One Clue Crossword is divided into Chapters. Each chapter contains fifteen puzzles to complete, arranged on a mini grid.

You can attempt the puzzles in each chapter in any order. Each puzzle requires tokens to unlock.

Each completed puzzle reveals a letter on the mini grid - when you complete words on this grid, you'll earn bonus rewards.

When you complete all the puzzles in a chapter, this unlocks the 'Boss' puzzle for that chapter, a special puzzle that when completed unlocks the next chapter!
