“Pentomino” Puzzles There are 12 ways of arranging 5 joined up squares – the “Pentominoes” A “domino” is made up of two squares So, a “tromino” has three And a “tetromino” has four

“Pentomino” Puzzles Pentomino puzzles are very popular. They have a seeming endless variety of solutions. Here are the 12 pieces in rectangles

“Pentomino” Puzzles - variations Six of the pentominoes (on the left) can be made with 2 pieces of wood, size 2 and 3. The others are more complex.

“Pentomino” Puzzles The simplified set of six pentominoes can still make some interesting shapes.

“Pentomino” Puzzles Finding a good name for a puzzle is always important. Fortunately the shapes themselves suggest a name “SPLITV” – a bit hard to pronounce!

“Pentomino” Puzzles - SPLITV The puzzle leaflet is important but it requires quite a bit of work

“Pentomino” Puzzles - Tetrominoes The set of five tetrominoes cannot make a rectangle, but a double set can (and there are many solutions – so it’s a nice puzzle)

“Pentominoes” and “Hexiamonds” The word “pentomino” is like “domino” (made up of five squares, not two) So the word “hexiamond” is like “diamond” (made up of six triangles, not two) some of the shapes made with triangles

“Hexiamonds” There are 12 different arrangements of triangles possible. They make a nice (but difficult) puzzle that can be put together to make many shapes

“Tetriamonds” and “Pentiamonds” Four triangles can be put together in 3 ways to make “tetriamonds” And five triangles make 4 “pentiamonds” The shapes are quite easy to make

The “Delta” puzzle The 3 tetriamonds and 4 pentiamonds together make a set of 7 pieces that makes a good put-together “Delta” puzzle

The “Delta” puzzle The 3 tetriamonds and 4 pentiamonds together make a set of 7 pieces that makes a good put-together “Delta” puzzle with many possible shapes

The “Delta” puzzle And, as always, a leaflet has to be produced, something like this:
