16

16 is an obscurely named sliding puzzle game similar to classic picture puzzle games of the time.
However instead of completing an image you slide numbered blocks 1 through 16 into order.
The game begins with the numbers in a jumbled arrangement, similar to a photo puzzle.
There is always one vacant square into which one of the four surrounding blocks can be moved.
The empty square is in the bottom right corner at the start of the game. The goal of the game is to slide all the blocks back into their original numerical sequence one by one. For a simple interface, it provides a top-down, fixed perspective of the puzzle.
This sounds fairly simple and unexciting. But the catch is that since you have only one empty square to work with when arranging the blocks in order, you inevitably place the puzzle further out of order in your attempts to solve it. As a block is slid to its proper place in the puzzle, it turns green to indicate you of its rightful place.
16 is a simple game in essence. There is no strategic gameplay involved, but it is still a mind game that passes your time with understated excitement. Though the game seems to be mostly catered towards children, there is no tightly targeted demographic as such. This puzzle game was released worldwide in 1996 for DOS.
