Abstract

In amusement and game apparatus of the type having a set of symbol-bearing reels and mechanism for spinning the reels after depositing the proper coins, an electronic control for selecting the stopping positions for the reels, for detection of the reel position, for calculating the payout to the player in response to the reel position, and for monitoring the payout and resetting the device for the next play.

Claims

1. A game apparatus of the type having a set of cyclically rotational movable symbol-bearing members which are activated and set into motion by a player to be subsequently stopped with the alignment of the symbols on the members serving as a determination of the score-award for the game played, comprising in combination:

means activated by the player for setting the symbol-bearing members into motion;

each of the symbol-bearing members having adapted for rotation therewith coding means for defining a predetermined number of possible symbol stopping positions and comprising alternate address and decode information elements for each of said symbols, the address and decode information for each symbol being unique to that symbol;

means for reading the address information elements for said symbols as the symbol-bearing members pass a predetermined point in their respective rotational cycles and for detecting the instantaneous position of the symbol-bearing members;

a generator for generating on a random basis numbers corresponding to the address information elements for the various stopping positions of the symbol-bearing members;

means for selecting a number from the generator and for stopping each symbol-bearing member at the position corresponding to the address information elements for the random number selected;

means for reading the decode information elements for each symbol-bearing member after each member is stopped to detect the stopped position of each member and for determining the relative positions of said members;

means for determining the score-award for the game played based on the relative stopped positions of said symbol-bearing members.

2. A game apparatus as defined in claim 1 wherein the means for selecting a number selects said number for one movable member and stops said movable member at the position corresponding to the number and thereafter sequentially selects numbers and stops each movable member in sequential order.

3. A game apparatus as defined in claim 2 wherein said means for detecting the position of the movable members comprises elements in sectors on each movable member in combination with means for sensing said elements and signaling the member position.

4. A game apparatus as defined in claim 3 wherein said means for detecting the instantaneous position of the movable members comprises groups of openings at each sector of said movable member with the relative positioning of the openings varying to indicate the various positions of the movable members, in combination with light-emitting means and a light detector positioned on opposite sides of the movable member with the light detector generating signals responsive to the positions of the openings in the sector of the movable member aligned between the light-emitting means and the light detector.

5. A game apparatus as defined in claim 4 wherein said movable member sectors each include openings indicating the position of the movable member and openings indicating a code corresponding to the symbol on the movable member corresponding to said position.

6. A game apparatus as defined in claim 5 wherein said means for detecting the position of said movable member detects the openings indicating the position of said movable member during the stopping of the movable member in response to the random number received, and thereafter detects the openings indicating the code corresponding to the symbol for detecting the stopped position of the movable member for determining the score-award for the game.

7. A game apparatus as defined in claim 1 wherein said movable members comprise a set of reels and said means for selecting said random numbers selects a first number and stops a first reel at a position corresponding to that number and thereafter sequentially selects numbers and stops a corresponding reel until all of the reels are brought to an at-rest position.

8. A game apparatus as defined in claim 7 including means for recording the code corresponding to the at-rest position of each reel as the reel is stopped.

9. A game apparatus as defined in claim 8 wherein said means for determining the score-award of the game compares the code of the reels in the stopped position and the recorded code for the reels in the at-rest position and makes such score-award determination only if said codes correspond.

10. A game apparatus as defined in claim 1 wherein said alternate address and decode information elements for each of said symbols comprise a plurality of light transmitting means disposed in alternating sectors of the movable members and having different patterns for each symbol stopping position, said apparatus further comprising a light emitter positioned to emit light onto the light transmitting means and light detecting means for sensing the light from the light transmitting means and signaling the pattern of light to thereby indicate the sector of the movable member from which the light is transmitted, the symbol stopping position of said member and the stopped symbol for score-award determination.
