The wagering for this bonus is only 4x if you choose to play only bingo. I'm sure most people will be more interested in the slots, which have a contribution percentage of 10% giving a 40x wagering requirement. If table games are your thing you'll need to double ro quadruple that figure again, but blackjack, baccarat and video poker along with a handful of other table games are excluded completely so I'm not sure which table games are allowed!
Another oddity in the way Jackpot Joy choose to promote this bonus, they state it is a 250% match up to £100 but in actual fact they mean you can deposit up to £100 for the maximum bonus - so you can actually receive £250 at the most! It's all very confusing and this page should probably be updated to make these facts a little more clear.
Other than these though the promotional terms and this casino are much simpler than I've become used to over the past couple of years, which can only be a good thing although it is perhaps a result of the rather limited game selection.
I only deposited £10 when I took this bonus so played with £35 but it didn't last long - I don't remember them having any NetEnt or WMS games back then and I wasted most of my balance on Rainbow Riches without seeing anything over 20x my stake in return, so I never managed a withdrawal and didn't really have a great deal of fun either. That's not the bonuses fault though!
