So — been using this thing for something like six months now and it's stuck on my phone, so thought I'd say something since a lad on another thread asked me the other day. I'm based in the UK, generally stick to footie and the horses, nothing mad, so take it how you like. What got me on it was genuinely embarrassing — I couldn't ever work out what an each way return actually came to once you get five places instead of three. I'd just wing it and moan when the payout landed. Now stick my stake in before I place anything, even the boring singles. Their single bet calculator is the bit I'm on daily — you put in your stake, the odds and it shows the return instantly, either odds format. There's also the multiples — trebles maths, lucky 15s, yankees, and that's where I always lose track. If you want a look, it lives at accumulator calculator and there's no login wall, which I appreciated. The thing that genuinely shifted things for me was the geekier extras. The implied probability calculator which shows you how much the bookie's taking, and there's the kelly criterion calculator — I stick to fractional kelly since full stakes are terrifying. The dutch tool is decent if I'm spreading across selections. It's not perfect mind. Its interface looks pretty plain — not much frills, which honestly I don't mind but some will. On mobile it works but the bigger tables are a squeeze. And no proper app, just the site — fine by me just flagging it. Right, that's me. Free, not plastered in adverts, does what it says. If anyone still works out returns on a calculator app, have a look — it's saved me a load of "wait, that's it?" moments.
