"Two 7s"—even if you don't have a single one, you win as long as you aren't caught. But if you get called out, you have to take every card in the pot. Enjoy thrilling psychological warfare! ■ Key Features Tense Psychological Warfare: The thicker the pot grows, the more agonizing the dilemma—do you call "Doubt" now, or wait another round? Huge comebacks are always just around the corner. Clever CPU Opponents: CPUs analyze remaining cards, pot counts, and your hand to decide when to suspect you. Choose from three difficulty levels: Easy, Normal, and Hard. Play Offline: No internet connection required, so you can play smoothly anywhere, anytime. Perfect for Quick Breaks: Each game takes just a few minutes, ideal for killing time. ■ How to Play On your turn, place 1 to 4 cards face down following the numerical order (A → 2 → 3...). You don't actually have to have the right cards—lying is part of the game! If someone plays a card and you think it's suspicious, tap "Doubt!" within a few seconds. Catch your opponents' bluffs or be the first to empty your hand to claim victory!
