2D Twisty Puzzles

2D Twisty puzzles consist of several movable parts which lie in a flat frame .

There are only few moves, where only one piece is slided.
Usually several pieces are slided or rotated with one movement.

The aim is to achieve a certain order.


Columns and row shifting puzzles


Columns and row shifting puzzles have the pieces ordered in a lattice shape inside a frame.
At the border of the frame are some sliders.
The use of a slider shifts all pieces in the row(s) or column(s) before the slider.
Thereby their position changes in relation to the amount the slider is pushed.

c.) Gravity puzzles

Svetnashki
Difficulty: medium
Playing Time: < 60 minutes

The composition of this puzzle is pretty easy:
The background consists of a 2 x 2 grid,
whereby neighbour grid cells have different polarisation directions.
Analogously each of the 15 tiles have a polarisation filter.
If a tile moves from one grid cell to the next,
then the colour changes from transparent to opaque or vice versa.

Another feature of the puzzle is
that the movements of the tiles are restricted
which is due to a transparent acryl disc on the front.
Therefore only the following movements are possible:
The tiles which are situated along the edges
can be slided along the edges.
As the tiles on the inner rows and columns cannot be touched,
they can only be shifted about one position by gravity.
Shifts have the feature that no tile may be hold on
and thus all tiles in one column get shifted downwards.
That is why no gap can be created in the center.

The task is to order the tiles in such a way
that either all tiles look opaque or transparent.
It is of course also possible to create any other pattern.

  Slide Rule Duels


Slide Rule Duel Puzzles consist of two parts.
In the upper part the pieces form two to three circle segments.
In the lower part the pieces form only one circle segment.
The lower part can be moved to the left or to the right.
If the lower circle segment lies directly below an upper circle segment,
then the two circle segments compose a circle.
The pieces, which build the circle, can thereby be rotated.

Moeraki Game No.4
9 red + 9 yellow + 9 green + 21 transparent beads
Difficulty: easy
Playing Time: < 10 minutes


The puzzle consists of three closed circular orbits.
Two circular orbits intersect respectively on two places
so that there are in total 6 crossing points.
All three orbits have the same length and contain 18 beads.
Due to the 4 crossing points located on each orbit,
each orbit is divided into four sections with different lengths,
namely with 9, 2, 1 and 2 beads.
The beads are present in three different colours
(red, green and yellow).
There are 9 beads per colour
and additionally 21 transparent beads.
All beads of one orbit can be shifted along it.

The goal is to order the beads on each orbit
according to colour.

Moeraki Game No.3
8 green + 8 red + 8 yellow + 8 blue + 16 transparent beads
Difficulty: medium
Playing Time: > 120 minutes

The puzzle design captivates through its simplicity.
Thus, the puzzle consists of two closed elliptical rings
which intersect on four places.
Both orbits have the same shape and each contains 26 beads.
One orbit lies orthogonal to the other one
so that the outer shape resembles a X.
The four crossing points divide each orbit into four sections
with different lengths, i.e. with 8, 3, 8 and 3 beads.
The beads are present in 4 different colours
(red, blue, green and yellow).
There are 8 beads per colour as well as 16 transparent beads.
All beads of one orbit can be shifted along it.

Each of the 4 (8-bead long) sections on both orbits
is given a different colour.
The aim is to order the beads according to their colour
on the orbits as indicated on the board.
