OK — have been messing about with this thing for about six months now and it’s stuck on my phone, reckon I’d write something up since a lad on another thread asked me a few days back. I’m UK based, mainly stick to footie and the horses, nothing mad, for context.

How I found it was actually embarrassing — I couldn’t ever work out what an e/w payout actually came to with 1/5 odds a place. I used to just eyeball it and moan when the payout landed. These days I punch the numbers in first, every time, even a simple single bet.

The single bet calculator is the bit I open most — you drop in stake and odds and it shows the return instantly, fractions or decimals. Same tool covers the multiples — acca and treble maths, lucky 15 and lucky 63, patents and yankees, and that’s where most people I know got it wrong. If you fancy a poke about, it lives at [url=https://singlebettingcalculator.uk/bet-calculator/lucky-63]how many bets in a lucky 63[/url] — free, no signup.

What really shifted things for me was the geekier tools. They’ve got an implied probability calculator which shows you what margin’s baked in, and a kelly criterion tool — I stick to fractional kelly because full kelly is terrifying. The dutching one gets used a fair bit when I’m spreading across selections.

Couple of gripes. The layout is pretty plain — zero frills, which honestly I don’t mind but some will. On my phone it’s usable but the lucky 63 breakdown make you pinch and zoom. Also there’s no proper app, it’s browser only — doesn’t bother me just flagging it.

Anyway. Costs nowt, barely any ads, does what it says. Anyone who honestly does the maths on paper, try it — it’s saved me a fair few dumb bets I’d have regretted.
