Players take turns playing cards whether singles, pairs or triples with the only rule being that every play must outrank the previous one. The goal is simple but competitive as the first player to empty their hand becomes the King while the last remaining player takes the role of Slave. The mechanics create a fast paced cycle of strategy, unpredictability and rivalry that fits perfectly with the lively tone of this new collaboration.
A dedicated crossover trailer is also available to showcase the style, humor and personality of the Bay Riffer collaboration as it blends seamlessly into the world of Slap ‘em UP! This marks a major milestone for the title and opens the door for more creator driven partnerships in the future as the Southeast Asian gaming audience continues to grow and support local gaming content.
