A lubricant leakage stop is provided on the shaft of a rotary device in the form of an annular groove in the shaft. In one embodiment the annular groove is formed with an annular inner surface at the bottom of the groove and with an annular intermediate surface positioned between two portions of the annular inner surface. The intermediate surface has a larger diameter dimension than the two inner surface portions on the axially opposite sides of the intermediate surface. The intermediate surface also has a smaller diameter dimension than that of the two portions of the shaft outer surface on axially opposite sides of the groove. In a second embodiment, the annular groove is formed with an annular inner surface that tapers from the bottom of the groove outwardly to the outer surface of the shaft on one side of the groove. Any lubricant leakage axially along the shaft outer surface is stopped by the annular groove and is thrown by rotation of the shaft radially outwardly from the shaft intermediate surface to a lubricant reservoir surrounding the shaft. Each annular groove intersects the shaft outer surface at an annular, chamfered surfaces at one side of the groove. The reduced diameter of the shaft intermediate surface and the annular chamfered surface of the shaft allow component parts of the rotary device to be press fit over the groove without being damaged by the construction of the groove.

Five cards are dealt to each player and to the dealer. Any player having a predetermined automatic winning holding is immediately rewarded and excluded from further participation in the game except to resolve any bonus wager. Each player not having an automatic winning holding has the option to discard and replace a single card. The dealer hand is revealed the dealer receives a single additional card. In turn, each player's hand is revealed. Each base wager is resolved by comparing the poker ranking of the player's hand to the poker ranking of the casino hand. The player is rewarded if the player's hand has a higher ranking than the dealer hand; otherwise, the player's base wager is collected by the casino. Bonus wagers are resolved by comparing the final player hand and the final dealer hand to a predetermined set of bonus holdings including, at least, a bonus holding in which the final player hand includes one joker, a bonus holding in which the final player hand includes two jokers, and a bonus holding in which the final dealer hand and the final player hand each include one joker. son, 273/139; US-6305687, 20011000, Pollock et al., 273/269; US-6390916, 20020500, Brown, 463/017; US-6612576, 20030900, Stancik et al., 273/139
