Daily puzzles, streaks and unlimited play — anywhere.
Your goal is to clear the stack of letter tiles by finding all the hidden 5-letter words.
At any given moment, there is only one correct word that can be spelled. Find it to move on to the next one.
Pick Letters
Tap an exposed (top-layer) tile to move it into the word slots below. Picking a tile may uncover tiles underneath, making them available.
Spell a Word
Keep picking letters until all 5 slots are filled with the correct word.
Correct!
Undo
Tapped the wrong tile? Tap a letter in the slots to return it to the stack. Note: any letters placed after it will also be returned.
Tap to return O, R
Wrong Word
If the 5 letters don't form the correct word, they'll automatically fly back to the stack.
Not a valid word — tiles fly back
