Description
げまじゃん (Gemajan) is the kind of quick‑fire card showdown you pull out when the group wants a laugh and a little competition without the rule‑book marathon. Designed by Kamomeno Jona in 2026, this 3‑to‑7 player romp runs in 5‑20 minutes, so you can squeeze several rounds into a coffee break or a night‑in. The magic lies in its blend of ladder‑climbing and good‑old rock‑paper‑scissors, all wrapped in simultaneous action selection and a dash of trick‑taking. You’ll pick your card in secret, reveal at the same time, and watch the hierarchy shift as players leap up or tumble down the ladder. The rules are so simple you can teach a newcomer between sips, yet the tension of guessing opponents’ moves keeps every round fresh. Perfect for parties, game nights, or any time you need a fast, funny, and totally addictive card game that gets everyone shouting, “I’m gonna win this round!”
