20080318652Texas Holdem Peek-A-Boo Poker - Embodiments described herein are directed to an electronic version of Texas holdem poker that adds peek cards from which the private hole cards can be selected. A player makes a wager for a hand or hands to be dealt. Three cards are dealt to the flop. Another three cards are “peek” cards. These three peek cards expose the identity/suit/denomination of the card by illustrating a fold of the top right corner. These cards are placed in respective peek 1, peek 2, and peek 3 spots of the playing area. Random cards are located to the left and right of the peek cards. Considering the flop, the player decides which of the cards he needs to make the best hands. If any of the peek cards are undesirable, a random card or cards are selected from the deck. The two cards the player picks are called the hole cards. Once the two hole cards are picked the turn and river cards are dealt. The player is awarded for the best possible five card hand out of the seven cards. When multiple hands are played, a wide variety of different winning hands can occur.12-25-2008
20080318653Domino Tower Electronic Video Game - Embodiments described herein are directed to an electronic version of domino that adds elements of wagering. A player makes a wager for dominoes to be dealt. A minimum of one domino through a maximum of five dominoes can be wagered on and dealt. Once the dominoes are dealt, the player may “flip” the dominoes by touching them. A player can flip the dominoes online in the starting row, so that dominoes dealt in the next row/level have the best chance of creating a chain. Once satisfied with the dominoes, the player keeps the dominoes to play them. A new row of dominoes is then dealt. Any number of pips on these dominoes that match the bottom dominoes number of pips awards the player a payout and another domino or set of dominoes is dealt to the next row/level. This sequence of play continues until there are no more matching dominoes or the player has hit the maximum payout level. Payouts increase with the size of the domino chain. There is also a bonus game that is awarded whenever a certain type of domino is dealt.12-25-2008
