A free 3D board on a lawn, with video chat. Four bags each, cancellation scoring, first to 21 — or play the AI when nobody's around.
Cornhole — bean bag toss, corn toss, whatever it's called where you are: fabric bags thrown at a slanted board with a hole near the top. Kosmi gives you one for two people who already know each other. You make a room, you send a link, and whoever takes the other seat is the one you invited.
Video and voice chat run inside the room, with each player's camera beside the court. Everyone else in the room can watch and heckle, eight of them on camera around it.
The court runs in the browser, on a laptop or a phone. Your friend opens the link and sits down — no app, no account.
Press Play against AI and Kosminaut takes the other seat. It picks real throws — slide it in, airmail it, block the front of the board, knock yours off — and throws like an arm, not a machine.
Grab the bag, drag it where you want to throw from, and flick. Direction is your aim, flick speed is your power, and the arc is fixed. Flick too gently and you've just put the bag down.
They land, slide, tilt with the deck, knock each other about and drop through the hole. Push your opponent's bag in and it counts for them — knock your own off and that's on you.
When the match ends, the same room does watch parties, pool, mini golf, shuffleboard, poker, card games and retro consoles. You don't have to move anywhere.
If you've never kept score at a cookout, this is the bit worth reading.
You each get four bags a round, thrown one at a time, alternating. A bag through the hole is 3, a bag that stays on the board is 1, and a bag on the grass is nothing. Bags that get knocked off, or that never made it up, are dead for the round.
When all eight are down, the round is scored by cancellation: the two totals cancel out and only the difference counts, to whoever had more. Score 5 against their 3 and you take 2, not 5. Score the same and nobody takes anything — which is why a late bag that knocks one of theirs off is worth as much as one of yours going in.
Then the next round starts. The player who scored throws first, which means the one who got nothing keeps the hammer — the last bag, and the chance to undo the whole round with it. First to 21 wins.

Create a Kosmi room with the cornhole court in it, send your friend the room link, and take a seat each. The match starts by itself the moment both seats are filled — no account needed to join, and nothing to install on any device.
A lawn game, also called bean bag toss or corn toss. You throw fabric bags at a slanted wooden board with a hole near the top. A bag through the hole is worth 3, a bag that stays on the board is worth 1, and a bag on the grass is worth nothing. First to 21 wins.
Cancellation scoring. At the end of each round the two players' points cancel out, and only the difference goes to whoever had more — so if you score 5 and your opponent scores 3, you get 2 and they get nothing. Equal totals score nothing at all. First to 21 wins, or 11 if the room admin sets it.
Yes, completely. The court, the video chat and the room are free, and there's no limit on how many matches you play. Kosmi Premium exists for other things, but nothing about the cornhole game is paywalled.
Grab the bag in the pitcher's box, slide it to where you want to throw from, and flick. The direction of your flick is the aim and the speed of it is the power. The arc is fixed, so there's nothing else to learn — and a flick that's too gentle just puts the bag down instead of throwing it.
The board is: 48 by 24 inches, with a 6 inch hole 9 inches from the back. The court isn't. There's one board rather than two, both players throw from the same end, and it's 18 feet rather than 27 — a camera can just turn round instead of you walking to the other end, and 18 feet is a distance a phone flick can actually hold, which is what most backyards play anyway.
Yes. Sit down and press Play against AI, and Kosminaut, the room's AI companion, takes the other seat. It picks from real throws — slide it in, airmail it, block the front of the board, push our bag in, knock theirs off — and throws like an arm rather than a machine, so it misses often enough to be worth beating. You can also throw around an idle court on your own while you wait.
Yes. Video and voice chat are built into the room, so both players are on camera beside the court, and everyone else in the room can watch and talk — up to eight of them on camera around it.
Yes. On a phone the court runs up the screen with the pitcher's box at the bottom, so a throw always goes upward under your thumb. Guests join straight from the room link without signing up.
