PlayNook is the home of interactive audio books: stories you listen to and play as the main character. An AudioGame is an experience halfway between an audiobook and an interactive fiction game. Professional voice actors narrate the story; you decide what happens next. Choose with a tap or simply speak your choice out loud! HOW IT WORKS • Listen: stories with voices, music and sound design • Choose: at key moments the story stops and asks you to decide. Some choices are timed, some need an item you've found, some change your fate forever • Roll the dice: some actions need luck. Roll a virtual 20-sided dice (D20). Tap it, or just say "Roll the dice!" YOU ARE THE HERO • Stats: earn Story Points with your choices, collect Gold, build skills like strength and charm • Health: wrong choices can wound you. Lose all your health and it's game over, unless you've reached a checkpoint • Your Bag: gather items in your Inventory, discover secrets in your Journal, unlock Badges as you play REPLAY EVERYTHING WITH JOURNEYS (NEW) Every chapter has up to 5 independent save slots called Journeys.
