Gonggi
Also known as 공기 (Gonggi), Korean Pebble Game, Korean Jacks
A concentration game where players toss, catch, and transfer five pebbles through increasingly tricky sequences.
How to play
Collect five small pebbles (grape-sized) from the ground.
Scatter them on a flat surface.
Toss one stone up, grab one from the ground, and catch the tossed one before it lands, that's level 1. Level 2: toss one, grab two at once, catch.
Level 3: grab three, then four.
Level 4: grab all four at once.
Level 5: place all stones on the back of your hand, toss them up and catch as many as possible.
Players take turns; drop a stone and your turn ends.
First to complete all levels wins.
Keep it fair
If a stone rolls and stops on its own, it stays where it is, players can only touch stones on their own turn. Use this rule to prevent sneaky repositioning.
