Read full description

A word puzzle with the rhythm of solitaire. Move letter cards between stacks, uncover hidden letters and bring each word together. One small move can open up the whole board. Explore more than 1,000 crafted levels, from gentle first puzzles to tricky mystery words and tougher boss boards. When you need a fresh angle, use a hint, shuffle the cards or add a column. Come back for the daily puzzle, build a streak and discover its Golden Word. Want a quicker challenge? Versus mode puts you up against a computer opponent, with game coins at stake. Coins have no cash value and cannot be withdrawn or exchanged for real-world prizes. Collect letters to unlock background themes, choose an avatar and make the game your own.
