However, I noticed that the offer has been updated since then and you now receive 50 spins on a much better game, Aloha! Cluster Pays, which I think makes it worthy of a mention all of it's own.
The match bonus itself is what really lets this bonus down though - it's just 50% up to a maximum bonus amount of £100 so you'll need to deposit £200 to take full advantage. I wouldn't do that though as the wagering requirement is very harsh at 35x the deposit plus bonus amount, meaning eve if you go for the minimum required deposit of £20 you'll still end up with £1050 of wagering to complete before you are eligible for a withdrawal. That's certainly not something I would recommend in order to receive £5 worth of free spins, but if your looking for a little more playtime on your session with the added possibility of a "second chance" via 50 free spins on a reasonably decent slot then maybe this is a bonus worth taking? Chances are though you can find a new casino to join with a better first deposit bonus if you really try hard enough!
