London dartboard master-in, double-out checkouts

Checkout tables for master-in, double-out darts games with the London dartboard

Introduction

This part of the darts > Tables > HTML project provides checkout tables for darts games with the London dartboard played in master-in, double-out mode. These tables are valid for games where the first (in) dart must land on a double or a triple, and the last (out) dart must land on a double.

In double-out games with the London dartboard, the last dart can score between 2 and 50 points. The last two darts can reach 110 points, and 170 points can be scored with the last three. After a double or triple has been thrown, the extensive any-in, double-out checkout tables apply to these scores.

As for master-in, double-out checkouts, the following can be observed. Darts games commonly require players to score x01 points, where x is an integer. The following table shows the required number of darts to reach such scores in London dartboard master-in, double-out games. In addition, the corresponding number of possible checkouts is shown.

Score	Darts	Checkouts
101	2	1
201	4	73
301	6	15,645
401	7	56
501	9	3,944
601	11	3,658,161
701	12	286
801	14	38,740
901	16	202,771,392
1001	17	816

The most exciting games will be those with relatively few possible checkouts. Checkout tables for these scores are given below. A checkout table for 501 points was included as it is a typical score in darts games. Additional tables can be generated using the darts toolbox of the darts project.
