X01

In X01 darts you count down from 501 or 301 to exactly zero, three darts a visit, and the last dart has to hit a double. It is the game of every pub and every TV final. Sridu keeps score, calls every visit and lights up the way out on the board, one tile per dart.

  • Start on 101 to 1001, or any score you like
  • Double Out, Master Out or Single Out, with Double In as an option
  • The way out as tiles, updated after every dart
  • Legs, sets, teams and handicaps per player
  • Average, first 9, checkout rate and leaderboards

Anna needs 100, drawn the way the app shows it. The way out is T20 and D20, and the board lights up the treble. She only hits the single 20, so the app works out a new way straight away: T20 and D10. She follows it and checks out.

The rules

How a leg works

Everyone starts on the same score, usually 501, and players take turns throwing three darts a visit.

  1. Count downWhatever you score in a visit comes off your total, and the caller announces it. The maximum is 180, three treble 20s.
  2. Finish on a doubleWith Double Out, the standard, your last dart has to land in a double. The bullseye counts as a double, so you can finish 50 on the bull.
  3. Exactly zeroScore more than you have left and you bust. The whole visit counts for nothing and the next player is up.
  4. First to zero wins the leg501 takes at least nine darts, the perfect leg. Play a single leg, first to 3, or sets like on TV.

The rules

Bust

With double out you also bust if you leave exactly 1 or reach zero without a double. The darts rules explain why. Four example visits:

  • Left40Game shot
    1. D20Dart 1
    2. –Dart 2
    3. –Dart 3

    Exactly zero with a double.

  • Left40Bust
    1. 20Dart 1
    2. 20Dart 2
    3. –Dart 3

    Zero, but the last dart wasn’t a double. Back to 40.

  • Left40Bust
    1. T20Dart 1
    2. –Dart 2
    3. –Dart 3

    Over 40. Back to 40, and the remaining darts don’t count.

  • Left3Bust
    1. 2Dart 1
    2. –Dart 2
    3. –Dart 3

    You can’t check out 1 on a double. Back to 3.

If you bust with darts still in hand, the board shows the violet lock until you pull your darts. Anything you throw in the meantime does not count.

The way out, dart by dart

On 170 or less (180 with master or single out) the app shows how to check out with the darts you have left. There is one tile per dart, and the next target also lights up on the board. Miss it and you get a new way out straight away. Here is 57 in the three out modes:

  • Double OutDefault
    Left57
    Checkout · 2 dartsDouble Out
    1. Dart 117
    2. Dart 2D20

    The last dart has to be a double or the bullseye. 57 takes two darts: 17, then the double 20.

  • Master OutEasier
    Left57
    Checkout · 1 dartMaster Out
    1. Dart 1T19

    A treble finishes too, so treble 19 does it in one dart.

  • Single OutEasiest
    Left57
    Checkout · 1 dartSingle Out
    1. Dart 1T19

    Any segment finishes. On low scores the app picks the fat single, for 57 the treble 19.

  • Good doubles first. Among the shortest routes the app picks the one that ends on the best double: D20, D16, D18 and so on, with the bull last. So 57 becomes 17 and D20 rather than 7 and the bull.
  • No finish? If the darts you have left can’t get you out, it says No finish possible. With three darts in double out that happens on 169, 168, 166, 165, 163, 162 and 159.
  • Rather work it out yourself? Turn the help off under Settings, Throw suggestion. The caller can still announce what you need: “You require 40”.

Setup

Rules you can set

Choose X01 in the game setup, or tap 301, 501 or 701 directly on the X01 tile on the start page.

  • Starting score101, 201, 301, 501, 701, 901 or 1001, or Custom with anything from 2 to 9999. 501 is standard, 301 is quicker, and 701 or higher suits teams.
  • CheckoutDouble Out (the default): the last dart must be a double or the bullseye. Master Out: a double or a treble. Single Out: any segment finishes, which is easiest for beginners.
  • Double InOff by default. When it is on, your score only starts to drop once you hit a double. That double counts, and every dart before it scores nothing.
  • Fat BullOff by default. When it is on, the outer bull counts as the bullseye: 50 points and a double to finish on. See Fat Bull.
  • LegsOne leg, first to 2, first to 3, or any number up to 99.
  • SetsNone, first to 2, first to 3, or more. Each set goes to the first player to reach the leg target above, and then the leg count goes back to zero.
  • Who throws firstThe first player on the list, a bull-off or random. After that, each new leg starts with the next player.

Setting · Fat Bull

Fat Bull: the whole bull is worth 50

Switch on Fat Bull and the outer bull counts as the bullseye. Off by default.

  • StandardDefault

    The outer bull is worth 25. Only the bullseye scores 50, and only the bullseye finishes as a double.

  • Fat BullSoft-tip

    The whole bull counts as the bullseye: 50 points and a double to finish on, wherever your dart lands inside the outer ring. That is how soft-tip machines play it.

Fat Bull 501 has its own entry in the game search. Open Fat Bull 501 and Sridu switches the setting on for you. Handy if your group usually plays on a soft-tip machine.

Setup

Handicaps

Give each player their own X01 rules and a beginner gets a fair match against a strong player. Small tags on the score card show where a player’s rules differ from the game:

  1. Anna501
  2. Tim301301Single Out
  3. Lena501Double In
  • Their own starting score: the beginner plays 301 while the pro plays 501.
  • Their own checkout: Single Out for a child, Master Out or Double Out for everyone else.
  • Their own double in: switched on for the strong player only.

Leaderboards

Leaderboards and records

X01 matches count towards the leaderboards for average, highest finish, best leg, 180s and checkout rate. Only individual players get an entry, never bots or teams, and never with a handicap. The match also has to use the standard options from the setup screen, such as a starting score from the list. You can still play a custom score, it just won’t appear on the leaderboards.

Tips

Win more legs

  • New to darts? Start with 301 and single out, then move on to double out.
  • Leave yourself a good double. Hit the single on 32 or 40 and you are still on a double: D16 → D8 → D4. The way out tiles steer you there, and the checkout calculator shows what to leave from any score.
  • Legs are won on the finish. Practise with Checkout King and 121 under Training.
  • Club night: 501 double out, first to 3 legs, bull-off for the first throw. With more players, make it a tournament.
  • Remote play: an online match board against board, or a phone as a second screen. See Multiplayer.
