 1. Mondrianize-it!

 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. Solution to puzzle 2 See image below © Gianni A.

 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. Solution to puzzle 4 See image below © Gianni A.
