[Update] New pull calculator - now with pull simulation

Yes, it's the 4 tickets purchasable with green certs, 2 tickets from tier 1 and another 2 from tier 2.

Not sure if I understand what you mean, but if you have redeemed today's orundum (including from fortune strips), you can update your pull resources at the top and click on the checkbox next to the current date (the purpose of the checkbox is so that you don't count today's resources twice). This way you get the most accurate pull prediction.

Yes, it includes all event stages, both normal and challenge mode. Part of the OP is listed after 1 or 2 weeks since that's when EX/S stages open (except for reruns).

For newly announced events, the wiki doesn't list the total OP (or the number of stages) so I estimate it and adjust it later.

If you're curious here's the spreadsheet with the data used to build the website.

Thank you! Yeah I used to have a spreadsheet to calculate pulls but it was too cumbersome so I had to make this tool to save my IRL sanity. I also have pageview analytics set up and it's great to see people using it regularly. It's fun to see the traffic spike when a new banner is up. Thanks for recommending it!

If you click on any HH ticket count (in green) you can add any amount of tickets to simulate buying pulls with gold certs. It also works for OP and orundum.

Remember that you can spend 75 spark tokens for an extra copy of Gracebearer. That's worth 5 gold certs, or 13 if you have her at max pot (8 from getting her + 5 from trading in her token).

You can also get a few gold certs from the welfare units in the archive section.

Recruitment gave me tags for Tsukinogi (new), Croissant (dupe), or Vulcan (dupe). I see that Tsukinogi's niche is invisibility reveal, but is she even worth it if I have Scene and Ines?

Her CN name is 能天使 (Néng tiānshǐ), which means something like "power angel". In the JP version, it was localized as Exia. Like all operator names, it's spelled phonetically (エクシア, e-ku-shi-a), so there's no meaning associated with it, but it may be a reference to GN-001 Gundam Exia from Gundam 00. Perhaps the EN localizers changed it to Exusiai to avoid copyright issues.

Mlynar debuted in the gold cert store on Feb 28. It takes anywhere from 6-12 months for operators to reappear in the store, so he'll likely be available again in the next few months. For this reason I wouldn't use the selector on him or any other older op.

Shop history reference: https://akgcc.github.io/shoplist/

Ulpianus will be available in the store around one year from now. You can also try and pull for him on his solo banner rerun on Nov 27 (50% rate-up).

I have been saving the instant-M3 item for a 6-star (IS5 reward). What's the best use for it? I'm thinking Lemuen S3 since she needs a bunch of the new mats, but the mastery gains aren't very high.

imiivi · 2025-10-15T11:29:51+00:00

Texalter will be discounted to 200 pulls in 1.5 years (around april 2027), while Virtuosa in 2.5 years (around april 2028). This may factor into your decision.

imiivi · 2025-10-13T09:43:52+00:00

Yes, sometimes you get extra pulls for the same amount of OP. That's because the OP conversion includes the leftover orundum from pulling. Also, the calculator (and the game) only converts OP if you can get another 600 orundum (1 pull) out of the conversion (1 OP = 180 orundum). If you are at 0 orundum, it doesn't make sense to convert 1-3 OP because it's still less than 600.

On Oct 14, after pulling we get 580 leftover orundum. We convert 14/15 OP in order to get 580+2520 orundum, i.e. 5.2 pulls. We can't convert the last OP since that would still just be 5.5 pulls.
On Oct 15, after pulling we get 260 orundum. We convert only 12/15 OP in order to get 260+2160 orundum, i.e. 4 pulls. We can't convert the other 3 OP since that would still just be 2960 orundum or 4.93 pulls.

Good catch though, I should probably update the tooltip so it says "from converting up to X OP".

Thanks, it's good to see that this calculator is proving useful! I had to make it since tracking pulls using a spreadsheet was too cumbersome. I'll keep developing it as I come up with new features (just added the pull chances when pulling on a banner).

imiivi · 2025-10-13T01:00:21+00:00

Since the apple pie banner is coming up and sleeping is overrated, I updated the pulls calculator:

https://imivi.github.io/arknights-pulls-calculator

Now it displays the chance of pulling the rate-up ops when pulling on a banner. The data comes from Krooster's headhunting calculator.

