with a tap-to-reveal animation, or use batch mode to rip through 10, 100, or 1,000 packs at once and jump straight to a summary of total cards, tokens, credits, boosters, borders, and variants pulled. Use it alongside the completion planner to decide whether opening packs now or saving tokens for direct purchases gives a faster path to finishing your collection. Free accounts can open 5 packs per day. SnapComplete Premium unlocks unlimited daily opens and all batch sizes.

When should I open packs vs direct buy?

The simulator answers the question every Marvel Snap player faces at the end of a season: is it cheaper to open packs and gamble on pulling your remaining cards, or save tokens and buy them outright? Run a batch of 100 or 1,000 opens and compare the average token cost per card pulled against the direct buy price. When your unowned pool is large, packs are almost always cheaper because goodie rolls give you free bonus cards along the way. As the pool shrinks to one or two cards, direct buying becomes more efficient because you no longer benefit from the pity system. The pack sim handles this math for you by simulating against your real remaining pool, so the answer is personalized to your collection state. Pair it with the Completion Timeline to see exactly how opening a batch of packs shifts your projected completion date, and check the Pack Goodies FAQ for the full breakdown of how goodie tiers reduce effective pack costs.
