About This Game

Recess at a 2000s Korean elementary school, in a classroom with a reed organ and dictation notebooks. Gonggi is the Korean game of jacks: toss one stone up, pick up stones from the desk while it's in the air, and catch it as it falls.

Scatter, toss, pick up and catch with just the left click.

Hold, sweep your hand and let go to scatter the stones. The faster you sweep, the wider they spread. Click while the tossed stone is in the air to pick up, and bring your hand under a falling stone to catch it.

Never played gonggi? Four lessons is all it takes.

Learn step by step, from tossing and catching to Twosies. If you get stuck, the stones stay in the air a little longer, and your seatmate can show you how with your own hand. Set the hang time, catch window and scatter help yourself before each round.

First to the agreed number of years wins. The loser gets flicked on the wrist.

Rock-paper-scissors decides who goes first, then you take turns. In the last stage, the Flip, you catch the stones on the back of your hand and snatch them, and every stone you snatch earns a "year". Get there first and your opponent still gets one last turn; if you both make it, it's deuce. You can also play a Steam friend 1-on-1 online, and you get a certificate at the end.

Every class has its own rules.

Stones that fall faster, a class played with pebbles: every grade has six classes like these. Clear a class and pick one of three gifts from your classmates, like an eraser that rubs out one mistake or a bandage that gives you an extra chance. Finish Grade 6 to unlock random class runs.

Get up from your chair and wander the classroom and the playground.

There are more than 70 things to touch. Play the reed organ, race a toy car, tap the fishbowl, focus sunlight with a magnifying glass, ride the swings. In a room with a friend, you share them.

Peel a sticker, stick it on, and it's on.

Peel off hair, clothes, hat and glasses stickers and stick them on. Hover over one to try it on first, and you can dress your seatmate the same way. Stick hearts or stars on the backdrop, and when you're done, a snapshot goes into your notebook.

Write on the chalkboard, in notebooks and in a sketchbook, all with the mouse.

At the chalkboard you get chalk in four colors and a board eraser, and you clean the eraser in the eraser cleaner. Write in your dictation notebook with pens from your pencil case, and draw in a 16-page sketchbook with 24 crayons. Your drawings stay. The name you enter the first time is written stroke by stroke with a marker, and it goes on your name tag and certificates.

• Four kinds of stones: glitter, hexagon, pebble and eraser bits
• Three places to play: a classroom desk, the floor at the back of the classroom and the playground
• Practice: repeat any stage you choose, with no lives
