20k would take about 20 weeks if you max out convoy/plunder and the group wheel. As well as staying on 1 hour for the 10 coupons. As for what ninja will appear? Probably something that would be a good position 2 support or a previously god tier ninja that has been a bit power crept. Its mainly on the other events that appear. For instance, last time there was Six Paths Naruto in lucky stars with Fuku deals being the new Gamariki summon and Konan Taisho. When I did fuku deals, it was Konan Angel of God in Lucky Stars with Edo Roshi in Fuku deals.

90 a day from 2 ss convoy.

10 from daily time login

Those alone is 100 daily so 200 days

But if you add in other random coupon stuff like lucky wheel and picking right ninja for quiz and the 180 of doing 2 group summons a week you can get it much sooner but with just guaranteed coupons about 22 weeks

yeesh hella f2p mode, but good luck

I'd say around 4 months.

Rough est.

910 a week convoy x 4 = 3640 a month

200 Monthly login

3840 cps a month est. x 5 = 19200

It can be more when you do events like Myoboku. weekend missions etc.

It's 4000-4200 per month,with coupons from tree,sign in,convoy and plunder,group summon,Myoboku event.Not including group wheel,there is not fixed number.Think is possible in 4 months to get 20k.

it took me 3 months total to save up 20k (but i'm not really f2p). if i just take the f2p parts into consideration, i make slightly over 1k in a week. i made a detailed spreadsheet to help me track expenses when i was saving for 20k. my main sources of coupons:

- convoy/plunder

- group wheel (i defaulted this at 10 coupons a day to make room for rng)

- group summon

- friendship tree

- daily 1hr login

- myoboku trial/wishing lantern

- ninja puzzle

- monthly login

Realistically speaking it will take about 5 months, since you won't remember to do convoy every day and things happen, however If you do well in Zenith you could speed it up by quite a bit

convoy doesnt take much effort. get yourself a daily checklist so you don't miss out on important things like this. even in the midst of my exams i managed to take a 5 minute break to complete convoys and plunder.

i imagine if you're determined to save up 20k coupons, you're determined enough not to forget convoy.

btw i checked my spreadsheet, you can reliably get 1.2k coupons a week if you complete the list of tasks i gave in my previous post. granted you'll miss out on cave keys from the wishing tree, but if you're doing 3v3 and dailies regularly, you should still be able to hit 1k50 keys a month as i did.

Around 3 to 4 months

If you buy the monthly card, both the 300 & 600, it takes less than 2 months. But it will cost you around 35$.

Just some specifications:

1) Ninja puzzle is not there every week.

2) if you are f2p, theoretically, unless you are in a dead server, you can be plundered and you may fail in plundering. That means you are granted to get only 50 coupons per day, even if you can eventually get up to 130.

3) getting 19 or 21 coupons instead of 4 cave keys from the wishing tree is very counterproductive. They are 120 free keys per month you are not getting for free (so 24000 moon scrolls you do not spend on myoboku gifts, bells, unbound rune packets, etc...).

i got 20k in 4 months and 10 days (i am f2p)

1. ninja puzzle comes and goes, but we're talking about on average. that means it doesnt need to be there every week. from personal experience, it comes about once every 2 weeks. I put this down in my spreadsheet just for logistic purposes since it is still a source of coupons. it still adds to the overall total of the coupons and is a necessary component.

2. lol then you just gotta deal with it and adjust accordingly

3. even by claiming coupons from the wishing tree, you should still be able to reach 1050 keys per month (as i have already mentioned in a previous post). I'm speaking, repeatedly, from personal experience. Even if you level freeze. Yes, it is a loss of value. No, it will not affect you drastically. No, you don't have to keep claiming coupons from the wishing tree after you've achieved 20k coupons. This is the way i managed to ac*ulate 20k as fast as possible.

if you wanted dither and quibble about small amounts of value loss you wouldnt bother rushing to save 20k anyway.

you lose huge amounts of both power and value when you're going for huge goals like this, and as time goes on, the power loss is a much larger concern that the loss of value. you can fall behind by as much as 15-20k bp during the time you're saving up and it's more important to minimizes this than value loss

it took me 3 months (I got naruto 6p and gamriki)

my friend said he saved up 20k in 2 months

Usually when people ask how to save up coupons, it is meant for f2p and without use of any ingots to get coupons. That being said 20k in 2 months is impossible for a f2p.
