Royal Stack

Royal Stack is a card puzzle game for iPhone, iPad, and Android that combines falling-card gameplay with poker-hand scoring. Players steer each card into a five-wide well, using directional arrows or tapping an empty cell, then complete rows of five cards to form hands. Scores range from 100 points for One Pair to 8,000 for a Royal Flush, with higher values for stronger hands and doubled scores for clearing two rows at once. Rows that do not make a hand remain in the well, so players must manage space before the cards reach the top or the deck runs out.

The game offers nine poker hands and settings for one, two, three, five, or ten decks. Players can choose Easy, Medium, or Hard difficulty; harder settings increase the falling speed and multiply scores. Each deck count has its own leaderboard, where players can compare their best results. Royal Stack is free to play, and the team invites players to join pre-launch testing through TestFlight or Google Play.
