How to play it
In our own words, from our seed check (the original post has the finder's own notes).
- Ante 1: the poster buys almost nothing and saves money for Ante 2.
- Ante 2: Brainstorm is card 2 in the shop queue, so it is on display in the first Ante 2 shop.
- Negative Blueprint is card 6 in the Ante 2 queue. Reach it in a later Ante 2 shop or by rerolling. Because it's Negative, it doesn't take a Joker slot.
- Ante 5: the Buffoon Pack in the first shop has another Blueprint.
The poster's plan: The poster rerolls a lot through Antes 3 and 4 and uses Ankh and Showman to get more Blueprint and Brainstorm copies. We only checked the three cards above.
Route: Antes 1-8

What the post claimed
The original poster says this seed has Blueprint and Brainstorm, mentioning Ante 5.
- Blueprint: Checked.
- Negative Blueprint - Ante 2 shop card 6 (later shop or reroll) (Ante 2)
- Blueprint - Buffoon Pack in the Ante 5 shop before the Small Blind (Ante 5)
- Brainstorm: Checked.
- Brainstorm - Ante 2 shop card 2 (on display in the first shop) (Ante 2)
Caveats
- The post didn't name a deck, so we checked Red Deck.
- The post didn't name a stake, so we checked White Stake.
- 7-character code; our check still reproduces the claim.
- Skipping a blind also skips the shop after it, so later shops change if you skip or reroll differently.
- Seeded runs don't count toward unlocks or achievements.
How this seed was checked
This run was verified by BalatroBuddy on v1.0.1 (checked 2026-10-28) on Red Deck at White Stake.
Run Settings Note: The original community post did not specify the deck or stake. BalatroBuddy checked and verified these seed mechanics using Red Deck and White Stake.
What was verified: Shop contents, pack offerings, skip tags, and boss blinds for Antes 1-8.
Nobody at BalatroBuddy has played these seeds yet: every route here is worked out from the game's seed logic, not a human playtest.
We work out Antes 1-8 for the posted deck and stake from the game's seed logic. A seed is verified when every item in the post title shows up in a pack, a voucher or the first few shop cards. We leave playing-card ranks in Standard Packs off, because we can't confirm them reliably. Results assume every Joker is unlocked.
