Number Slide, from Amazon Digital Services, is free in the Kindle store tonight. Like all Active Content, this one is limited to those in the US.Book Description
Number Slide brings the classic sliding number puzzle to Kindle.
In Number Slide, you are presented with a set of numbered tiles on a grid. One tile is removed and the remaining tiles are scrambled. The objective is to get all the tiles into proper numeric order by moving the tiles into the one open space and sliding them around until they are back where they belong.
Number Slide features hundreds of randomly generated game grids for you to enjoy. You can choose between a small (3x3), medium (4x4) or large (5x5) puzzle grid with larger grids being more difficult. You can also challenge yourself by trying to beat your best time on each puzzle.
Number Slide comes with instructions as well as tips to help you if you get stuck. You can choose if you wish to move tiles manually (where you select each move with the 5-way button first), or automatically (no need to press the 5-way button).
