OK Jackpot Party... I'm being totally honest here.
Very disappointed. Deposited £100, got £100 free = £200 starting balance.
Money went down very fast on £0.75-£1.00 bets. Bonuses rounds ALWAYS revealed COLLECT on first picks, so I won nothing. It happends sometimes, but six times in a row on different games????
Got the bonus on Star Trek, won £10.70 then started to play again and got the bonus again on the next spin. The £10.70 I won on the previous bonus was removed from my account and the second bonus was exactly the same as the first. However, on the second time around I choose a different box on the 'spin till you win' feature and of couse, I knew which one was the best box to pick. So got a little more!
Spoke to support, they said technical team were around to fix bugs. I presented the evidence of the extremely low payout ratio, and nothing said.
So... at this time I do not recommend playing here as It's a bit too suspicious for my liking. I've been playing slots of 7 years online and know when things are a bit iffy!
Sorry to be a sour puss, but have closed my account and won't be returning there
