Cash Income Tier List

Offline Cash is the engine of Merge a Black Hole. XAF Games designed progression so merges unlock stronger income generators, rebirth multipliers amplify returns, and base lock protects earnings while you are away. This cash income tier list ranks black holes purely on money — not raid flashiness — so farmers know exactly which merges to chase before the next Sunday update reshuffles stats.

Pair this page with the tier list hub for overall rankings and the raiding tier list only if you split time between farming and PvP.

Early meta disclaimer

Income rankings are early-meta and volatile. A hole buffed on Sunday can jump two tiers overnight; nerfed S-tier farmers may fall to B-tier. We update after patch notes on the updates tracker. Until rankings stabilize Tuesday–Wednesday post-patch, hold duplicate mid-tier income holes instead of merging them into uncertain chains.

Ranking criteria

Offline Cash per hour — Primary metric at equal upgrade investment.

Merge cost efficiency — Cash spent per income gained merging from previous tier.

Rebirth scaling — How multipliers affect long-term ROI after reset cycles from the getting started guide.

Star Shop boosts — Some holes gain extra from Star purchases; factor FREESTARS Stars from the codes hub into planning.

Board space — Large income holes that block merge grids rank slightly lower unless income compensates.

Cash income tier table

Tier	Black holes	Offline Cash profile
S	Gravity Well MK-II, Quasar Harvester, Void Collapse	Top offline Cash; worth Star upgrades
A	Accretion Drake, Nebula Siphon, Pulse Ring+	Strong farmers; merge before rebirth
B	Cash Comet, Neutron Maw, Twin Orbit	Mid-game bridges — merge through
C	Starter Abyss, Mini Vortex, Dust Hole	Early tutorial income — exit fast
D	Broken Shard, Glitch Remnant	Nerfed event holes — sell or merge up
F	Scrap Singularity	Misleading tooltip — worst Cash/million merge cost

Tilde (~) marks holes under observation when a single Sunday patch moved them more than one tier.

S-tier income deep dive

Gravity Well MK-II — Current offline king for pure farmers. Merge cost is steep, but hourly Cash beats rivals until rebirth three. Invest MERGE code Cash from working codes toward this chain after tutorial. Lock base before logging off — raiders target obvious Gravity Well bases.

Quasar Harvester — Slightly lower peak Cash than Gravity Well but cheaper merge path — better for players who rebirth early and restart income loops. Synergizes with auto merge stop-at-tier settings.

Void Collapse — Hybrid that still earns S-tier Cash while contributing raid value. Choose when you refuse to maintain separate income and PvP inventories; see overall tier list for tradeoffs.

A-tier: best value before first rebirth

Accretion Drake — Recommended first “big merge” target after redeeming codes via how to redeem. Income respectable through rebirth one.

Nebula Siphon — Excels when Star Shop income boosts active — spend FREESTARS carefully here if shop rotation includes Siphon modifiers.

Pulse Ring+ — Enhanced variant from recent Sunday content; verify you merged the plus variant, not base Pulse Ring (B-tier).

B-tier and below

Cash Comet — Meme name, real mid-game stepping stone. Do not Star upgrade.

Neutron Maw / Twin Orbit — Acceptable if patch notes accidentally buff before wiki update — re-test locally.

C-tier — Exists to teach loops in the merge guide. Speed merges using offline Cash claims.

D/F — Deprecated farmers from expired events listed on expired codes timelines. Merge out immediately.

Optimal income progression route

1. Redeem MERGE and FREESTARS on the codes page.
2. Merge through C-tier into Accretion Drake (A-tier).
3. Farm offline Cash with base locked; claim on login.
4. Push into Gravity Well MK-II or Quasar Harvester depending on rebirth plans.
5. Rebirth when merge cost of next S-tier exceeds 48 hours of offline gain at current tier — recalculate after Sunday patches.
6. Repeat with Star Shop boosts prioritized for income, not cosmetics.

Offline Cash mechanics reminder

Income accrues while offline up to a cap tied to your best active income holes at logout. Swapping farmers without locking invites raids that reset hours of accrual display — you keep unclaimed Cash only if holes survive. Auto lock from the scripts hub helps habitual forgetters.

Claim prompts sometimes bug after updates — if numbers look wrong, rejoin once before panicking; note patch ID on updates.

Stars and codes for income players

MERGE — 1,000 Cash jump-starts Drake or Well merge components.

FREESTARS — 2 Stars toward income boosts in Star Shop rotations.

Never buy raid-only holes with farmer Stars — consult raiding tiers only for alt loadouts.

Automation for income

Auto merge scripts should whitelist income S-tier caps. Keyless scripts with reckless merge-all settings destroy Quasar chains — configure reserves. Manual play remains safest on patch Sundays.

When income tiers change

Watch for these Sunday patch signals:

• “Global offline Cash multiplier adjusted”
• Specific hole name in nerf/buff section
• Rebirth cost changes shifting ROI math
• New hole introduction with “harvester” or “well” keywords

Update personal merge plans before mass-merging stockpiled duplicates.
