1 Chip Economy

The Mandalay Bay uses a unified chip wallet shared across every activity.

1.1 Core concepts

Concept	Description
Chip	Single currency unit ($1 = 1 chip)
Wallet	Your balance everywhere on the floor
Ledger	Audit trail of every transaction
Buy-in	Purchase chips at the Cashier (not gambling)
Cash-out	Remove chips from your wallet at the Cashier

1.2 How wagers work

    participant Player
    participant Wallet
    participant Activity

    Player->>Activity: Place wager
    Activity->>Wallet: debit(amount)
    Note over Wallet: Balance reduced immediately
    Activity->>Activity: Resolve outcome
    alt Win
        Activity->>Wallet: credit(payout)
    else Push
        Activity->>Wallet: credit(stake)
    end

1.2.1 By activity

Activity	When chips move
Blackjack	Bet deducted at hand start; settlement applied after each hand; wallet synced to table rail
Slots	Debited per spin; wins credited immediately
Sports Book	Debited when ticket placed; credited on settlement (or push refund)
Cashier	Buy-in credits; cash-out debits

1.3 Transaction ledger

Every operation creates a ledger entry:

14:32:01 | blackjack    | -50  | bal 950  | Hand result
14:32:45 | blackjack    | +100 | bal 1050 | Hand result
14:35:10 | slots        | -25  | bal 1025 | Slot spin $25
14:35:10 | slots        | +50  | bal 1075 | Two cherries! 2x
14:40:00 | cashier      | +500 | bal 1575 | Purchased $500 in chips

View the last 20 entries at Cashier → View transaction ledger.

1.4 Transaction types

Type	Meaning
`buy_in`	Cashier purchase
`cash_out`	Cashier withdrawal
`wager`	Bet placed or net loss recorded
`win`	Payout credited

1.5 Player Stats vs ledger

Player Stats — aggregated net per activity (visits, bets, net winnings)
Session net — sum of all gambling transactions (excludes buy-ins and cash-outs)
Ledger — line-by-line audit trail

1.6 Blackjack wallet sync

Blackjack maintains a table rail (in-hand balance) that mirrors your wallet:

On sit-down: rail = wallet balance
After each hand: wallet adjusted by net hand result
On stand-up: final reconciliation ensures wallet = rail

This prevents desync between the table and the casino floor.

1.7 Off-strip bank account

Park winnings outside the cage. From Private Offshore Account:

Deposit outside funds
Life & business expenses — personal lifestyle, legal/debt, business contracts, misc
Buy resort privileges — floor floats, comps, arcade vouchers, late-checkout credit, VIP/High Limit markers, recovery spa
Rename account / view bank ledger

Spends respect MGM Rewards tier withdraw caps.

1.8 Insufficient funds

Activities check balance before accepting wagers:

Cannot spin slots below machine minimum
Cannot sit at blackjack below table minimum
Cannot place sports wagers below $10 or above balance
Cashier cash-out disabled at $0 balance

Visit the Cashier to buy more chips when low.
