It's RNG based

It's random but when there was the 40cp prize, the likelihood of you getting the big prize was VERY high. But it's a risk you have to be willing to take.

Oh I see, thanks for informing me. I will still try my luck whenever I make 10k coupons. The kid character called indra looks cool.

I've spent by my estimation somewhere between 150 and 200k coupons on lucky stars and never got a jackpot. And it's not like I have bad luck, most players don't win the jackpot either, the winners are a lucky few.

You'd be better off saving up your coupons to the 30-35k range to complete a full fuku rebate. Lucky star wheel is still one of the best events to spend on for the majority of the players, so you can do that too, and who knows, you might get lucky. Just don't expect it.

Do all events with jackpots for the other stuff that you get - not the jackpot itself.

150-200k coupons wow, I'm in lost for words. If the event is based on that much luck, I shall save my coupons to 30k-ish and do full fuku. At least it gives really nice ninja/s and prizes. Thanks for the heads up though.

Life of a f2p player is hard :)

The event is totally RGN and if your lucky, you can even get it in 1st spin...
