1.
Mondrianize-it! This line of puzzles, inspired by the artworks
of the Dutch artist Piet
Mondrian, consists in dividing the large square
board with straight lines along the small chequered
squares in order to partition the board into squares
and rectangles so that each square holds exactly one
red star and each rectangle, one red dot (see example
below).

2.
Reclone-it! Using the grid dots you have to repartition the large
gray shape within the board opposite into 2 smaller congruent
shapes (that is shapes that coincide exactly when superimposed).
Two congruent shapes can be identical or mirrored, as
illustrated in the examples below.

3.
Pathfinder Draw pathway lines on the pink board to join similar
symbols together (triangle to triangle, pentagon to
pentagon, etc.) Rules
of
the
game:
1.
No
line
may
cross
another line.
2.
No
line
can
cross
the
black bands
(see
description
at
the
bottom
of
the puzzle).
3.
Only
ONE
line
can
cross
the band
with
stripes.
4.
The
wavy
dotted
band MUST
be
crossed
by
at
least
THREE
different connecting
pathway
lines.
5.
Respecting
the
previous
points,
every pathway
line
should
be
the
SHORTEST
possible.

4.
Pythagoras This game, involving square patterns, is a tribute
to the Greek mathematician Pythagoras and was designed
to stimulate your visuospatial skills! Blacken a white
dot within the board so that, starting from this dot,
the largest number of perfect squares can be drawn by
joining together their vertices. You can obviously join
together only black dots as shown in the example below.

5.
Calderize-it "Calderize-it" is a balance
puzzle line inspired by the kinetic artworks of
the American artist Alexander
Calder who was well known for his stunning "mobile
sculptures".
You
have
to
ascribe
whole-number
weights
(1, 2,
3,
etc...
up
to
13)
to the
hanging
masses
of
the
balance
below in
order
to
maintain
the
rods
horizontal (horizontal
rods
indicate
there
is
equal
torque on
both
sides).
The torque of
each
mass
is
its
weight
times its
distance
from
the
fulcrum
(=
pivot point).
The
example
opposite
balances
since: 2 x
7
= 1 x
2
+ 3 x
4.
Note
also
that
the
total
weight
of any
balanced
rod
equals
the
sum
of all
the
hanging
masses
distributed
underneath
it, in
the
example:
7
+
2
+ 4
=
13.

6.
Mag-line Mag-line is a neat Sudoku variant
invented by the French puzzle designer Didier
Faradji. Each column and each row of the
puzzle must contain the digits from 1 to 9 (except
one) once. Moreover, each number in the green box
is the sum of the first 4 digits of the respective
row or column. (You can fill the empty boxes online)

7.
Strimko Strimko is a clever logic puzzle involving numbers
invented by the Grabarchuk
Family.
Fully
fill
in
the
given
grid
with missing
numbers
(1
through
6)
observing three
simple
rules:
1.
Each
row
must
contain
different
numbers.
2.
Each
column
should
contain
different
numbers.
3.
Each
stream
must
contain
different
numbers.
