The present invention relates a puzzle device which is played by spatially re-orientating the puzzle device. The basic aim is to get a small weight, such as a small ball bearing, from one chamber to another chamber of the puzzle device by spatially re-orientating the puzzle device, but without being able to see the ball bearing.

SUMMARY OF THE PRESENT INVENTION In accordance with one aspect of the present invention there is provided a puzzle device characterised in that it comprises: a plurality of chambers, comprising a first set of chambers and a second set of chambers; and, weight means; wherein said first set of chambers comprises at least one chamber which communicates with at least one other chamber of said plurality of chambers, and each of said chambers of said second set of chambers communicates with at least two chambers of said plurality of chambers such that said weight means is movable from one of said chambers to another of said chambers upon spatial re-orientation of said puzzle device in a selected manner.

In an embodiment of the present invention described herein, the puzzle device is in the shape of a cube with the chambers arranged inside it. There are openings in the

walls of these chambers so that a small weight, such as a small ball bearing, can pass through these openings from one chamber to another chamber when the puzzle device is turned, i.e. spatially re-orientated, by the person playing with the puzzle device. One chamber is a "start" chamber and another chamber is an "end" chamber. The chamber communicate sequentially from the "start" chamber through to the "end" chamber.

To solve the puzzle device it is necessary to get the ball bearing from the "start" chamber to the "end" chamber (or vice versa) by repeatedly turning the puzzle device so that the ball bearing continues to fall from one chamber into the next chamber until it finally comes into the "end" chamber. However, the outside of the puzzle device is opaque (except for the "start" and "end" chambers) so that the passage of the ball bearing through the chambers cannot be seen. This means that the person playing with the puzzle device must listen for the sound of the ball bearing as it falls from one chamber to the next to know that it has advanced. Then, the person knows that he/she must again turn the puzzle device until the ball bearing falls into the next chamber, and so on. A counter is provided to count the number of times the puzzle device is spatially re-orientated. A timer is provided to time the time taken for the person to solve the puzzle device.

The puzzle device is formed as a three (3) dimensional array of the chambers.

Preferably, the puzzle device is in the shape cf a cube. BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF THE INVENTION In Figures 1 and 2 there is shown a puzzle device 10 comprising chambers shown generally at 12 (in Figure 2) and a weight which may be in the form of a ball or ball bearing 14 (also shown in Figure 2). Each of the chambers 12 communicates with two other chambers 12 except for a first ("start") chamber and a second ("end") chamber, which are identified as 12' and 12", respectively, for easy reference. The first and second chambers 12' and 12" form a first set of chambers and the remainder of the chambers 12 form a second set of

chambers. The first chamber 12' communicates with one of chambers 12 of the second set of chambers, and the second chamber 12" communicates with another one of the chambers 12 of the second set of chambers. A path or passage is defined from the first chambers 12' , through the chambers 12 of the second set of chambers to the second chamber 12" (and vice versa). The chambers 12 are formed by walls 20. The walls 20 are provided with openings 22 by which chambers 12 communicate. The walls 20 of the first chamber 12' are provided with an opening 22 such that the first chamber 12' communicates with one of the chambers 12 of the second set of chambers. The chamber of the second set of chambers which communicates with the first chamber 12' can be seen in Figure 2 and is identified at reference numeral 12a. Thus, the first chamber 12' has one opening 22 by which it communicates with the chamber 12a, which is one of the chambers of the second set of chambers. Similarly, the walls 20 of the second chamber 12" are provided with an opening 22 such that the second chamber 12" communicates with another one of the chambers 12 of the second of chambers (not being the chamber 12a). However, the chamber of the second set of chambers with which the second chamber 12" communicates is obscured in the drawings but for ease of reference is hereinafter referred to as the chamber 12b. Thus, the second chamber 12" has one opening 22 by which it communicates with a chamber 12b of the second set of chambers. The walls 20 of the chambers 12 of the second set cf

chambers are provided with two openings 22 such that each chamber 12 of the second set of chambers communicates with two other chambers 12 of the puzzle device 10. Thus, each of the chambers 12 of the second set of chambers communicates with two other chambers 12 of the second set of chambers, except for the chambers 12a and 12b. The chamber 12a communicates with one chamber 12 of the second set of chambers along with the first chamber 12'. Similarly, the chamber 12b communicates with one chamber 12 of the second set of chambers along with the second chamber 12". Accordingly, each of the chambers 12a and 12b (of the second set of chambers) also communicates with two chambers 12 of the puzzle device 10. In this way, the chambers 12 of the puzzle device 10 communicate sequentially to form the path or passage hereinbefore described.

The chambers 12 which are in communication with one another are adjacent. The puzzle device 10 has the chambers 12 arranged in a three (3) dimensional array. In such arrangement, the chambers 12 are located inside the body of the puzzle device and also adjacent the outside surface/s 23 of the puzzle device 10. The first chamber 12' is positioned such that at least part of its walls 20 is formed as part of an outside surface 23 of the puzzle device 10. Further, at least a portion of aforesaid part of the walls 20 of the first chamber 12' is formed such that interior of the first chamber 12' is visible, e.g. by being transparent or translucent. The

second chamber 12" is positioned and formed in a similar manner.

