Slider

Slider is a 4x4 sliding tile puzzle game. It is designed for a single player and features sixteen tiles arranged in a 4-by-4 grid. The tiles are labeled from 1 to 15, with one tile left unlabeled. The game begins with the unlabeled tile in the upper-left corner, while the remaining tiles are randomly distributed across the grid. Your goal is to arrange the tiles in ascending order, placing tile 1 in the top-left corner and the unlabeled tile in the bottom-right corner, as illustrated in the image below. You will be racing against a countdown timer, which you can set (in minutes) before starting the game. Tiles can be moved by sliding them up, down, left, or right, either by clicking the on-screen buttons or using the arrow keys on your keyboard.
