A fill slip is the casino record used when chips are added from the cage or chip bank to a live table game. It identifies the table, amount, denomination mix, and transaction so the chips entering the table can be reconciled later against inventory, drop, and accounting records.
Plain Talk
A fill slip is the receipt for chips going into a table.
When a table needs more chips, the casino does not simply let somebody walk over with a tray and drop chips into the rack. The movement needs a record. That record is the fill slip, or in some modern systems, the electronic version of the same control.
| Term | Plain-English meaning | Where it appears | Why it matters |
|---|---|---|---|
| Fill slip | Record for chips added to a table | Pit, cage, table, accounting | Proves why table inventory increased |
| Fill | The chip movement itself | Cage to table | Keeps the table supplied |
| Credit slip | Record for chips removed from a table | Table to cage | Proves why table inventory decreased |
| Table inventory | Chips assigned to the table | Table opening and closing | Used to calculate table result |

Where You See It
Players may hear a supervisor say a table needs a fill, but they usually do not study the slip. Staff see fill slips in pit procedures, cage records, table-game accounting, and audit review.
Public control standards show why the record matters. Nevada’s table-game internal control standards refer to reconciliation of fill and credit slips, New Jersey’s gaming operation accounting controls include fill-slip procedures, and federal table-game standards treat fill and credit procedures as part of internal control.
Why It Matters
A fill slip matters because it separates casino-supplied chips from chips won from players. Without that distinction, the table’s result can be wrong.
If a table receives $5,000 in chips and nobody records it, the closing inventory may look higher than it should. That can distort table win, confuse audits, and create disputes between the pit, cage, and accounting office.
Example
A baccarat table is short of $100 chips during a busy evening. The supervisor requests a fill for a specific amount and denomination mix. A fill slip records the request and supports the movement.
Once the chips are verified and added to the tray, the table has more inventory than before. Later, when the shift closes, accounting uses the fill record to understand why the table had those extra chips.
From the Casino Side:
From the casino side, the fill slip is not just paperwork. It is evidence of custody.
It connects the cage, the table, the pit, and the accounting department. It helps answer four basic questions: which table received chips, how much value was added, what denominations were included, and whether the records match later review.
A clean fill slip reduces arguments. A bad fill slip creates a problem that may not show up until the table is reconciled.
Common Misunderstanding
Players sometimes think the fill slip is about the current players at the table. It is not. It is about chip inventory.
Another common misunderstanding is assuming the slip proves the table has been losing. It does not. The table may need a fill because of winning players, cash buy-ins, denomination shortages, or normal floor balancing.
Hard Truth
The fill slip is boring paper until the table total is wrong. Then it becomes the first thing everyone wants to see.

FAQ
Is a fill slip the same as a fill?
No. The fill is the chip movement. The fill slip is the record that documents the movement.
What information is usually on a fill slip?
At a high level, it identifies the table, amount, denominations, date or time, and transaction approval or verification details. Exact formats vary by casino and jurisdiction.
Does a fill slip affect a player’s payout?
No. It does not change game rules or payouts. It affects table inventory and accounting.
Why are fill slips reconciled later?
Because the casino must confirm that the chips recorded as leaving the cage match the chips recorded as arriving at the table.
Can fill slips be electronic?
Yes. Some casinos use computerized systems, but the control idea remains the same: document the chip movement clearly enough for later reconciliation.
Deeper Insight
The fill slip sits inside a larger control chain. A table can be busy, noisy, and fast, but the accounting behind it has to be exact. The fill slip gives the casino a reference point when closing inventory and drop are compared against expected values.
This is why fill slips are connected to Table Opening, Table Closing, Drop Box, and Count Room. They are small records inside a bigger system.
Formula / Calculation
| Metric | Formula | Plain-English meaning |
|---|---|---|
| Inventory after fill | Previous Inventory + Fill Amount | The table should hold more chips after the fill |
| Simplified table win | Closing Inventory + Credits + Drop - Opening Inventory - Fills | Fill slips explain why supplied chips are not counted as win |
| Fill variance check | Recorded Fill Amount - Verified Fill Amount | Any difference that needs review |
Formula Explanation in Plain English
A fill slip supports the subtraction side of the table-win calculation. Chips added through a fill came from the casino’s cage. They are not player losses. The slip helps accounting remove that supplied value from the profit calculation.
