NEW — 3 AI Difficulty Levels Choose your challenge! Tiến Lên Tự Sắc now features 3 AI difficulty levels: Normal — Friendly AI bots for casual play. Perfect for learning Tiến Lên or enjoying a relaxing game. Pro — Challenge yourself against smarter AI opponents! In PRO Mode, the AI is cranked up — each opponent plays with its own personality profile, mimicking real human playing styles. One may aggressively chain combos, another may hold back and bait your strongest cards. Outsmart all three to prove you're a true Tiến Lên master! Expert (NEW!) — The ultimate AI challenge, powered by Monte Carlo Tree Search — the same technology behind AlphaGo and world-class poker AIs. This AI doesn't just follow rules — it simulates thousands of possible futures to find the perfect play, predicts what cards you're hiding, and finds winning moves that humans can't see. Do you dare to take on the strongest Tiến Lên AI ever created? Tu Sac (Tứ Sắc — Four Colors) is a popular Vietnamese game played with chess cards. Organize your hand into valid sets through melding and discarding. Known as Si Se Pai (四色牌) in Chinese. Catte (Cắt Tê) is a thrilling 4-player trick-taking card game. Each player is dealt 6 cards and must survive 6 rounds of strategic play. Win at least one trick in rounds 1–4 to avoid elimination, then battle it out in the dramatic face-up rounds 5–6. Save your best cards for last — the final round decides the winner! Xap Xam (Xập Xám — Chinese Poker) is a classic card game popular across Vietnam and Asia. Receive 13 cards and arrange them into 3 hands — Back (5 cards), Middle (5 cards), and Front (3 cards) — where each hand must be stronger than the one after it. Compare your hands against the AI opponent to score points. Master the art of balancing strong combinations across all three hands! Leaderboards & Scoring Race to 50: Be the first player to win a complete series. Each series victory earns you 1 point on the leaderboard.
