Where It Comes From

Gonggi (곡기), sometimes called Korean jacks or ojaknori, is a traditional children's game played with five small stones or plastic pieces called gonggitdol. It's been a schoolyard and living-room staple in Korea for generations, similar in spirit to jacks or fivestones played in other countries, but built entirely around a single hand's dexterity rather than a bouncing ball. Kids have played it on classroom floors, sidewalks, and grandma's living room mat for decades, and it saw a fresh wave of global attention after Squid Game Season 2 featured it as one of its game-show trials in late 2024, sending curious fans everywhere searching for the rules.

How It's Officially Played

The core version uses five small stones scattered on a flat surface, and it's played in escalating levels. In Level 1, a player tosses one stone into the air, quickly scoops up one stone from the ground with the same hand, and catches the falling stone before it hits the ground, all without dropping anything or touching a stone you're not supposed to. Level 2 repeats the process but requires picking up two stones at a time, Level 3 ups it further, and so on until, in the final level, a player tosses all five stones up at once and must catch as many as possible on the back of their hand before flipping them and catching them again in their palm. Miss a catch, touch the wrong stone, or fumble the toss, and it's a "dead" turn, the stones pass to the next player. On variety shows, idols usually play a speed-round or head-to-head version: whoever finishes all the levels first, or racks up the most successful catches within a time limit, wins, while the rest sit there wincing in secondhand nervousness.

Fun Twists Idols Add

Idol variety loves stripping gonggi of its quiet-classroom vibe and replacing it with maximum pressure. Producers frequently turn it into a straight elimination duel: two members face off stone-for-stone, and one dropped catch means instant defeat and a punishment, rather than just passing the turn like the traditional rules allow. Some segments swap the tiny stones for oversized or awkwardly shaped props to make the catches harder and funnier to watch, and others add a strict time cap so members are rushing through levels they'd normally take slow and careful.

It's also become a favorite "hidden talent" reveal, plenty of idols who look effortlessly cool on stage turn out to have genuinely elite gonggi hands from childhood, and the show milks every second of the crowd's shocked reactions when someone breezes through all five levels without blinking.

How to Play It at Home

You don't need actual gonggi stones to run this one, small pebbles, dice, buttons, or even wrapped candies work fine, as long as you've got five roughly similar-sized pieces that fit comfortably in one hand.

Grab five small objects and clear a flat surface, a table or hard floor both work. Scatter all five pieces in front of you. For Level 1, pick up one stone, toss it straight up, quickly grab one more stone off the surface, and catch the falling stone with the same hand before it lands, all in one smooth motion. If you drop anything or fumble the catch, your turn ends and it passes to the next player. Once you clear Level 1, move to Level 2: same process, but now scoop up the remaining stones two at a time instead of one. Keep progressing through the levels (picking up three, then all remaining stones) until someone completes every stage. For a shortcut version that's easier for beginners, just play "most successful catches in 60 seconds" and skip the escalating levels entirely.

For a home game night, play it as a head-to-head duel like the shows do: two people go stone-for-stone, and whoever fumbles first is out. Keep the stakes light and fun, the loser does a silly forfeit like an impression of someone in the room, sings a chorus a cappella, or has to eat the next bite of dessert with chopsticks only. It's a great quiet-round palate cleanser between louder party games, since everyone ends up huddled around watching one pair of hands anyway.

Watch It In Action

Five stones, one shaky hand, and a room full of people holding their breath, gonggi proves you don't need chaos to make great variety TV, just something small enough to drop and a member who really, really doesn't want to be the one who drops it.
