## Abstract

The apparatus is a puzzle which includes a central toroidal channel with a rotating cogged wheel therein. A plurality of hollow toroidal rings intersect perpendicular to the central toroidal channel. These toroidal rings include balls of different colors. These balls pass from toroidal ring to toroidal ring through the toroidal channel. The object of the puzzle is to intermix balls of different colors and then rearrange the balls so that all balls of a single color are in a single toroidal ring.

## Claims

### Claim 1

A puzzle apparatus including:
a central closed loop channel;
a plurality of peripheral closed lop channels intersecting substantially perpendicularly with said central closed loop channel and in communication with said central closed loop channel, said peripheral closed loop channels being toroidal with a circular path and a circular cross section, and said central closed loop channel being toroidal with a circular path;
a plurality of spherical balls which travel within said central closed loop channel and said plurality of peripheral closed loop channels, said balls being provided in M groups of N balls each, each of M groups being a different color one from another, and wherein M is equal to the number of peripheral closed loop channels;
first means for urging said balls to traverse said central closed loop channel;
second means for urging said balls to traverse said peripheral closed loop channels;
wherein said balls travel a path including said central closed loop channel and said plurality of peripheral closed loop channels in response to said first and second means for urging.

### Claim 2 (depends on 1)

The puzzle apparatus of claim 1 wherein said first means for urging is a first wheel within said central closed loop channel, said first wheel including first means for engaging said balls within said central closed loop channel.

### Claim 3 (depends on 2)

The puzzle apparatus of claim 2 wherein said second means for urging is a second wheel within each of said peripheral closed loop channels, said second wheels including second means for engaging said balls within said respective peripheral closed loop channels.

### Claim 4 (depends on 3)

The puzzle apparatus of claim 3 wherein said first and second means for urging include cog means.

### Claim 5 (depends on 4)

The puzzle apparatus of claim 4 wherein said first wheel and said second wheels include knob means for the user to turn thereby urging said balls around respective said central and peripheral closed loop channels.

### Claim 6 (depends on 5)

The puzzle apparatus of claim 5 wherein said knob means include a first knob means at a first side of respective said central and peripheral closed loop channels and a second knob means at a second side of respective said central and peripheral closed loop channels.

### Claim 7 (depends on 6)

The puzzle apparatus of claim 6 wherein said central and peripheral closed loop channels are formed from a shell of substantially clear plastic.

### Claim 8 (depends on 7)

The puzzle apparatus of claim 7 wherein said shell includes apertures engaging said first and second knob means thereby providing axes of rotation for said first and second means for urging.

### Claim 9 (depends on 8)

The puzzle apparatus of claim 8 wherein said apertures are substantially round and wherein said first and second knob means include a round cross section to be engaged by respective said apertures.

### Claim 10 (depends on 9)

The puzzle apparatus of claim 9 wherein said axes of rotation for each of said second means for urging are substantially on a single plane.

### Claim 11 (depends on 10)

The puzzle apparatus of claim 10 wherein said axis of rotation for said first means for urging is substantially perpendicular to said single plane.

### Claim 12 (depends on 11)

The puzzle apparatus of claim 11 wherein said shell is substantially symmetric about said single plane.

### Claim 13 (depends on 12)

The puzzle apparats of claim 12 wherein said peripheral closed loop channels are substantially equally spaced about said central closed loop channel.

### Claim 14 (depends on 13)

The puzzle apparatus of claim 13 wherein said first means for urging urges two balls from each peripheral closed loop channel to traverse said central closed loop path to successive peripheral closed loop channels.

### Claim 15 (depends on 14)

The puzzle apparatus of claim 14 wherein each of said knob means includes a knurled portion.
