## What is Stack?

Stack is a block puzzle for iPhone, iPad and Apple Watch. Drop falling pieces, fill rows to clear them, and set off bomb blocks for bigger clears. Play today's Daily Challenge on either screen: the same pieces for everyone, once a day.

ON IPHONE AND IPAD
• Touch controls: swipe to move, tap to rotate, swipe down to drop softly, flick down to drop hard.
• Ghost piece shows where each piece will land.
• Line clears ripple across the board with a stepped haptic pattern.
• Daily Challenge tile on the home screen shows today's seed code and your streak.
• Game Center leaderboards, optional.
• Siri and Shortcuts: play Stack, play today's challenge, ask for your best score.
• Light and dark mode, and a short tutorial for the controls.
• Your streak and best scores are kept on each device; the daily seed is the same on both.

ON APPLE WATCH
Fully playable on your wrist with the Digital Crown, no phone needed.

Gameplay Highlights
• Classic falling-block mechanics
• Neon bomb power-ups for explosive clears
• Daily Challenge: the same seeded puzzle for everyone, once a day
• Real Game Center leaderboards and streak achievements
• Digital Crown controls on Apple Watch, touch controls on iPhone and iPad
• Quick, satisfying rounds for on-the-go play

Daily Challenge
Everyone gets the same falling-block sequence once a day, so it's a fair contest, not just a high score chase. Build a streak by playing every day, see your best score and a 7-day trend on Apple Watch, and ask Siri to check your streak without opening the app.

Power-Up Fun
Collect and activate bomb blocks to wipe rows in style with glowing effects and satisfying haptics.

Compete & Conquer
Sign in to Game Center (optional) to submit your scores to a live leaderboard and unlock streak achievements. Fully playable offline without it, your scores and streak are always saved on each device either way.
