About Word Slide
Word Slide pairs the timeless sliding-tile puzzle with vocabulary and cognitive fitness. Slide adjacent letters into the empty space until the target word assembles itself. Tiles can never be swapped directly — every move follows classic sliding mechanics.
How to play
- Tap a tile beside the empty space, or swipe the board.
- On desktop, use the arrow keys.
- Tiles glow as they land in the right position.
- Solve the board to reveal the word, its definition, and an example.
Guaranteed solvable
Every board starts solved and is scrambled with legal random moves only. Pieces are never randomly assigned, so an impossible puzzle can't be generated.
