FRACTIONAL BRANCHING REEL-TYPE SLOT MACHINE

摘要

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.
