Hello,
Unfortunately we do not have any information on event prior to their release. You will have to stay tuned to the weekly event announcements.
Thank you and have a great day!

Sorry but that is the reality of being a pleb, i mean sorry a F2P in the game. You gotta be active, check-in straight a month for 250 coupons. While the current server i'm in (2004) a player who invested 2k dollars in a week, got 5k coupons (god knows how many times i couldn't count) on a single click, long story short that fellow just secured the next fuku with click on shinobi feast coming from recharge, a f2p to secure a fuku needs to spend around 3 months nearly. Gap between F2P/P2W is beyond astronomical. And they hardly increased any prize. The only increase i can remember at once is Myoboku Trial's final prize (coupon on hit) was 20 to 40. And even that is hardly visible.

Most likely it will be every year in September because it's a kind of going back to school, but it's impossible to predict all events in advance

1st player spent 2000$

2nd player spent 0$

Let it sink again first person spent 2000$ real money and other one didn't spend anything. What do you f2p people expect outside of like you said "beyond astronomical gap"? You expect this kind of whaling to have close to no effect on power/ninjas? Not trolling for real I wonder what is the thought process here because I don't get it.

As for events / coupons in 2022 I said it 100times before, ask Tachibana, I argue with her a lot of the time so you can't tell that Im Oasis fanboy but here you guys are in denial not Oasis. Amount of free things we have right now in comparison to early versions of this game is literally night and day. (in a positive way ofc)

Not to mention that (I could be wrong here) collosseum gamemode from China has similar rewards to infinite illusion so once that thing is added we will get even more freebies.

Well, of course, day and night, it is especially remarkable that the fragments of the flags were removed and secret scroll plate frag ...... sarcasm, if anything.

Simple event cycle life. Something is nerfed, something is buffed nothing special. You guys are always writing those rants completly from your own view. You are pissed off because YOU need fragments of flags/plates but to people like me that don't need any of them its finally after months or years even a positive change.

Not to mention that you guys are in this tunnel vision mentality about lucky stars being god event when there are other options some even better from time to time. You can get your flags from multiple events. For example if there is a ninja you want in lucky sn4tch + fuku deals week combo spent there get on top op everything few command flags and you are good to go

I was just giving an example, i dont really intend to make list of spending of people in the server i'm playing here (so many went for the maxed lucky * and 3-4 people got Rin Sw pack not to mention) Fellow who opened the topic asked about an improvement in f2p prizes by setting monthly rewards as an example. And i wanted to say an increase in rewards is unlikely to happen because throughout the years, only thing they boosted in f2p prizes is myoboku trial's coupon amount. Oh yeah and they added up Infinite Illusion, guess who is making it to top 10 in the lists? Yeah you will be surprised.

Part about illusion obviously true but let's be real. F2p community will never be able to compete with spenders (well there are some extreme cases...) and that's just how it is in those kind of games... As for no improvements:

1) Firework Festival

2) Myoboku trial -> + change to double the coupons

3) Infinite illusion

4) Lanterns event

5) Seasonal rewards

6) 1time events like halloween or now this back-to-school thing (obviously it will be 1time per year)

7) That cat / beans whatever it's called event

Now remove everything above on top of free power items from sun/moon coins and that's how people played this game for first few years and there was less ranting about events than now. Extra 40 coupons daily won't improve this game at all. Server merges, changes to activities rewards and things outside of Oasis power will like dropping big update that completes story, has Kaguya, 8th gate guy in it and clearly shows that game is not dying but instead moves into Borutoverse. That would be something to be hyped about not debating for 5 pages like I sometimes see in weekly event pages that fireworks have meh ninja or that fukuromaru deals is bad. If it is then unlucky next one will be better... (and mostly in this case better = will have ninja that person X wants but person Y doesnt and that one will start their own rant)

PS Many of my f2p friends quit the game but none of them told me the reason is events are bad or I have too few coupons. Let's imagine that I can transfer 50k coupons to my friend and he will still not come back cuz that's not the reason why people quit.

To not be completly offtopic here I would say tho that those 1 time events are really good idea so don't forget them in the future. Im pretty sure we skipped last years halloween event for some reason.

Last ucky * i spend 15000 coupon, i F2P, and no one flag not drop!!!

The devs are in charge of event scheduling and release. Unfortunately, as mentioned, the general release schedule of events is not given out until the official announcement a night or two before the new event week.
