Abstract
The present invention includes an apparatus and method for a bonus game, and particularly a free spin bonus with an incrementing multiplier. The bonus game includes a plurality of reels having a plurality of symbols and multipliers. The gaming device provides a number of free spins to the player at the beginning of the bonus game. The multiplier preferably starts at “1×” and increases by one after each free spin. Initially, the player spins the reels attempting to obtain a winning symbol combination on the reels. If the player obtains a winning combination, the gaming device provides an award. The award is multiplied by the multiplier and the player receives the multiplied award for that free spin. The player continues to spin the reels until there are no free spins remaining in the bonus game.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
