Dive into a vertical card strategy duel set in sunken deep-sea ruins. Each turn, tap cards in your hand to form a valid combination—pairs, triples, ascending lines, unified suits, and higher royal patterns. Playing a formation converts it into tidal energy and attack power, dealing damage while building a crown gauge. Fill the gauge to empower your next strike with a domain boost. Four suits shape your tactics: Obsidian Shadow raises critical hits, Starlight Heart restores vitality, Royal Gem improves rewards, and Mystic Grove amplifies skills. Use consumable items mid-battle, awaken cards for stronger multipliers, and choose among Adventure chapters, Endless high-score runs, Daily rule twists, or a Custom Deck build. Survive limited turns, outpace rival health, and claim the lost undersea throne through smarter formations—not raw luck alone.
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 6 screenshots above are Maplestarrum's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Maplestarrum runs a dark set where the background shifts from screenshot to screenshot (first shot #0C0C2C) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #CCA434, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
