The Blank Voucher does nothing when you buy it. No Chips, no Mult, no extra slot. The game is being literal.
Blank matters because it unlocks Antimatter, the upgraded voucher that adds +1 Joker slot. Redeem Blank 10 times across standard unseeded runs and Antimatter becomes eligible to appear in later runs.

Why does Blank exist if it does nothing?
Blank is the price of putting Antimatter into your collection. The first ten purchases trade $10 in the current run for permanent account progress. Once the unlock is complete, Antimatter can show up as Blank's upgrade in future runs.
That makes Blank a strange shop decision. It is bad for the hand in front of you, but useful for the profile you will keep playing. If that $10 is the difference between buying a scoring Joker and dying to the next Blind, skip Blank. The counter can wait.
How to unlock Antimatter
- Play a standard unseeded run. Seeded and Challenge runs do not advance this unlock.
- Redeem Blank when the shop offers it. In normal play, Blank is a one-per-run purchase.
- Repeat until the total reaches 10. The count carries between eligible runs, so you do not need ten purchases in one game.
- Start another run and buy Blank again. Antimatter is its upgrade. Unlocking it does not remove the current-run prerequisite.
- Keep checking later voucher shops. Antimatter is now in the pool, not guaranteed in the next shop.
The ten Blank purchases cost $100 in total, spread across multiple runs. There is no prize for rushing it. Buy when the run can spare the money.
Unlocking Antimatter vs finding it in a run
These are separate steps, and most confusion comes from mixing them together.
| State | What it means |
|---|---|
| Fewer than 10 valid Blank purchases | Antimatter is still locked. |
| 10 valid purchases completed | Antimatter is permanently unlocked. |
| Antimatter unlocked, but Blank not bought this run | Its upgrade cannot appear yet. |
| Blank bought this run | Antimatter can appear in a later voucher shop. |
| Blank bought, Antimatter still missing | Normal shop luck. The unlock is working; the result is not guaranteed. |
Should you buy Blank?
| Situation | Call |
|---|---|
| Antimatter is still locked, money is comfortable | Buy. The progress stays on your profile. |
| Antimatter is still locked, next Blind looks dangerous | Skip. Staying alive matters more than one unlock tick. |
| Antimatter is unlocked and the build wants another Joker | Buy if you can afford to chase the upgrade. |
| Antimatter is unlocked and the run is nearly over | Usually skip. You may not see enough voucher shops to benefit. |
| You are in a seeded or Challenge run | Skip for unlock purposes; the purchase will not advance the count. |
What the extra Joker slot changes
Antimatter raises the normal Joker limit from five to six for the rest of the run. The extra slot can hold another scoring Joker, economy piece or utility effect without forcing an immediate sale.
It also gives flexible builds more breathing room. Blueprint and Brainstorm have another possible partner, Showman has space for duplicates, and Riff-raff is less likely to fill every open slot. Antimatter does not guarantee a winning build, but few vouchers open more options.
Joker Stencil rewards empty Joker slots. Antimatter gives the build one more slot to use or leave open.
Common questions
No. There is no hidden Chips, Mult or shop modifier. Its value is the Antimatter unlock and, after that, access to Blank's upgrade path.
No. The tenth valid purchase unlocks Antimatter for future voucher pools. It does not force Antimatter into the next shop.
No. Challenge runs do not advance the unlock. Seeded runs do not count either; use standard unseeded runs.
Only when you want a chance at Antimatter in that run. The upgrade cannot appear before its base voucher has been redeemed.
