So — been on this thing for about a few months now and I keep coming back, so figured I'd say something since a mate asked me last week. Am UK based, mostly stick to footie and the horses, small stakes, just so you know where I'm coming from.
The reason I started using it was honestly a bit daft — I couldn't ever get my head round what an e/w payout would be once you get five places instead of three. Basically I'd guess and then be surprised. Now punch the numbers in first, every time, even a simple single bet.
The single bet calculator is the one I open most — you drop in stake and odds and it spits out returns instantly, fractional or decimal, doesn't matter. Same tool covers the multiples — trebles maths, a lucky 15, patents and yankees, honestly that's where I always got it wrong. If you fancy a poke about, it's here <a href=https://singlebettingcalculator.uk/bet-calculator/trixie>trixie calc</a> and there's no login wall, which I appreciated.
One thing that actually made a difference is the geekier extras. There's an odds-to-probability converter that shows the overround, and there's the kelly criterion calculator — I stick to fractional kelly since full stakes are a quick route to a dead bankroll. Dutching calculator gets used a fair bit when I'm spreading across selections.
It's not perfect mind. The interface looks a bit basic — no flash, which honestly I don't mind but some will. On mobile it's fine though the acca grid are a squeeze. And no app, it's browser only — fine by me but worth saying.
Anyway. Free, barely any ads, does the job. Anyone who still adds it up in their head, have a look — saved me a fair few dumb bets I'd have regretted.
