MIRRORKAL / YOU AND Mona Lisa (Pat. US4898560)

comes with 2 problems

Difficulty: easy / medium

Playing Time: < 45 minutes

The aim of the warmup challenge is to make the small Mona Lisa visible

in the center and the remaining eight cubes shall work as mirrors.

No single cube picture other then the Mona Lisa shall be recognizable.

The problem is relatively easy to solve. The first step is to find the small Mona Lisa

which is depicted at one side of a cube.

Then you have to think how the mirrors of two cubes have to be arranged.

To meet the challenge, the complete Mona Lisa has to be visible.

This problem is more tricky,

as you search small pictures like in a normal jigsaw puzzle.

Solution

Equal7

Puzzle Design Competition 2011

Difficulty: easy - medium

Playing Time: < 45 minutes

similar puzzles: Varikon Box 2 x 2 x 2, Vadasz Cube

Equal7 consists of seven red dices

which are enclosed in a transparent plastic cube of the size 2 x 2 x 2.

All seven dices are identical, but have different orientations.

They are also different from an ordinary dice in regards to their numeration:

Instead of having six points on one side, they have a blank side.

Moreover, the sum of two opposite sides equals always five.

The plastic cube container has a special shape on one corner

so that it can stand on this corner.

In this position, the cube container on the top has dice points

with either one, three or five points.

If Equal7 is standing on the corner,

then the observer gets the impression

that it consists out of eight dices.

There are four different tasks to Equal7.

The aims are to shift the dices in such a way

that all sides show either 10, 11, 12 or 7 points.

Thereby, the dices are moved by overturning the 2 x 2 x 2 cube container.
