1. A random number selector for games comprising:
- (a) a memory having an addressable storage location for each number in a game;
(b) means to sequentially address each said storage location;
(c) random selection means to selectively record a pick at a storage location when it is addressed and including means for picking a number;
(d) first clock means operating at a first cyclical rate for clocking said means to sequentially address through each said storage location;
(e) gate means for blocking said clocking;
(f) second clock means operating at a second cyclical rate connected to enable said gate means at the beginning of each cycle of said second cyclical rate;
(g) disabling means connected from said memory for disabling said gate after each unpicked number location in said memory has been addressed, the frequency of said first cyclical rate being greater than the frequency of said second cyclical rate by at least the number of said addressable storage locations whereby unpicked number locations are addressed consistently at said second cyclical rate irrespective of the sequential addressing of already picked number locations.

Abstract
A bingo computer in which every number has a storage location in an addressable memory and a "pick" counter sequentially addresses the memory at a high rate of speed for locations picked and a much lower rate for locations not picked. A display counter shares the memory.

8. A method of sequencing selections through a fixed number of digital storage locations in which picked selections are deleted from further selection without loss of randomness comprising:
-
(a) addressing said digital storage locations by a counter; (b) sequencing said counter at a first clock rate when the locations addressed have not been previously selected; (c) sequencing said counter at a second clock rate faster than said first clock rate by enough to address every location of said digital storage locations during a single cycle at said first clock rate when the location addressed have been previously selected; and
,(d) inhibiting selection when said counter addresses locations previously selected.