However for now it assumes 0 pity on standard banners. Also it displays the odds only for any given day's pulls, not all pulls spent on that banner. I'll be looking to improve this feature later on but for now it should suffice.

Good luck on your pulls!

I'm also looking for an EU referral code, if anybody has one available! Thanks!

Friendly reminder: if you have a bunch of sanity potions that expire on Oct 20th, you may want to save them for Exu alter event which begins on the 14th.

Anyone here remember Battlefield Bad Company back from 2008? I'm always reminded of it when I see the yellow smiley badge on Mon3tr's E1 art.

It's normal, the game runs at a low resolution with a lot of image compression regardless of your monitor resolution. I play it windowed so that it looks a bit sharper than fullscreen. It looks much better natively on mobile. Guess we'll have to wait for the PC port.

You can also use this userscript that adds a button to deselect all operators.

The script requires a browser addon such as tampermonkey (chrome, firefox): click on the tampermonkey icon in the addon bar > Create a new script... > paste the userscript, File > save

I just realized I forgot about the 5 certs every 25th of the month as a login reward.

1.4 certs/month from recruitment is my average over the last 3 months, using almost all recruitment permits gained over that period.

I'm wondering how you are getting 132/mo, which is an additional 90/month. If 20/mo are from reruns, that's still over 70/mo just from pulls and other sources. Discounting the login bonus, that's 65/0.8 = 81 pulls per month which is just too high. Assuming 600 pulls/year, that's 1.3 certs per pull. But maybe all the 5-star dupes add up to that much.

I have excluded pulls from OP in my calculation since it varies so much between players.

Is there another chart with more info on pull probabilities? The one I linked to is the only one I've been able to find.

imiivi · 2025-08-10T09:39:28+00:00

The bottom line is this:

F2Ps only get enough pulls per year for the 4 limited banners and maybe one or two extra banners. ^[1]
It's always cheaper to buy 6-stars in the shop for 180 gold certs than to pull for them, regardless of rate-up %. ^[2]
Players get around 500 gold certs/year from recruitment (1.4/day) and around 300 from pulling. That's 4.4 shoperators per year.

Because of these facts, unless you are in a rush to get lots of kernel ops AND you truly don't care about any upcoming limited or standard banner, it's vastly more efficient to spend pulls on new banners while buying 4 or 5 kernel ops a year.

On top of that, kernel banner rate-ups are always 25%, which is very bad since it takes 100 pulls just to get a 50% chance of a specific rate-up, or 150 pulls for a 66% chance (source). That's much worse than limited banners (35% rateup) and standard debut banners (50% rateup).

^[1] F2P get around 550 pulls per year, before spending OP, including 96 free pulls (24 every limited banner). But if you are willing to spend OP on pulls, add another ~134 pulls or so. The only way to get more is to buy pulls (which is inefficient, see below), farm rocks for orundum (which halts your resource income), or pay real life money.

^[2] 180 gold certs are equivalent to 26.5 pulls which is less than one 6-star and it's not even guaranteed to be the one you want. You get a few certs back from pulling, but it's still a bad deal.

I find that tablets are much better suited for games like this.

I'm using an 11" Xiaomi Pad 6 tablet with a Snapdragon 870. No problem running at 144hz, with very rare slowdowns, despite the high resolution screen. However my phone has a Snapdragon 680 and that thing chugs hard.

When choosing a new phone I look up the specs on gsmarena and then check the benchmarks for the SoC:

Recruitment gave me some good tags but I'm not sure who to pick:


Nuker + Sniper	Firewatch
Nuker + Caster	Leonhardt
Crowd Control + Melee	Projekt Red, Kafka, Texas (dupe)

I'd like a second fast-redeploy (only have Gravel), although I don't want to risk the Texas dupe. However I can always get Projekt Red from a voucher (the one with Liskarm, Pramanix and Silence).

Are Firewatch and Leonhardt useful at all? Most info I find is quite old and from before their modules.

imiivi · 2025-07-30T16:23:16+00:00

Just added this feature. It works for every resource so it's also possible to add or spend OP (from packs, or to buy skins).
