2 player Tron: send a friend a link, race them now
Most two-player Tron games online either need both of you on the same keyboard or haven't worked since Flash died. CUTOFF is built for playing someone who isn't in the room: you send a link, they open it, and you are both on the grid.
CHALLENGE A FRIENDHow to start a duel
- Open CUTOFF and press challenge a friend.
- Send the link however you like — WhatsApp, Discord, Instagram, a text.
- The moment your friend opens it, the countdown starts. No sign-up for either of you.
Why it feels fair even with lag
Online Tron is unforgiving: one late turn and you're in a wall. CUTOFF uses rollback netcode — both players share one world that is a pure function of the arena and everyone's inputs, so when an input arrives late the game rewinds, applies it at the right moment and replays, instead of teleporting anyone. Moves resolve simultaneously each tick, so there is never a “who moved first” — if you both hit the same cell at the same time, it's a draw and the round is replayed.
After the match
- Rematch in one tap, straight from the result screen.
- Head-to-head record — the game remembers who is up in your rivalry.
- Spectators — anyone with the watch link can see it live.

Can we play on different devices?
Yes. One of you can be on a phone and the other on a laptop.

No. Neither player needs an account for a friend duel.
Is there a local two-player mode on one keyboard?
Not right now — CUTOFF is built for online play, where each player uses their own device.
