Halve It (Le Capital) rules

Halve It is the darts game where every round sets you a target and missing it cuts your score in half. Throw plays the French version, known as Le Capital: the classic number rounds are mixed with trickier challenges (three colours, exactly 57, a diagonal through the bull) and players can place secret bonus bets.

The goal

Finish the last round with the highest total. The CAPITAL round builds your starting score, then every round adds to it or eats into it.

The rounds

Each player throws 3 darts per round. Darts that meet the round's target score their normal value, the others score 0.

#	Round	What counts
1	CAPITAL	The whole board.
2	20	Only darts in the 20.
3	3 COLOURS	Three different colours with your three darts.
4	19	Only darts in the 19.
5	3 IN A ROW	Three consecutive numbers (e.g. 4, 5, 6), any order, trebles excluded.
6	18	Only darts in the 18.
7	TREBLE	Only trebles.
8	17	Only darts in the 17.
9	57 POINTS	A total of exactly 57.
10	16	Only darts in the 16.
11	DOUBLE	Only doubles (bullseye included).
12	15	Only darts in the 15.
13	3 SIDE BY SIDE	Three neighbouring segments on the board (e.g. 20, 1, 18), trebles allowed.
14	14	Only darts in the 14.
15	DIAGONAL	One bull + two numbers opposite each other on the board (e.g. 20 and 3).
16	13	Only darts in the 13.
17	BULL	Only the bull (25 or 50).
18	TREBLE 1	Optional. Each treble 1 is worth your CAPITAL round score.

A few details:

Number rounds: single, double or treble of the number, at face value (a treble 20 is 60).
Whole-visit rounds (3 COLOURS, 3 IN A ROW, 57 POINTS, 3 SIDE BY SIDE, DIAGONAL) are judged on all three darts together. Make it and you score your visit's total. Miss it and you score 0.
Colours: singles are black or white, doubles and trebles red or green, the bullseye red and the outer bull green.

Miss a round, lose half

A round where you score 0 is a fail. What happens depends on the rule you pick:

Halve (default): your total is halved on the spot (rounded up).
Classic: nothing changes during the game, but fails are counted at the end. By default 3 to 4 fails cost 100 points and 5 or more cost 200. Thresholds and amounts can be adjusted.

Secret bonus bets

Before the game, each player secretly picks one round to bet on (you pass the phone around). Once everyone has played that round, the bet is revealed:

if the player who bet on it posts the best score of the round, on their own, that score is multiplied (x2 by default, x3 as an option);
with bonus stealing (on by default), if someone else posts the best score on their own, they grab the bonus instead;
on a tie for the best score, or if nobody scores, the bonus is lost.

In team play, a teammate of the player who bet also gets the bonus.

With Throw

Your phone films the board and judges every round by itself: it crosses out darts that miss the target and waits for the third dart before judging a whole-visit round. A misread dart is fixed with a tap on its slot. From 1 to 8 players, solo or in teams.
