Mathpuzzle.com has an interesting tidbit this week about “circle packing puzzles.” The idea is to fit a certain number of fixed sized discs into a given space. There’s a lot of discussion about how to create such a puzzle with a unique solution.
Passion for Puzzles has a couple of interesting puzzle games posted this week. The first is the Gaia 3d Jigsaw Puzzle which basically takes the online jigsaw puzzle game to a new level by creating a 3d environment (though as far as I can tell the puzzle is still 2d.) The other is a game called Just Skidding. It involves moving a worm to an apple over a series of blocks. The trick is that if a worm moves off of a block, the block moves in the opposite direction as long as there are no other blocks in its way.
Puzzle Monster has a new puzzle called weakest link. You are given a sequence of numbers and asked to find the one that doesn’t fit the sequence.
Smartkit features a puzzle this week called I/O. It’s one of those flash puzzles where very little information is given and you have to intuit the object. It looks a little bit like a computer circuit board.
