Abstract: A game device allows a player to play chance-based games and skill-based games. A skill-based game is provided as an initial game, with a chance-based game being provided subsequent to the skill-based game. The chance-based game gives the player a chance to win prizes, and whether a prize is won and the value of prizes are determined by the outcome of the chance-based game.

Abstract: A method of implementing desired odds for a reel-type slot machine is disclosed. All of the possible reel stop combinations are assigned to unique terminal nodes in one or more fractional branching trees stored in a ROM. The tree(s) comprises a main tier, a plurality of lower tiers and a plurality of terminal nodes. Each of the tiers has a number of entries which lead either to a lower tier or to a terminal node. A random number generator is used to select entries on each tier until a terminal node is selected. The reel stop combination or a particular symbol assigned to the terminal node is then displayed on the pay line and an award is paid based on a pay table.
