Scouted target selection
Vault targets — gross finale pool
- A player's first hosted heist always has Cash. This is a separate first-run state, not a percentage for later repeats.
- On repeats, Vault Contents randomly reveals Cash, Artwork or Gold. Rockstar does not publish current permanent weights, so the table does not invent a percentage split.
- Diamonds are 0% outside an enabled event. When Rockstar enables them, availability and any weight follow that event's rules—the guide does not hard-code a current probability.
- The host's per-activity state determines first-weekly finale eligibility; the increase covers every player. Unofficial partner rates are labelled separately in the model.
| Payout target | First hosted run | Repeats — Vault Contents | Event status |
|---|---|---|---|
| Cash | 100% | Random — unpublished weight | Permanent repeat pool |
| Artwork | Unavailable | Random — unpublished weight | Permanent repeat pool |
| Gold | Unavailable | Random — unpublished weight | Permanent repeat pool |
| Diamonds — event only | Unavailable | 0% outside an enabled event | Weight defined by the Rockstar event |
An unknown repeat weight is not zero: the result remains random, but Rockstar does not publish a permanent percentage split.
| Payout target | Repeat — Normal | Repeat — Hard | First weekly — Normal | First weekly — Hard |
|---|---|---|---|---|
| Cash | $1,480,500 | $1,628,550 | $2,753,730 | $3,029,103 |
| Artwork | $1,645,000 | $1,809,500 | $3,059,700 | $3,365,670 |
| Gold | $1,809,500 | $1,990,450 | $3,365,670 | $3,702,237 |
| Diamonds — event only | $2,303,000 | $2,533,300 | $4,283,580 | $4,711,938 |
Diamonds are an event-gated target, not a permanent rotation entry. Player cuts and NPC fees are settled separately.

Complete step-by-step operation
OPERATIONS GUIDE V2 • DUO
Scope the casino and vault contents, choose one of three approaches, prepare the matching equipment and lead the crew from entry to the buyer handoff.
Start here
- After meeting Lester at Mirror Park, buy an Arcade through Maze Bank Foreclosures and complete its setup.
Go to the underground planning area and launch casino scope-out from the first of the three boards.
The basement of your Arcade.
The three Diamond Casino Heist planning boards.
- The Master Control Terminal, extra cabinets and private Arcade rooms are not required for the heist.
First run and replay
These are two persistent story instructions. They are not the finance calculator's weekly-variant switch.
First story playthrough
The first cycle requires Arcade setup, a full Scope Out Casino and discovery of entrances; identified access points remain recorded.
Story replay
On replay, scope the new Vault Contents and choose an approach other than the most recently used one; permanent access points do not need to be photographed again.

