Definitions

• This invention relates to a game.
• Dice may take two forms. In the first form, known as “spot dice”, the six faces of each dice show respective one, two, three, four, five and six dots. In the second form, known as “poker dice”, the six faces of each dice show respectively pictures depicting the nine, ten, jack, queen, king, and ace of a pack of cards.
• apparatus comprising a plurality of display devices each capable of displaying a number of alternative display configurations, player operable means for randomly changing the display configuration of all said display devices, a hold device associated with each display device and operable by the player to prevent the configuration of the associated display device from changing, and blanking means actuable by the player and operating to render the display unreadable until the blanking means is deactuated.
• a game comprising a set of five spot dice and a set of rules for playing the game, the rules specifying that the game proceeds by the first player throwing the dice, whilst concealing the dice calling the value of his throw and inviting the next player to accept the throw, and the next and each subsequent player having accepted the throw choosing to throw one or more of the dice to improve the throw before offering the dice to the next player, the rules further specifying that each call may be true or false, that the following player may challenge or accept the call, that the player who makes the challenge wins if the call is higher than the throw, and that each player must call an improvement on the throw he has accepted.
• FIG. 1 is a plan view of an apparatus embodying this invention.
• FIG. 1 is a circuit diagram of the apparatus shown in Figure 1.
• FIG. 1 there is shown the face 1 of an apparatus for playing a game based on dice suitable for 2 or more players.
• The- face is mounted on a case which encloses the electronic circuitry of the apparatus and the case is of suitable dimensions for holding in the hand.
• the face comprises five dice or display devices 2 to 6, a roll button 7, five hold buttons 8 to 12 associated respectively with the display devices 2 to 6, a hold cancel button 13, and a blanking button 14.
• Each display device consists of seven light emitting diodes (LEDs) arranged in an array at positions corresponding to the dots on a spot dice, i.e. with four LEDs at four corner positions, two more at the centre of two opposite sides and the seventh LED at the centre.
• LEDs light emitting diodes
• each of the display devices normally display a configuration of lit LEDs corresponding to one face of a spot dice.
• the roll button 7 When the roll button 7 is depressed the configuration change in a random manner. If one of the hold buttons is pressed, its associated display device is prevented from changing configuration but this hold action may be cancelled by pressing the cancel button 13. Ike display may be blanked by pressing the blanking button 14 and then returned by pressing the blanking button 14 a second time.
• the first player presses the roll button 7, notes the resulting throw displayed on the five dice 2 to 6, removes the display by pressing the blanking button 13, and calls this throw. His call may be true or false. He then passes the apparatus to the next player who may accept the call or challenge it prior to unblanking the display. If he challenges, then the first player looses a stake if his call is higher than the actual throw but otherwise the challenger looses. If he accepts, he may press the roll button after optionally pressing one or more of the hold buttons and play then proceeds as before until a challenge occurs. Each successive player must call a higher throw.

• the values of capacitor 39 and resistor 71 are identical to the values of the corresponding components in the remaining four channel circuits but the value of the resistor 70 and the corresponding resistors in the other channel circuits differ from channel to channel to cause the oscillators of different channels to run at different frequencies.
• the oscillator 36 is controlled by a NAND gate 38, the two inputs of which are connected to the output of a further NAND gate 39.
• One input of NAND gate 39 is connected to the junction of resistors 16 and 17, the junction of resistors 16 and 17 also being connected to one input of identical NAND gates in the remaining channel circuits.

• the hold switch 8A If the hold switch 8A is closed, then the output of flip-flop 40 will go low thereby preventing the oscillator 36 from running. A similar result will be obtained by closing the hold switches in the remaining channel circuits. If one of the hold switches is closed in error, then all the flip-flops corresponding to flip- flop 40 may be reset by closing the cancel switch 13A. Also, a short time after the roll switch 7A is released, all the flip-flops corresponding to flip-flop 40 will be reset by a clock signal from Schmitt inverter 19.

• the input of oscillator 6 ⁇ is connected to the junction of cancel switch 13A and resistor 42 and the output of this oscillator provides an input signal to oscillator 62.
• the input of oscillator 61 is connected to the output of Schmitt inverter 20 and the output of this oscillator provides a further input signal to oscillator 62.
• the oscillator 62 also receives an input signal from the output of a NAND gate 63, the two inputs of which are connected to the output of a NOR gate 64.

• the oscillators 60, 61 and 62 are tuned to different frequencies so as to produce three tones. Each time the roll switch 7A, or the cancel switch 13A or one of the hold switches is depressed, a tone signal will be emitted by the transducer 47.
• the example of the invention described above makes use of separate oscillators for the individual channel circuits. It will be appreciated, however, that other arrangements could be employed in which there is a single oscillator, dividing circuits being employed to cause the counters to run at different frequencies. Alternatively, the counters could be cascaded. As yet a further alternative there could be a single counter and a read only memory addressed by the counter and providing output signal to drive the LEDs of all the display devices. In any of these cases the hold arrangement could be in the form of a separate four latch for each display device. Other forms of display blanking means could also be used such as a hinged flap movable to a display covering position.
• the display devices could employ liquid crystal devices.
• the game is played using an electronic apparatus, the game could also be played simply by using a set of five dice.
