Six curves · one arena · sixty ticks a second
Curve2gether is a free multiplayer curve game for six players on six phones. Steer a curve that grows behind you. Touch any trail, yours included, and your round is over. Last one still turning takes the point.
Thirty seconds, cut from rounds the game actually played — seeds 20260922 and 20260931, six bots, nothing staged. Starts muted; the sound is the game's own music.
Hall of fame
Ranked by the longest single round anyone survived, and it empties every Monday. An all-time table is won once and then stops being something anyone can enter — someone arriving in month three should still be able to get on it. Rounds with fewer than two people don't count: surviving five bots for four minutes is a fine afternoon and not a record.
The board is in the game as well, under You — and this is the same twenty rows.
Top twenty of the current ISO week, UTC. Names are two indices into two fixed lists of 128 words; this page renders them from the same table the game does, and shows a row unnamed rather than misnamed if the two ever disagree.
The only control
Hold the left side of the screen to turn left, the right side to turn right. Let go and you go straight. Your curve is turning or it isn't. All the skill is in when.
The only way through
That leaves a hole behind you, and holes are the only openings in a board that keeps filling up. A hole is 15.4 units of arena. Your head is 4. Take a collision radius off each edge and you have 7.4 units to aim at, at 84 units a second.
Ways to play
Six seats, six people, six phones. No passing one device around, no split screen. Bots take any seat nobody claims, and anyone past the sixth can watch on the same code.
Matched with whoever is queueing. Bots fill the empty seats instead of making you wait.
Read one code out loud. Everyone who types it lands in the same room.
Four tiers, offline. Plus a daily round on one seed, the same for everyone.
The same code, without taking a seat. Live, from the seventh person onwards.
What it doesn't do
The short version of the privacy policy. The full one takes a minute to read.
Get it
Same game, same server, same rounds. A tab, or an icon from either store, and the three of them meet in the same match.

Curve2gether is a free multiplayer curve game for up to six players, one phone each. Everyone steers a curve that moves forward at 84 units a second and draws a trail behind it. Touch any trail, your own included, and your round is over; the last curve still turning takes the point.
Nothing. There are no ads, no in-app purchases and no paid tier: nothing is sold inside the game, and nothing is sold about you.
No. app.curve2gether.com is the whole game in a browser — same server, same rounds, and the same players as the phone builds. The Android and iPhone builds are free on Google Play and the App Store, for anyone who would rather have an icon than a tab.
One person opens a room and reads out its six-character code; everyone who types that code lands in the same match. There is nothing to sign up for and no friend list. Seats nobody claims are taken by bots, so a room of two people is still a full arena.
Six people play and everyone else can watch. The host shares the same six-character code as a watch link, and whoever opens it sees the match live — the real arena, not a recording, and a few hundred milliseconds behind the players. Watching takes no seat, so a group of ten still all end up in the same game.
Yes. In a browser the left and right arrow keys are the same control as the two halves of a touchscreen: hold one to turn that way, let go to go straight.
Yes. Four tiers of AI opponent — Rookie, Casual, Sharp and Ruthless — run entirely on your own device, alongside a daily round on one seed that is the same for everyone. Only online matchmaking needs a connection.
No account, no email address and no advertising ID. A generated device id and your round results are stored so the weekly board can be built, and one button in settings deletes every row you own from the server. This page loads no third-party fonts, scripts or pixels either. The privacy policy is the long version.