The outside surface/s 23 of the puzzle device 10 is opaque

(except for the walls 20 of the first chamber 12' and second chamber 12" as hereinabove described) such that the interior of the puzzle device 10 is not visible.

Preferably, the first and second chambers 12' and 12" are visibly distinguishable from the exterior of the puzzle device 10, e.g. their walls 20 may be tinted in different colours.

The puzzle device 10 also comprises a counter device.

The counter device is used in counting how many times the puzzle device is spatially re-orientated as will be hereinafter described. Figures 3 and 4 show an embodiment of a counter device 24. The counter device 24 comprises a chamber 26 defined by walls 28. The chamber 26 is sealed. Each of the walls 28 is provided with a pair of electrical contacts 30 on the inside of the chamber 26. Electrical leads 32 extend from the electrical contacts 30 to electronic counter circuitry 34.

An electrically conductive mass of material 36 is contained inside the chamber 26. The mass of material 36 completes an electric circuit when it comes into contact with the pair of electrical contacts 30 on a wall 28 of the chamber 26.

Preferably, the mass of material 36 is a blob of mercury. Each time the puzzle device 10 is spatially re-orientated such that the mass of material 36 moves from the contacts

30 of one of the walls 28 of the chamber 26 onto the contacts 30 of another one of the walls 28, an electrical circuit is completed. This action registers on the electronic counter circuitry 34 which keep a cumulative tally of the number of such movements of the mass of material 36, and therefor, of the number of re-orientations of the puzzle device 10.

Preferably, the counter device 24 is provided substantially at the centre of the puzzle device 10. The puzzle device 10 further comprises a, timer 38 which includes start, stop and reset functions.

An electronic display 40 is provided on an outside surface of the puzzle device 10, mounted on a small panel 42. The electronic display 40 may be a liquid crystal display. The electronic display 40 may function as a digital display to display the cumulative number of re-orientations undergone by the puzzle device, e.g. in an incremental manner. The electronic counter circuitry 34 can be reset to recommence counting. Alternatively, the electronic display 40 may function to display elapsing time, i.e. as a digital display for the timer 38. Controls (not shown) may be provided adjacent the electronic display 40 for operation and selection of the display functions. A power source (not shown), e.g. a cell or battery, may be provided behind the electronic display 40, adjacent the electronic counter circuitry 34 and the timer 38. The power source powers the electronic counter circuitry 34, timer 38 and electronic display 40. The power source can

be accessed for replacement, etc, by removing the panel 42 which carries the electronic display 40. The electronic counter circuitry 34, timer 38 and power source take up space in the interior of the puzzle device 10 and are not visible from the exterior thereof. Only the electronic display 40 on an outside surface 23 of the puzzle device 10 is visible.

Preferably, the puzzle device 10, chambers 12 and the counter device are of substantially oblong or cube form, as shown in the drawings 1 to 4.

With both the puzzle device 10 and chambers 12 being of cube form, the first and second chambers 12' and 12" may be provided at diagonally opposed corners of the puzzle device 10. This is best seen in Figure 1. Additionally, the three walls 20 of the first and second chambers 12' and 12" that are at the outside surface 23 of the puzzle device 10 are substantially transparent or translucent such that the interiors of the first and second chambers 12' and 12" are visible. The provision of the puzzle device 10 as a cube means that it has six exterior faces which make up its outer surface/s 23.

Similarly, the provision of the chambers 12 as cubes means that each chamber 12 is defined by six walls 20, with adjacent chambers 12 sharing a common wall 20.

With the puzzle device 10 and the chambers 12 being of cube form, the puzzle device 10 is in the form of a 3 dimensional cubic array of chambers 12 of cube form, as is shown in Figures 1 and 2.

Preferably, the cube form puzzle device 10 is five (5) chambers 12 cubic. This produces 5 5 5 = 125 chambers 12. However, the central space in the puzzle device 10 is occupied by the counter device 24. The electronic counter circuitry 34, timer 38 and power source take up additional space; the space that would be taken up by five (5) chambers 12 is allocated to this. In this way a total space that would have been occupied by six (6) chambers 12 is taken up, and extends from one face (outer surface 23) of the puzzle device 10 into the centre thereof. This leaves 125-6 = 119 (useable) chambers 12 through which the ball 14 may pass. An odd number of useable chambers 12 is found desirable so that the first and second chambers 12' and 12" may be positioned at diagonally opposed corners of the puzzle device 10.

The counter device 24 shown in Figures 1,3 and 4 is of cube form. Thus, there are six (6) walls that go to make up the chamber 26 of the counter device 24. The respective pairs of contacts 30 are then positioned in substantially the middle of each wall 28. The chamber 26 conveniently takes up the space that would have been occupied by a central chamber 12.

