I've been on Single Bet Calculator for the best part of a year, mostly on my phone, so this is just my two pence. Came across it off another forum thread, wasn't an ad.
The lobby is genuinely huge — a bit over 3,500 slots last time I counted. Play'n GO stuff dominates, so Sweet Bonanza and the usual suspects are present and correct. I tend to live on Big Time Gaming megaways out of pure habit. Small annoyance — searching for a specific slot at Single Bet Calculator is more faff than it should be, I usually just scroll and hope.
Live tables are Evolution-run, which is fine by me. Real croupiers, the stream holds up on 4G, and Crazy Time is rammed on a Friday. Fair to note the British tables are properly staffed from about 6pm onwards. If you're weighing up the promos I'd have a nose at <a>single calculator bet</a> rather than taking my word for it.
The sign-up deal at Single Bet Calculator was a 100% match to ?150 with 50 spins. Wagering is 40x nothing special but not predatory. There was a ?5 no deposit token when I registered. Minimum is a tenner, sign-up took me maybe five minutes, KYC took a day.
Payouts have been fine. Visa and Mastercard land in a couple of days, e-wallets were same-day for me, and crypto is quickest if you use it. Pulled ?180 out on Tuesday and it landed early. The live chat on Single Bet Calculator was on me within five minutes — copy-paste at first but fine after. Licence is UKGC, which matters more than the bonus size. No standalone app, the browser version does the job.
