Dig & Clean Islands: 4 Islands, Luck Multipliers and Costs

Update 1 added Sphinx Sands, and Update 2 added Frozen Shores. The Update 1 in-game changelog line “New Island: Sphinx Sands” was double-read in S8 at 0:24 and S7 at 10:49. The observed luck ladder now runs 1× → 2× → 4× → 8×, while the later unlock prices come from one on-screen travel-menu recording and are marked accordingly.

Four-island map after Update 2

Island	Luck	Unlock cost	Evidence status
Home Beach	1×	Starting area	Arrival banner confirmed in two independent recordings (S1 and S2)
Shipwreck Cove	2×	1.1M cash	Luck, 2× gold and cost are retained from our August 8 read; its arrival banner was not shown in any of the six Update 2 recordings we read
Sphinx Sands	4×	32M¢	Arrival banner is a single-recording read (S2); price is a single on-screen source (S6)
Frozen Shores	8×	120M¢	Arrival banner confirmed in three independent recordings (S1, S2 and S4); price is a single on-screen source (S6)

The Home Beach banner read “Home Beach / 1X LUCK” in S1 and S2. The Sphinx Sands banner read “Sphinx Sands / 4X LUCK” in S2. Frozen Shores read “Frozen Shores / 8X LUCK” in S1, S2 and S4.

The S6 menu showed “sphinx sands (32M¢)” and “frozen shores (120M¢)”. Each price is therefore a single-source on-screen read. S4's narrator also said 120M for Frozen Shores; that corroborates the number but is not a second on-screen price read.

Travel-menu evidence and an unresolved name conflict

S2 showed three separate travel menus and was rechecked. The menus excluded the island where the player was standing. From Home Beach, the rows read:

“#1 - shipwreck cove / #2 - sphinx sands / #3 - frozen shores / #4 - bye”

Unresolved travel-menu name: one later recording, S4, showed a different five-row format: “#1 - home beach / #2 - shipwreck cove / #3 - desert dunes [HOME] / #4 - frozen shores / #5 - bye”. That is the same slot where the other recordings show “sphinx sands”, and this version included the current island with a [HOME] tag. The S2 arrival banner clearly reads “Sphinx Sands”, so this guide uses that name. The “desert dunes” row may reflect a rename or a travel-menu rework in a post-update hotfix; the available footage did not resolve which.

The Pyramid is level-gated

On Sphinx Sands, S2 showed a door labeled “PYRAMID”. In that single recording, the Ranger NPC said:

“Not yet! That door only answers to level 25 and higher. Keep digging.”

That makes the Pyramid level-25 content. Levels & XP is listed as an Update 2 feature in the in-game changelog, confirmed in two independent recordings (S2 and S5).

What changed since our August 8 read

Our August 8 version stopped at Home Beach and Shipwreck Cove because the pirate then answered “Ain't charted yet! Check back soon...” when asked about the next island. That was accurate for the footage and date we had. Update 1's in-game changelog lists “New Island: Sphinx Sands”, confirmed by the S8 and S7 reads. Update 2 then added Frozen Shores. The Update 2 on-screen changelog was confirmed in three recordings, S2, S5 and S7, and listed:

• New Content: “New Island: Frozen Shores”, “New Rarity: Anomaly”, “4 New Items”, “15 New Gear Tiers” and “The Pyramid”.
• New Features: “Levels & XP”, “Offline Earnings”, “Gift Passes to Friends”, “Collection Luck Milestones”, “2 New Leaderboards”, QOL, bug fixes and “Codes”.

Current arrival banners and travel menus confirm four islands. The current code list is maintained in the codes guide.

Island versus tool: the same fork at two scales

Early-game fork: 1.1M

Shipwreck Cove and the Black Shovel each cost 1.1M in our August 8 read. That creates a structural choice between an area multiplier and a tool step:

• The island applies its luck multiplier to the gear already owned, and the arrival footage also showed 2× gold.
• The shovel raises the digging-power gate. The August 8 footage showed the message "You need a stronger shovel to dig this!" when the equipped tool was too weak.
• Rarer finds are worth disproportionately more, so the area and tool purchases affect different parts of the loop.

Late-game fork: 120M

The same structure repeats at a higher scale. Frozen Shores costs 120M¢ in the single on-screen price read, while its own gear ladder runs from 32M to 320M. The area side of that fork carries an observed 8× luck payoff; the tool side advances the Frozen Shores gear tracks. Those facts show the shape of the decision, without establishing one purchase order for every loadout.
