Each layer of the egg puzzle has some holes, which can go straight down, curve and go down or only go part way through to the other side. Each layer also spins around a center pole. The goal is to get a ball through all the layers of the egg. In the default position (slices aligned to form nice egg shape),the ball can only go through one layer at a time. The player inserts a ball into the top layer, twists that layer to the right or the left, until the ball falls through to another layer. (Metal balls work best because you can feel and hear them fall through the layer.) Twist the each layer to get the ball down to the next layer, until the ball rolls out of the bottom layer. Some holes are 'traps' and do not let the ball pass through, if this happens, invert the puzzle and go back up a layer to try again.

Step 1: Overview
The hole at position B has a variable path. Turn the top-counter clockwise until both B holes align and the ball falls to layer 2. Turn layer 2 counter-wise and the B holes will align, dropping the ball to layer 3. Layer 4 has a trap. If you turn layer 3 counter-clockwise, hole B will align with a grey hole at radius B. This hole only goes halfway through the layer and the ball is trapped. If layer 3 is turned counter-clockwise, the ball will fall into the while B hole on layer 4. Rotate layer 4 clockwise and the ball will roll through hole B in the bottom layer, and out the side of the egg.
