Cards. 3 Rows. Absolute Chaos. Welcome to the Poker Puzzle That Fights Back.

Most puzzle games let you sit back and solve them at your own pace. Most mobile card games rely on randomized decks, microtransactions, or hidden information to keep you hooked. Sanshui: Poker Puzzle (三水) burns that entire rulebook to the ground. We have built an all-ages logic puzzle that demands speed, perfect tactical calculation, and the ability to adapt when the ground shifts beneath your feet. This is not gambling, and it is not a slot machine. It is a pure, unadulterated test of skill that takes the mathematical beauty of Chinese Poker and injects it with pure adrenaline.

The core of Sanshui is built upon the classic framework of Mậu Binh. At the start of a puzzle, you are handed exactly 13 cards. Your mission is to arrange those cards into three distinct scaling rows, which we call "waters." You must construct a 3-card front water, a 5-card middle water, and a 5-card back water. The unbreakable law of the board is that each row must be mathematically stronger than the one in front of it. Your back must beat your middle, and your middle must beat your front. If you misalign them, your entire hand fouls.

But Sanshui does not let you just solve the math in peace. The board is alive, and it is constantly changing. Enter the Tokens. Every single round, game-altering tokens rain down onto the board, aggressively mutating the rows they touch. A perfectly constructed hand can be ripped apart in milliseconds, forcing you to recalculate your entire strategy on the fly.

You will have to master the chaos. Adders will grant a water an extra card, breaking the standard mathematical limits and opening up wild new combinations. Blocks act as precision snipers, brutally removing the highest card in your row. Hazards are absolute disasters, instantly voiding an entire water and demanding immediate damage control. Spy and Swap tokens force a tactical trade of cards with your opponent, ripping away your safety net. And when you are completely backed into a corner, the Flush and Straight directives serve as emergency bailouts, entirely rewriting a struggling row.

Because every player receives the exact same odds on every token drop, there is zero unfairness. We have completely stripped away pay-to-win mechanics, card packs, and energy meters. More importantly, every single puzzle you encounter is checked by our engine to be 100% solvable. If you fail, it is only because you missed the critical path. An adaptive AI coach constantly monitors your performance, seamlessly scaling the difficulty from the Apprentice tier all the way to the brutal depths of Master Shen’s domain.

Choose your proving ground. Dive into Puzzle Mode for an endless, dynamically scaling challenge. Step into Timed Mode to race a ruthless clock, building your "Presence"—your longest unbroken solving streak—to dominate the global speedrunning leaderboard. Or face the ultimate trial in Shen Mode: survive a chaotic 10-second curse window before sprinting through a 35-second boss battle against Master Shen himself, scored mercilessly water by water.
