SpellSlide

SpellSlide is a daily word puzzle where you slide letter tiles into place to form valid words in every row and column, combining the mechanics of a sliding tile puzzle with crossword logic.

You're given a grid with some tiles fixed in place and others that can slide into an empty gap. One cell is marked with a ? representing a mystery letter you'll guess once everything else is arranged. Your goal is to shuffle the movable tiles until all rows and columns spell valid words.

• Tap a tile next to the empty space to slide it into the gap.
• Dark tiles stay put. Light tiles move.
• Arrange letters so every row and column forms a real word.
• A daily clue references both words that intersect at the mystery letter.
• Once tiles are positioned, guess the missing letter that completes both crossing words.
• Fewer moves and wrong guesses earn a better score.

Why we like it:

• ✅Blends spatial reasoning with vocabulary in a way that feels fresh every day.
• ✅The mystery letter adds a satisfying final twist after you've done the heavy lifting.
• ✅Low pressure and quick enough to knock out in a coffee break.

Hint: Start by identifying which words the clue is pointing to, then work backward. Lock in the fixed tiles as anchors and build around them. The mystery letter often clicks into place once you've got the rest sorted.
