Abstract:

A method of playing a game on a gaming machine is performed by placing a wager on an underlying wagering game and playing the underlying wagering game according to the rules of the underlying game. When a predetermined event occurs in the underlying game, the player enters at least one bonus game. The bonus game may have at least one event where a) an animated event proceeds to a conclusion and an original bonus that increments or decrements with the proceeding of that animated event, and b) using a sequential set of displays to determine a number of spins to be used in a bonus round and to determine a multiplication factor to be used in spins to be used in the bonus round.

Abstract:

A method of playing a primary game on a gaming machine is performed by placing a wager on an underlying wagering primary game and playing the underlying wagering primary game according to the rules of the underlying primary game. When a predetermined event occurs in the underlying primary game, the player enters at least one secondary game. The secondary game may have at least one event where a) an animated event proceeds to a conclusion and an original bonus that increments or decrements with the proceeding of that animated event, and b) using a sequential set of displays to determine a number of spins to be used in a secondary game and to determine a multiplication factor to be used in spins to be used in the secondary game.

Abstract:

A hose holder boom assembly () includes a first pivotal connector () pivotally mounting an open end () of a first tube () to a sidewall () of a cabinet () about a first pivot axis. A second pivotal connector () mounts an open end () of a second tube () to the other open end () of the first tube () about a second pivot axis parallel to and spaced from the first pivot axis. Movement of the first tube () relative to the sidewall () and relative movement between the first and second tubes () are limited to a pivot plane extending perpendicular to the first and second pivot axes and including the first and second tubes (). The open end () of the second tube () is pivotable at an obtuse angle to each of two sides of the other open end () of the first tube (). A hose () for outputting paving material extends out of the cabinet () and through the first and second tubes () and the first and second pivotal connectors ().

Abstract:

A pavement crack router includes a plurality of bits rotatably mounted to a frame in a direction. A ratchet gear is rotatable with a wheel mounted to the frame. A movable safety release is operably connected to a ratchet rod pivotable between an engaging position engaged with the ratchet gear preventing rotation of the wheel in a reverse direction and a releasing position disengaged from the ratchet gear allowing free rotation of the wheel. An elastomeric inner tube is mounted around a lower end of each of two handle bars and is slideably received in an outer tube fixed to the frame. Two elastomeric washers are mounted around the lower end of each handle bar and sandwich the inner tube within the outer tube. A switch is operable to lower the frame and bits for opening and cleaning a crack in pavement.

Inventors:

Michael C. Halvorson - Las Vegas NV, US

International Classification:

A63F 9/24

US Classification:

463 20

Abstract:

A gaming system, a gaming machine and a method is provided in which the player plays a primary game or a base game on a gaming device. During the play of the primary game or the base game, the player accrues value points. At one or more times, a player participates in a bonus event. The player may apply accrued value points to the bonus round to increase a payout for a winning bonus event result. The bonus event may be triggered randomly or it may be triggered when the player accrues a threshold number of value points. If the bonus event is triggered before the player reaches the threshold value any value points which were not already allocated to the bonus event by the player are lost. The bonus event may comprise an online-related social-networking game.

International Classification:

G07F 17/32
G07F 17/34

Abstract:

A gaming system and method provides a game having a plurality of segment sets, wherein one or more of the plurality of segment sets includes one or more selectable segments. In some implementations, the selectable segments are associated with symbols. In some implementations, gaming system randomly selects at least one segment from one or more of the plurality of segments. The gaming system provides a plurality of different awards depending on the particular combination of symbols associated with the selected segments. In some implementations, when the gaming system selects a plurality of segments associated with different predetermined symbols, the gaming system may determine an award by adding the value of symbols associated with the remaining selected segments.

Abstract:

Systems, methods, and computer-readable storage devices for a gaming system are disclosed. Operations performed by the gaming system include displaying symbols in symbol display areas. The operations also include determining, based on an amount of a wager, an expansion area including two or more symbol display areas. The operations also include determining an expansion symbol from the symbols included in the two or more symbol display areas. The operations also include converting the expansion symbol into a stacked symbol filling the two or more symbol display areas included in the expansion area. The operations also include determining whether the symbols displayed in the symbol display areas, including the expansion symbol, include a winning symbol combination.
