How does the museum work in Dig & Clean?

Place cleaned items on your plot's pedestals and tourists pay while you hunt. The August 8 recording showed per-second income cards. The August 19 recording showed discrete tourist-payment popups, a platform with pedestals and a second floor gated by 'Unlock Upstairs 750M¢.' The footage does not establish whether the two income displays changed between versions or coexist.

What should I display in the Dig & Clean museum?

Use available pedestals for your strongest rarity cards and replace a weaker display when a stronger one appears. The dated per-second sample tracked rarity closely, while S7's later tourist-payment events ranged from +4.8M¢ to +623.4M¢ without showing how each payment was calculated.

Do I have to be online for the Dig & Clean museum to earn?

The Update 2 changelog lists 'Offline Earnings,' but across the eight recordings reviewed through August 20 an offline-earnings menu or payout popup was not shown. The August 19 footage does show tourists paying during active play and an anti-idle notice when tourists wander off, so this guide leaves offline mechanics and numbers undescribed.

How much does a museum item earn in Dig & Clean?

The August 8 recording showed cards from 391/s for a 1-in-22 Duck to 3.9K/s for a 1-in-500 Bear. The August 19 recording instead showed 16 lump-sum tourist payments from +4.8M¢ to +623.4M¢. Those are two dated presentations rather than one current universal rate table.

Dig & Clean Museum Guide: Pedestals, Tourist Payments and Upstairs

The museum plot turns cleaned finds into tourist income. Update 1 expanded the plot, and the available recordings show two different income presentations that need to remain dated.

Plot layout and Update 1 expansion

The August 8 footage showed an outdoor wooden pier lined with display stands. The August 19 S7 footage showed the player's plot as a platform with pedestals and a purchase labeled:

“Unlock Upstairs 750M¢”

The Update 1 in-game changelog lists “Second Plot Floor” and “8 New Pedestals”. That changelog wording was double-read in S8 at 0:24 and S7 at 10:49. The 750M¢ price is a single-recording purchase-UI read from S7.

To use the plot, carry a cleaned item to an available pedestal. Earlier footage showed the item placed on the stand and an income card appearing.

Pedestal purchase evidence

S7 repeatedly showed purchase prompts labeled “Buy Pedestal 10” with escalating prices as the recording revisited the plot:

S7 timestamp	Prices visible
09:21–09:27	5B · 12.5B · 27.5B
15:26	25B · 75B
17:24	185B · 450B

The footage makes an escalating ladder clear. Because one recording visited the plot at different times and the visible values include 27.5B before a later 25B read, it does not pin down one exact order or complete sequence. Treat these as observed prices, rather than an ordered price table.

Income evidence: August 8 per-second cards

The August 8 recording showed display cards with a green income figure and /s. The readable sample was:

Display	Rarity	Income
Duck [2KG], OK	1 in 22	391/s
Bear [4.2KG], Great	1 in 80	965/s
Bear [3.3KG], Good	1 in 244	1.1K/s
Sunglasses [0.1KG], MINT	1 in 147	1.4K/s
Bear [11.1KG], Perfect	1 in 500	3.9K/s

Four of those five rates tracked close to the same 45 × odds^0.7 coefficient as sale values; the Good Bear was the visible outlier. The full comparison is on the item-values page.

The same dated source set also showed a Frozen Mammoth at 1 in 17,579,022 and an Old Tank at 1 in 9,574,469, with income popups of +493.7K and +458.1K.

Income evidence: August 19 tourist payments

S7 showed income arriving as discrete tourist payment events: 16 +X¢ popups were observed, ranging from +4.8M¢ at 11:21 to +623.4M¢ at 13:57. A per-second tick rate was not shown in that recording.

This later footage should not erase the earlier cards. The reviewed evidence does not establish whether Update 1's plot rework changed the income mechanic or whether per-second cards and lump-sum tourist payments coexist. The honest current description is therefore:

August 8 showed per-second display cards; August 19 showed lump-sum tourist payments. The relationship between those presentations remains unresolved in the footage reviewed through August 20.

Tourists and active-play notice

The older sign at the entrance read:

“Tourists come while you're HUNTING for treasure!”

S7 supplied a matching active-play warning at 11:06:

“Notice: Tourists are wandering off! Go find treasure to bring them back!”

The popup included an OK button. Together, those screens are consistent with tourists paying while the player goes out to find treasure. They do not, by themselves, define an idle timer or offline payout formula.

How to manage available pedestals

The footage supports three practical rules:

Clean before deciding. Rarity and condition appear on the cleaned card.
Use open space. A placed item generated income in each dated museum presentation.
Replace weaker cards over time. The formula evidence makes rarity odds the strongest value predictor in the accepted sample; sell surplus when immediate cash is needed.

Weight was a weaker predictor in the small August 8 sample: the 0.1KG Sunglasses showed 1.4K/s, above the 4.2KG Bear at 965/s, while the Sunglasses also had the larger rarity-odds number. That is a sample result, rather than a universal weight rule.

Offline earnings evidence boundary

“Offline Earnings” is listed in the Update 2 changelog, now seen in S2, S5 and S7. Across the eight recordings reviewed through August 20, an offline earnings menu, payout popup, rate or cap was not shown. The feature is changelog-confirmed; its mechanics and numbers remain outside the available on-screen evidence.

Selling still supplies immediate cash

The Sell booth gives immediate cash for inventory. The museum evidence is version-dated and pays over time or through tourist events, while selling supplies liquidity for gear, island unlocks and plot expansion. Use the money guide for those spending forks.
