OK — have been messing about with this thing for about four months now and I keep coming back, reckon I’d chuck my thoughts in since a mate asked me a few days back. Am based in the UK, generally do football and horses, nothing mad, for context.

The reason I started using it was genuinely pretty stupid — I never could work out what an e/w payout actually was when the place terms changed. I used to just eyeball it and moan when the payout landed. Now stick my stake in first, every time, even a straight one-selection punt.

Their single bet calculator is the one I’m on daily — you drop in your stake, the odds and it spits out profit and total return with no faffing, fractions or decimals. Same tool covers the multiples — trebles maths, lucky 15s, a yankee, honestly that’s where I always got it wrong. If you want a look, it’s over at [url=https://singlebettingcalculator.uk/bet-calculator/kelly-criterion]half kelly calculator[/url] — free, no signup.

The thing that actually shifted things for me were the more serious extras. The probability calculator that shows what margin’s baked in, and there’s the kelly staking calculator — I use half kelly as the full version is terrifying. The dutch tool is handy too when I’m spreading across selections.

Couple of gripes. Its design looks pretty plain — not much polish, it’s clearly function over form. On mobile it works but the lucky 63 breakdown make you pinch and zoom. Also there’s no app, it’s browser only — slight shame but worth saying.

So yeah. Free, barely any ads, does the job. If anyone even now does the maths on paper, have a look — saved me a load of dumb bets I’d have regretted.
