Casino hold

Casino hold is the percentage of chips or money sold that a casino keeps over a given period or game session.

Formula
hold = chips kept ÷ chips sold12
Example
If a casino keeps $300 from $1,000 in chips sold, the hold is 30%.1
Can exceed 100%
Hold can exceed 100% if chips bought at another table are carried in and lost at the table being measured.1

Key points

  • For table games, hold is measured from the casino’s drop versus the chips players bought for that table or period.12
  • If players lose all purchased chips, hold is 100%.1
  • In electronic games, “hold” can mean the game’s theoretical return rather than a chip-retention ratio.3

How long can a casino hold your money?

The term “casino hold” does not refer to time. It measures the percentage of chips sold that the casino keeps, not how long it holds funds.
