Darts 301

Five, including whoever starts the game. Everyone plays from their own device and sees the same board and the same scores at the same time.

No. One player creates a room and gets a five-character code. Anyone who types that code into the same page joins the game. Nothing is stored and no account exists.

Tap the board where you want the dart to land. A ring appears and pulses in and out around that point — tap again to release. The dart lands somewhere inside the ring, so the tighter the ring is when you let go, the closer you land to what you aimed at. Arrow keys and the space bar do the same job without a mouse.

A dart that would take you below zero, or leave you on exactly one, or land you on zero without a double when double-out is on. Your score goes back to where it was at the start of the turn and the darts pass on. It is the rule that makes the last few points the hard part.

By default yes, which is how 301 is normally played: the winning dart must land in a double or the bullseye. The host can turn that off in the lobby for a quicker, friendlier game.

When your score can be finished with the darts you have left, DO101 shows one way to do it — 170 as T20, T20, Bull, for instance. It is a suggestion, not a requirement, and it quietly disappears for scores like 169 that cannot be checked out at all.

Only while the host's tab is open. There is no database holding rooms — close the tab and the room is gone, which is also why nothing about your game is stored anywhere.

Some corporate firewalls and mobile networks block the peer-to-peer traffic WebRTC needs. DO101 tells you plainly when that happens instead of pretending someone has joined.
