The StarsHeaven Puzzle
It ought to be simple to set the seven different pieces of this puzzle in the tray, and yet the picture shows a frequent problem. The opening that is left in the tray demands a 60º piece while the piece you have left is a 90º piece! Perfect for the coffee table, the StarsHeaven really "catches" people because it always seems so very close to being solved-- and yet people have worked on it for more than an hour and given up without solving it!

The puzzle has 18 solutions, but only 7 pieces. The name StarsHeaven, if said quickly, also sounds like "Star Seven" so named for the 7 pieces that form into a star. The seven all-different pieces are a Japanese selection of pieces.
Three of the pieces of this puzzle are shown below:

They are each made of three joined circles, one in 90º, one in 60º, and one in a combination of the two, 150º (90º + 60º). The other four pieces of the puzzle are tetramix pieces (see my article on Mixed Angle Puzzles for an explanation) which use a mixture of 90º and 60º angles. It sounds complicated, but the pieces quickly and naturally fall into alignment as you place them--until you get to the last few pieces!
