How the chase works
You pick a team that draws a lot and bet on a draw in every one of its matches. After a loss the next stake is bigger: big enough for a win to cover all the past losses and bring one more unit. Sooner or later the draw comes, and then you are in profit. It is the martingale, only on draws.
It sounds safe: roughly one match in four is a draw, and a run without draws cannot last forever. True, not forever — but longer than the bank can hold out.
How the stake grows
At odds of 3.51 the first stake is 0.40 units. After five misses the stake is already 2.1, after ten it is 11.4, and by then 27.6 has been lost in total. All that to win one unit.
How long runs without a draw last
On average a team's run without a draw lasts 2.7 matches. But 21% of runs stretch to 5 matches or more, and 4.4% to 10 or more. The record in the database is 32 matches in a row without a draw.
What history shows
We ran the chase on every team: 38 matches in a row (about a season), with a bank of 100 or 1,000 units, at an average bookmaker's odds.
| Bank | Seasons | Went bust | Average result | Per unit staked | Biggest stake |
|---|---|---|---|---|---|
| 100 | 1,929 | 11.1% | −3.2 | −6.1% | 40 |
| 1,000 | 1,929 | 0.8% | −3.4 | −4.5% | 319 |
With a bank of 100, 11.1% of seasons end with the bank gone: the next stake simply no longer fits in it. With a bank of 1,000 going bust is rare (0.8%), but the stake reached 319 units — to win one. And in both cases the average is a loss: −6.1% and −4.5% per unit staked. It is the same margin, just collected differently.
What if the model picks the draw?
This is how the model runs the draw martingale live in Premium: every day it takes the match where it sees the highest chance of a draw, with a bank of 100. Over 937 days of history that gave 287 winning chains of one unit each and 1 busted bank; the longest run was 14 misses in a row. The result: a gain of 115 units.
But there is no edge here. Draws in the chosen matches came in 30.6% of the time, while the odds implied 32.1%: each bet on its own was a losing one. A bank of 100 units is gone after 12 misses in a row, and with draws this frequent you would expect about 4 busted banks over this period. In fact there was 1 — that is luck: the next long run of misses simply has not come yet.
The draw martingale in hockey
In hockey the martingale is played on the draw after regulation time: after 60 minutes 22.4% of matches were level, at typical odds of 4.15. Fewer draws and higher odds mean longer losing runs. We ran the martingale on every team in stretches of 40 matches in a row.
| Bank | Stretches of 40 matches | Bank burnt | Per unit staked | Biggest stake |
|---|---|---|---|---|
| 100 | 153 | 7.8% | −2.1% | 24 |
| 1,000 | 153 | 1.3% | −10.2% | 236 |
The record is 31 matches in a row for one team without a draw after regulation. Betting the draw in every match gave −4.4%; the martingale does not fix that result, it only reshapes it into frequent small wins and a rare bust.
Why this happens
- Chasing does not change the chance of a draw or remove the margin: each bet on its own is a losing one.
- It only changes the shape of the result: lots of small wins and a rare but huge loss.
- Banks and betting limits are finite: the longer the run, the sooner the stake hits the ceiling.
