Kamayuu — A Game of Memory & Nerve

Kamayuu is a card game built entirely around memory, position tracking and nerve. Every player keeps four cards face down in four fixed positions. At the deal, only your bottom two are revealed to you — the rest you have to remember, or forget at your own risk. Draw, swap, and match discards to lower your hand, then decide when the moment is right to buzz.

On your turn, draw a card and either slot it into one of your four positions, discarding what you removed, or discard the draw outright. You can also take the public discard pile's top card and swap it into a position, unless you were the one who just discarded it. During any player's turn, anyone can throw a match: tap a card you believe shares a rank with the top discard. A correct match costs nothing; a wrong one reveals your card to the table and adds a penalty card to your board. Red Jacks let you peek at one of your own cards. Red Queens let you compare a card of yours against an opponent's and choose whether to trade. When you believe your hand adds up to the lowest total at the table, buzz — every other player gets one final turn, then all hands reveal and the lowest total wins.

Kamayuu is free to play online at kamayuu.builtbygsv.in with no download or installation. Play Practice mode solo against 1-3 AI opponents on easy, medium or hard difficulty, or open a Private Table to get a six-character room code and play online with friends. Quick Match, for pairing casually or competitively with strangers, opens once enough people are playing.
