What This Game Is
Fifteen is a self-contained logic puzzle built around one clear objective. Each new board gives you a fresh problem to solve, so it works well for quick sessions and repeated play.
Slide the tiles around to arrange them into order.
How to Play
This game can be controlled with the mouse or the keyboard. A left-click with the mouse in the row or column containing the empty space will move as many tiles as necessary to move the space to the mouse pointer.
Most puzzles in this collection reward deduction more than speed. Focus on the most limited choices first, use the clues to narrow the board, and avoid guesses unless the puzzle mode clearly expects them.
Beginner Tips
- Start with the area that has the strongest clue or the fewest legal options.
- Use marks, notes, or temporary indicators if the puzzle supports them.
- Try to preserve flexibility instead of committing too early when multiple moves look possible.
- If the board gets messy, restart a fresh puzzle and apply what you learned from the first run.