An alternative embodiment of a counter device 44 is shown in Figure 5. The counter device 44 comprises a chamber 46 which has a spherical wall 48. The counter device 44 has six (6) sets of contacts 30 with leads 32 extending therefrom. The six (6) ^' sets of contacts 30 are symmetrically spaced. A mass of material 36 (obscured) is contained in the chamber 46 of

the counter device 44.

A further embodiment of a counter device 50 is shown in Figure 6.

The counter device 50 shown in Figure 6 comprises a chamber 52 which has six (6) lobe like forms 54 which meet at the centre. The lobe like forms 54 are symmetrically spaced and meet at a central core 56. Respective pairs of contacts 30 are provided at the outer extremity of each lobe like form 54. Leads 32 extend form the contacts 30. The counter devices 24,44 and 50 are provided with six (6) sets of contacts 30 so that one set of contacts 30 corresponds with a respective face (outer surface 23) of the puzzle device 10 of cube form. In each case, the counter device 24,44 or 50 is arranged in the middle of the puzzle device 10 such that a set of contacts 30 faces a respective face of the puzzle device "square on". In this way, when the puzzle device 10 is spatially re-orientated through substantially 90° such that a new face is uppermost, the mass of material 36 falls onto a new set of contacts 30 to register the spatial re-orientation of the puzzle device 10.

The manner of use and operation of the puzzle device 10 will now be described.

The object of the puzzle device 10 is to move the ball 14 from the first chamber 12' , through the chambers 12 of the second set of chambers to the second chamber 12" (or vice versa) by repeatedly spatially re-orientating (or turning) the puzzle device 10 through substantially 90° about a substantially horizontal axis. Conveniently, the puzzle

device 10 is held with an outer surface 23 uppermost.. Thus, if at the start the ball 14 is in the first chamber 12' , the puzzle device 10 is spatially re-orientated through substantially 90° such that the ball 14 falls through the opening 22 into the chamber 12 that is adjacent the first chamber 12'. This spatial re-orientation procedure is repeated until the ball 14 passes into the next chamber 12, and so through all of the chambers 12 of the second set of chambers and falls into the second chamber 12".

However, since the outside surface/s 23 of the puzzle device 10 is/are opaque (except for the walls 20 of the first and second chambers 12' and 12"), this means that the user is unable to see the passage of the ball 14 through the chambers 12 of the second set of chambers. The user must listen for the sound of the ball as it falls from one chamber 12 to the next chamber 12 to know it has advanced. The user then knows that he/she must then again spatially re-orientate the puzzle device 10 so that the ball 14 can fall into the next chamber 12, and so on. However, the user must also use his/her memory and skill in spatially re-orientating the puzzle device 10 to ensure that the ball 14 continues to move in the desired direction through the passage defined by the chambers 12; thus, if the user makes an error he/she could spatially re-orientate the puzzle device 10 so that the ball 14 falls back into the last chamber 12 from which it came, rather than into the next chamber 12. In this way, the puzzle device 10 provides entertainment and challenge to the user in solving the

puzzle device 10.

Figure 2 shows the passage defined by the first flow chambers 12. To get the ball 14 into the chamber 12a, it is necessary that the puzzle device 10 is spatially re-orientated so that the face A becomes uppermost. To then get the ball 14 from the chamber 12a into the next chamber 12, it is necessary that the puzzle device 10 is returned to the spatial orientation shown in Figure 2 (i.e. with the face 13 uppermost). This process is continued until the ball passes through all the chambers 12.

The puzzle device 10 may be re-orientated once only or more times before the ball 14 alls into the net chamber 12. The aim is to have the ball 14 pass through all the chambers 12 in the least number of spatial orientations of the puzzle device 10.

Figure 7 shows an embodiment of a specific sequence for the passage through the chambers 12. The five layouts of Figure 7 each represent the chambers 12 of one of the five levels I,II, III, IV arid V of the puzzle device 10. The numbers in these layouts show the sequential path that is followed by the ball 14 through the different levels of chambers 12.

Each time the puzzle device 10 is spatially re-orientated through substantially 90° (about a substantially horizontal axis), the mass of material 36 will move from one pair of contacts 30 to another. In this regard, the counter devices 24,44 and 50 function in similar manner). As previously described, this completes an electrical circuit and the electronic counter circuitry 34 counts this as a

spatial re-orientation of the puzzle device 10. (Spatial orientations about a substantially vertical axis are not counted) . The electronic counter circuitry 34 maintains a cumulative tally of the number of times the puzzle device is so spatially re-orientated from the start to the end. This tally is displayed in digital form on the display 40. The timer 42 also times the time elapsed from commencing to solve the puzzle until the end. This can also be displayed on the display 40. Modifications and variations such as would be apparent to a skilled addressee are deemed within the scope of the present invention.
