Can it really be a coincidence that free spins on this game can be set at a value of just 0.10, and I cannot remember ever receiving any no deposit Starburst spins at a higher rate than this. The game has one of the lowest jackpots offered by any game too at just 500x your stake - I am yet to actually see a single screenshot of this jackpot being won as well. I'm sure it is not by chance too that Starburst is a super low variance game and wins above 50x bet are incredibly rare. There isn't even a bonus round to look forward to. Put all these factors together and you have a game that could have been designed specifically for the purpose of being used to give away worthless free spins.
CasinoLuck are certainly not alone in using this game for this purpose - I would hazard a guess that at least 80% of NetEnt casinos give Starburst free spins as their no deposit offer. On the plus side at least you get 25 spins for a total bonus of £2.50 at this casino - ten seems to be about the average and some casinos are even "generous" enough to give away just five 0.10 spins! The casino is also kind enough to allow you to use your winnings on any other game you please as well unlike some other sites where the free spin winnings must be used to beat the wagering requirement on Starburst alone, a frankly impossible task.
Fortunately CasinoLuck offer an excellent set of match bonuses to new players so I can forgive them for this extremely poor no deposit offering. I made a suggestion to them that they allow the free spins to be used on other games with the same betsize such as Aloha! Cluster Pays but to the best of my knowledge they have not chosen to permit that.
