From the publisher:
Whether you are a longtime fan of Phase 10, or you're new to the game, take on the challenge of Phase 10 Twist! If you play your cards right, you can out-think your opponents and maximize your luck! Take risks and try to advance to the finish faster or play the safe and steady route... whichever way you want to play, you'll be challenged, excited, and even a little twisted.
This looks to add multiple draw piles, a board to progress upon and optional push your luck out of turn phase selections from a separate draw pile. It's still Phase 10, but it looks to have been brought some much needed gameplay additions.
