Heaven and Hell: One Night Billionaire

天国と地獄 ～ワンナイト大富豪～ ("​Heaven and Hell -one night billionaire-") is a fast-paced card game based on the classic Daifugo (or Ladder Climbing) mechanics, enhanced with new elements like "takeover" (adding cards to steal an opponent's meld) and customizable "rule tiles." Players aim to empty their hand first to gain high-value score tokens across 3 quick rounds. With dynamic rule flips and tactical takeovers, players can experience wild reversals of fortune in just 5–10 minutes.
