Bob’s 27

Bob’s 27 darts is Bob Anderson’s classic doubles drill. You start on 27 points and work round the board from double 1 to the bullseye. Hits add points, a round without one costs you, and at zero you are out. Before every dart, Sridu shows you what is at stake.

Round 7 at double 7, as the app shows it. Anna starts on 21, misses with a single 7, then hits two double 7s for +28. Ben is on 13, and a blank round costs him 14. After two misses his panel turns red: hit double 7 or you are out. He misses and goes out on −1.

The rules

How to play Bob’s 27 darts

You get 21 rounds of three darts, each round on a different double. The maximum score is 1437.

Start on 27Everyone starts on 27 points. Round 1 is double 1, round 2 is double 2, and so on up to double 20.
Every hit scoresEach dart in the round’s double adds its value, so double 7 is worth 14. Hit it three times and you get 42.
A blank round costs youIf none of your three darts lands in the double, its value comes off your score once. Singles and trebles of that number count for nothing.
At zero you are outDrop to zero or below and your game is over. Round 21 is the bullseye, worth 50. The highest score after that wins.

In the game

You always know what is at stake

Bob’s 27 tests your nerve on the doubles. Here is what you see during a game:

The current double lights up on the board, just its ring. In the last round it is the bullseye.
Every dart gets a label: “+14” in the double, “off target” anywhere else, including the single and treble of that number.
What a miss would cost shows in the panel until your first hit. On your last dart it turns amber, or red if a miss would put you out.
All 21 doubles in a row sit under the panel. Each hit gets a dot, points won show in green and points lost in red, with the current double highlighted. Next to the row you see your hit rate and how far you lead or trail the best of the others.
Three hits in a round get their own callout. When you go out, a big “Out” appears, your card shakes and the others play on.
The caller announces each double and how many hits you got in the round.

Scoring

What one round can do

Three ways the same round can go. You are on 21 points and throw at double 7, worth 14:

No hit0/3
1. 7off target
2. D19off target
3. T7off target
21 → 7
A round without a hit costs the value of the double once, no matter how close the darts were.
One hit1/3
1. 7off target
2. D7+14
3. D16off target
21 → 35
One hit makes the round safe. The misses cost nothing.
Three hits3/3
1. D7+14
2. D7+14
3. D7+14
21 → 63
Every hit scores. Three in one round get the big callout: 3 × D7.

Setting · Order

Which double comes next

You always play all twenty doubles with the bullseye last. Only the order changes:

D1 → D20Default
1. 1
2. 2
3. 3
4. 4
5. 5
6. 6

8. B
The classic: the small doubles first, where a miss costs little but the 27 runs out fast.
D20 → D1Big first

2. 19
3. 18
4. 17
5. 16

The big doubles first. A hit on double 20 is worth 40, but a blank round costs 40 and you are out straight away.

A new order every game, the same for all players. You never know which double comes next.

Setting · What a miss costs

Per round or per dart

Good players can find the classic too forgiving. Here are the same three darts at double 7, again from 21 points:

Per roundDefault
1. 7off target
2. D7+14
3. D16off target
21 → 35
The classic. One hit makes the round safe and the misses cost nothing. Only a blank round costs the value of the double.
Every dartHarder
1. 7−14
2. D7+14
3. D16−14
21 → 7
Every missed dart costs the value of the double. The same three darts now lose 14, so you need two hits out of three to gain anything.

Who wins

Placings with more players

Everyone gets a clear place, even when some players are out or level on points:

Still in beats out
1. Anna49Winner
2. Cara12Second
3. BenOut at D7Third
4. DanOut at D5Fourth
The highest score wins. Anyone who is out ranks behind everyone still in, and going out later beats going out earlier: Ben lasted longer than Dan.
A tie
1. Anna85 · 9 doublesWinner
2. Ben85 · 7 doublesSecond
Level after the last round? Then whoever hit more doubles wins, not whoever happens to be first on the list.

Tips

Stay in longer

The early rounds matter most. The small doubles are worth little, but miss the first five and you are out on double 5.
One hit makes the round safe. Keep aiming at the same double with your remaining darts, because every extra hit adds more.
Watch for red. A red panel means a miss ends your game. Take your time over that dart.
Learn with play on. Use play on until you can get through all 21 rounds, then switch to the classic.
Too easy? Make every dart count. Once you survive the classic every time, switch the penalty to every missed dart and try to stay above zero.
Chase your record. You see your hit rate during the game, and the statistics keep your best and worst scores.
Every double in one total. The JDC Challenge gives you one dart at every double and the bull, between two rounds of Shanghai.
