Right now: the best rip in That Time I Got Reincarnated as a Slime Vol.3 is the Booster Box (16 packs) at $102.88 against $125.92 of expected pulls — a +4% margin after ~15% selling fees, and a 45% chance it actually pays for itself. Figures refresh every two hours.
That Time I Got Reincarnated as a Slime Vol.3 arrived on July 21, 2023 as a standard Weiss Schwarz booster: nine cards per pack, sixteen packs per box, one rare slot and one foil hit slot. Sealed has stayed reasonably priced for a popular anime license, and the set has recently modeled near break-even rather than deeply underwater, which counts as a good result for Weiss.
The hit slot does the work. Community estimates give it a foil Rare 55% of the time, a Super Rare 25%, a Triple Rare about 1 in 8 packs, and a Special Rare or above roughly 1 in 12. The Rimuru Secret Rare is the set's single monster chase; below it sit Special Rare Benimaru, Shion and Veldora, then a broad Super Rare tier.
Only two products exist: loose packs and the 16-pack booster box, so product choice is mostly a question of per-pack price. Read the live table for the fee-adjusted margin on each and the odds a box clears its cost, remembering that the rates are community estimates and that signed and serial-numbered variants aren't modeled at all. Whether the margin still holds today is answered below.

FAQ
How many packs are in a Slime Vol.3 booster box?
Sixteen packs of nine cards each, the standard Weiss Schwarz box. Our model treats every pack as one rare slot plus one foil hit slot, with the other seven cards treated as filler.
What are the chase cards in Slime Vol.3?
The Secret Rare Rimuru, 'For a World to Live In With a Smile', is the headline pull by a wide margin. Behind it come the Special Rare Benimaru, Shion and Veldora, then the strongest Super Rares such as 'Battle-Hungry, Shion'.
Are Slime Vol.3 pull rates official?
No. Bushiroad doesn't publish Weiss Schwarz pull ratios, so the hit-slot percentages here are community estimates. Signed and serial-numbered variants aren't modeled, so any such pull would be a bonus on top of the EV shown.
What are the odds a Booster Box (16 packs) of That Time I Got Reincarnated as a Slime Vol.3 pays for itself?
About 45% after ~15% selling fees (53% before fees) as of 2026-10-27, computed from the exact outcome distribution of the That Time I Got Reincarnated as a Slime Vol.3 pack model rather than a simulation.
