Store description excerpt

Kei-Yen: Manipur's Ancient Strategy Game Long before smartphones, cattle grazers in the valleys of Manipur passed their afternoons drawing a board on bare earth — using pebbles as Tigers and small sticks as Roosters. This is Kei-Yen: a game of ambush, sacrifice, and cornering, passed down for generations in a land where storytelling, music, and play have always been woven into daily life. The Land of Jewels Manipur — meaning "Land of Jewels" — is a small state tucked into the hills of Northeast India, bordering Myanmar. Home to the Meitei, Naga, and many other communities, it holds one of the richest and least-known cultural landscapes in South Asia: the classical Manipuri dance form, the martial art of Thang-Ta, the sport of Sagol Kangjei (the origin of modern polo), and a deep oral tradition of folk games like Kei-Yen and Machin Manao. This app is a small window into that world. The Sound of the Pena As you play, you'll hear the haunting, string-and-bow tones of the Pena — one of Manipur's oldest musical instruments, traditionally used by wandering minstrels called Pena Khongba to narrate legends, royal chronicles, and moral tales through song. Made from a bamboo rod, a coconut-shell resonator, and a single string, the Pena's sound has accompanied Manipuri storytelling for centuries. It plays softly in the background here as a quiet tribute to that oral tradition — the same spirit of passing down stories and games from one generation to the next that inspired this app. Preserving a Vanishing Tradition I traveled to Andro village, Manipur, where locals still keep this tradition alive, and played Kei-Yen with elders at the Andro Museum to understand the game firsthand. Like many indigenous board games, Kei-Yen is slowly being forgotten by younger generations. This app is my effort to document and restore it — digitally — before it's lost. How to Play: Tiger vs. Rooster Roosters (Yen) move to adjacent points, working together to block every Tiger from moving. Trap all Tigers, and the Roosters win. Tigers (Kei) leap over Roosters to capture them. Capture 8 Roosters, and the Tiger wins. Roosters start positioned in packs of four across the board, giving the flock a numbers advantage — but Tigers strike with speed and reach. A Real Strategy Engine, Not Just Random Moves Kei-Yen runs on a genuine game-playing AI — a Minimax algorithm with Alpha-Beta pruning — the same family of algorithms used in chess engines. To keep it fast even on older, low-spec Android phones, the entire move-generation core is written using low-level bit manipulation (bitmasking and bit-shifting) instead of heavier data structures. This lets the engine search far more positions per second with minimal memory overhead — so the AI feels genuinely intelligent without draining your battery or lagging on budget devices. Features Human vs. Human — pass-and-play locally. Human vs. AI — challenge the engine at your own pace. AI vs. AI — watch two strategies clash. Ambie
