About this game
Slide 15 is a classic sliding puzzle where you push tiles into the empty space to line up numbers in order. Choose a board size from 3×3 to 5×5 — fewer moves and a faster time lead to a higher score.
How to play
- First, choose the board size you want to solve.
- Tap a tile next to the empty space, or push tiles with the arrow keys or a swipe.
- Arrange the numbers in order starting from 1.
- It's complete once every number is in the right order.
Tips
- Taking more moves or more time reduces your score.
- Finishing within the par move count earns a bonus.
- Solving row by row from the top and column by column from the left keeps things clear.
- It helps to remember a set method for finishing the last two rows at once.
- Once you get the hang of it, try a bigger board like 5×5 for a higher base score.
FAQ
- Can I continue a puzzle I was solving?
- Yes, choosing resume picks up from your saved move count and time.
- How is the score calculated?
- The base score for that size is reduced by your moves and time, then a bonus is added if you finish within par.
- Are best records saved?
- Yes, a best score is kept for each board size so you can try to beat it later.