finale The Diamond Casino Heist
Enter with the selected method, clear the vault and deliver the surviving take to the buyer.
Strategies that genuinely change the route
Silent & Sneaky
- When
- When stealth equipment is ready and the crew knows cameras and patrols.
- Plan
- Keep the alarm off from entry, synchronize dual readers and leave the vault before the gas.
- Trade-off
- A clean entry reduces exit pressure, but one unsynchronized takedown can break the plan.
The Big Con
- When
- When the selected entry and exit disguises have been prepared.
- Plan
- Do not draw weapons before the vault; after collecting the target, move together to the prepared exit disguise.
- Trade-off
- The easiest vault access depends on preserving cover and following the correct route.
Aggressive
- When
- When breach gear, weapons and, if needed, Duggan Shipments are complete.
- Plan
- Push as one front, preserve armor for the retreat and loot only after the chamber is secure.
- Trade-off
- The alarm is part of the approach, so disorder costs health, vault time and retained take.
Plan for the selected team: DUO
Selected in the calculator • DUO for “The Diamond Casino Heist — complete flow”: Player A: Approach lead + Loot collector; Player B: Vault hacker + Escape lead.
Concrete roles
Maintains the selected entry rules and regroups the crew before the vault level. Assigns carts or artwork and ends collection before the gas.
Handles terminals and calls the retreat against the hired hacker's time. Leads the move to disguises or vehicles, loses police and reaches the buyer.
Actions, risk and run recovery
- 01
unlockArcade and planning board - Action
- The host buys an Arcade, completes its setup and launches the heist from the underground planning area; progress is tracked across its three boards.
- Tip
- Finish the Arcade setup before hiring support crew.
- Risk / failure condition
- Inactive boards block scope-out and approach selection.
- How to recover the run
- Complete the setup mission and return to the basement.
- 02
prep / preparationScope Out Casino - Action
- Photograph the main entrance and discover extra access points such as the roof, terrace, security tunnel, sewer and rear doors. Discovered access points remain available on later runs.
- Tip
- Photograph the entrances, exits and security features that fit the plan.
- Risk / failure condition
- An unscoped point will not appear as a finale option.
- How to recover the run
- Return to Scope Out Casino and send Lester the missing photograph.
- 03
prep / preparationVault Contents - Action
- Gain access to the casino camera network and identify the current vault contents. This scope mission reveals the target and unlocks approach selection.
- Tip
- Identify the vault contents before choosing the hacker and collection plan.
- Risk / failure condition
- A collection plan mismatched to the target wastes vault time.
- How to recover the run
- Repeat the Vault Contents camera check and assign positions for the identified target.
- 04
prep / preparationChoose an approach - Action
- Choose Silent & Sneaky, The Big Con or Aggressive. The approach determines entry, required gear, disguises and the vault-breach method; the most recently used method cannot be selected immediately again.
- Tip
- Lock Silent & Sneaky, Big Con or Aggressive as one coherent route.
- Risk / failure condition
- Mixing entrances and equipment from different approaches breaks the preparation plan.
- How to recover the run
- Return to the second board and align entry, exit and equipment to one approach.
- 05
prep / preparationSupport crew - Action
- Hire a gunman, driver and hacker. The gunman determines weapon sets, the driver getaway cars and the hacker vault time; stronger crew members take a larger cut.
- Tip
- Match the hacker to vault time and the driver and gunman to the chosen escape.
- Risk / failure condition
- A mismatched crew shortens the loot window or supplies unsuitable vehicles and weapons.
- How to recover the run
- Before confirming, revise each specialist so their contribution matches the finale plan.
- 06
prep / preparationMandatory preparations - Action
- Acquire unmarked weapons, getaway vehicles, the hacking device, vault keycards and the approach-specific equipment—such as disguises and drills, stealth hardware or explosive breach gear.
- Tip
- Complete every mandatory board row before launching the finale.
- Risk / failure condition
- Missing weapons, vehicles or the hacking device keeps the finale locked.
- How to recover the run
- Open the missing row, finish the prep and check the third board again.
- 07
prep / preparationOptional preparations - Action
- Prioritize Level 2 Security Passes. Patrol Routes and Security Intel improve awareness, Duggan Shipments weakens guards, and exit disguises help the Big Con crew leave the casino.
- Tip
- Complete Level 2 Security Passes and consider Duggan Shipments and exit disguises for the selected route.
- Risk / failure condition
- A skipped optional prep can add a difficult hack, armored guards or a harder exit.
- How to recover the run
- Do not launch; complete the exact prep that removes the chosen approach's weakness.
- 08
finaleEntry and security level - Action
- In the finale, follow the selected entrance and approach rules: avoid cameras in stealth, preserve the disguise in Big Con or fight inward on Aggressive. Regroup before descending to the vault.
- Tip
- One player leads and restates the approach rule before each security zone.
- Risk / failure condition
- Drawn weapons in Big Con or an unsynchronized stealth takedown triggers the alarm before the vault.
- How to recover the run
- Regroup behind the last cover and continue as one push only if the approach remains viable.
- 09
finaleVault corridor - Action
- Use the keycards simultaneously at the dual reader and complete the required hacks or door breach. Players who are not hacking should immediately position at the carts or artwork.
- Tip
- Count down dual-reader interactions and activate both stations together.
- Risk / failure condition
- A split crew leaves one player exposed in the vault corridor.
- How to recover the run
- Bring both pairs back to the shared door, clear the corridor and retry on a single call.
- 10
finaleCollect the target - Action
- Once the vault opens, divide the loot positions, open locked sections and collect only while enough exit time remains. Leave the chamber before the gas fully activates.
- Tip
- Assign carts or artwork and stop collecting on the hacker's call.
- Risk / failure condition
- Staying at the final position after gas starts costs health and retained take.
- How to recover the run
- Abandon unfinished loot, regroup at the door and begin a shared retreat.
- 11
finaleExit and buyer - Action
- Return by the selected route, use the prepared disguise or covering fire, reach the getaway vehicles, lose the police and only then deliver the remaining take to the chosen buyer.
- Tip
- The escape lead takes everyone to disguises or vehicles before heading to the buyer.
- Risk / failure condition
- Splitting vehicles or approaching the buyer while wanted exposes the full take.
- How to recover the run
- Divert to the shared hiding route, lose the police and resume the delivery as one convoy.
Common mistakes
Mismatched approach
- Consequence
- A wrong hacker, entrance or missing Level 2 Security Passes cuts vault time or breaks the route before the finale.
- Correction
- Return to the approach board, complete the missing prep and reassign entry, exit and disguises.
Broken stealth or cover
- Consequence
- Premature weapons, a camera or an unsynchronized reader triggers resistance early and costs looting time.
- Correction
- If the approach remains viable, regroup behind cover and push as one front; otherwise restart before entering the vault.
Late vault retreat
- Consequence
- Staying for the last cart exposes the crew and reduces retained take on exit.
- Correction
- Abandon the unfinished position, regroup on the exit route and use the prepared disguise or shared covering fire.
Pre-launch checklist
Approach, entry, exit and hacker are agreed before the finale.
Everyone knows their reader, loot position and retreat call.
Lock the approach before hiring support and prepare its exact equipment.
At readers and cameras, one player calls timing while everyone else waits for the synchronized interaction.
The hacker calls the last safe moment and collectors leave before gas fills the chamber.

Expanded informational overview
Guide scopeThis section organizes the complete cycle: requirements, phases, figures and dependencies. The detailed operation flow is in the walkthrough above.
Silent & Sneaky, The Big Con and Aggressive change preparation scope, NPC crew cost and risk profile. The walkthrough maps preparations, roles and decision order for each variant.
04
How the full cycle works
This section complements the walkthrough with full-cycle dependencies: unlock, preparations, finale, settlement and the next available attempt.
Unlock
Base requirement: Arcade. Minimum entry cost is kept separate from the setup fee.
Plan configuration
Available approach, target, difficulty and team choices determine later costs and payout distribution.
Preparations
The model's full time includes required preparation; optional items trade extra time for a safer run.
Finale
The result depends on target or pool value, participant count, possible losses and bonus conditions.
Settlement and replay
After deductions, the pool is distributed using the payout model. Group heists have a 48 min wait after the finale.
05
What affects the result
The min–typical–max range accounts for a variable target, loot or difficulty where applicable.
The setup fee is deducted before the net result is calculated.
Player count and NPC crew fees can change the host and each partner's payout.
The model compares 1 hr 10 min / 1 hr 35 min / 2 hrs 25 min, not the finale alone.
Main strengths
- High payout per completed cycle.
- Clear split between preparation, finale and settlement.
Constraints
- Entry and setup costs reduce the first return.
- The result depends on team size, cuts and cooldown.
