March 18, 2019: Get Ready For The Kingdom Cup!

The Tempest Cup is raging in thousands of cities around the world, but in the eye of the storm, we'll take the opportunity to announce what's on the horizon! It's time to start strategizing for the Arena's next Cup: the Kingdom Cup!
Prepare to show the world your mastery with your battle team of Fire, Ice, Dragon, and Steel-type Pokemon! This Cup repeats the 'one per species' rule introduced in February, but the competition will be fierce and novel. Be sure to study hard, build your best team, and we'll see you in the Arena in April. Read more here.
We're also excited to share that the Kingdom Cup is the first Arena Cup with official Cup prize items! Take a look:
From now on, Community Leaders have the option to order these official items from the Arena to sell or award at their accredited Cup tournaments! We love how the first run turned out, and can't wait to begin collecting all the Series 1 collectibles. (Boulder, Twilight, and Tempest Cup items will become available retroactively - but we're nailing down our international supply chain first.) Pre-orders for the Arena's May Cup will open tomorrow!
Leaderboards, Player Tiers, & global Rank
Leaderboards, Player Tiers, and global Player Rank have taken the Arena team much more energy and resources than we anticipated to finalize, but we've taken time to make sure they'll be meaningful and motivating to everyone who participates in the Arena. We've have needed to resolve a lot of complexity in policy, logistics, and development - but we're very happy with where it's landing, and we hope you will be too. Stay tuned for announcements on that front soon!
Find a Local Tournament!
Our Tournament Map which launched last month lists over 1,500+ tournaments taking place in the last two weeks of March! Never fought in the Arena before? Find a chance to compete locally on the map!
Good luck to all in the last two weeks of the Tempest Cup! Keep the feedback coming! And we'll see you in the Arena.
February 15, 2019: Announcing The Tempest Cup!

The Twilight Cup has 1,500+ tournaments scheduled for the next two weekends, but we're now two weeks from March! That means it's time to start strategizing for the Arena's next Cup: the Tempest Cup!
Get ready to prove yourself and increase your player rank with your battle team of Electric, Ice, Flying, and Ground-type Pokemon! This Cup repeats the 'one per species' rule introduced in February, but brings an entirely new meta - so get ready to do your research, assemble your team, and we'll see you in the Arena in March. Read more here.
Take note: several competitive species are re-usable this Cup from the previous two - so look for opportunities to save Stardust and Candy!

Also, be sure to check out our brand new Tournament Map, which lists over 1,500+ tournaments taking place in the last two weeks of February! Then stay tuned for more info about leaderboards (nearly complete!), collectible mementos on your Travelers Card, and player tiers next week.
Good luck to everyone competing in their Twilight Cup soon! Keep the feedback coming! We'll see you in the Arena.
February 1, 2019: The Boulder Cup Report!

January's Boulder Cup concluded at midnight last night - so it's time for the Cup Report! Overall, our inaugural Cup was a massive, global success. Without further ado, here's how the Arena weighed-in in January:
Boulder Cup Cumulative Stats:
- 1,935 Total Completed Cups
- 20,797 Total Participants
- 1,570 Total Host Communities
What an amazing turnout! Over 20,000 unique participants brought their best Rock, Ground, Steel, and Fighting-type teams to compete in the Arena at over 1,500 communities around the world! Thanks to all the amazing League community leaders who donated time (and prizes) in order to put on awesome tournament experiences in cities around the world.
Now February is here, it's time to get ready for the Arena's next challenge: the Twilight Cup!
Also, two quick frequently asked questions we'd like to answer while we're here:
Two Cup FAQs:
- 1: Are Alolan Muk & Kanto Muk Acceptable on the Same Team?
With the Twilight Cup's "one-per-species" rule, the Arena will permit multiple Pokemon 'forms' of the same species as long as they have different typing. (So, Spinda forms = not permitted. Alolans = permitted.)- 2: What happens if new species or combat changes launch in-game during a Cup?
Because Arena Cups last a full month on average, there will often be new species and even combat changes during a Cup. As a general rule, all new species are permitted unless explicitly banned. The Arena reserves the right to ban new species (or even existing species after combat changes) if the diversity or balance of the Cup would be sufficiently compromised to warrant it. This will, however, be a hopefully rare occurrence!
Now stay tuned for news on leaderboards and more soon!
January 25, 2019: Announcing The Twilight Cup!

January's Boulder Cup has only one week remaining - so it's high time we looked forward to February's Arena Cup: the Twilight Cup!
Get ready to face a whole new challenge with your best-designed team of Dark, Fairy, Poison, and Ghost-type Pokemon! This Cup comes with a few new rules and an entirely new meta - so get ready to do your research, assemble your team, and we'll see you in the Arena in February. Read more here. (Note: The competitive season's monthly Cups will not simply follow Kanto gym themes every month, but are instead designed each month to take advantage of some of the most interesting and well-balanced challenges available!)
While we're excited to share a full Cup Report after the Boulder Cup concludes, the Arena team has been watching closely and listening to all the awesome feedback shared in the League Discord server, on the Arena subreddit, and in our own communities all month!
The January Cup was the first of its kind - and overall has been a major success. With that, however, a few things have clearly needed more clarity. So with the February Cup comes the following NEW rule modifications for ALL ranked play:
Ranked Play Rule Changes & Clarifications:
General Arena Rules (Effective Immediately):
- Invite Priority Coin Toss: An optional coin toss can be requested to determine who invites/receives each battle invite. This addresses growing evidence (shoutout to DownWithTTP for the thorough examination!) that simultaneously fired special moves ("charge moves") are tie-broken non-randomly. See Rule #4 in the abbreviated Arena Rules for more info.
- Re-matches due to technical issues have had procedures clarified! Namely, that players are to begin re-matches with the same exact line-up as the bugged game, and what to do in additional 'corner cases.'
As for the Twilight Cup - we are adding an additional Cup rule this month as well: only one of each species may be used on your team of 6!
Along with these updates and our new Arena Cup, we're also rolling out a group of updates to make things even smoother and faster for both admins and competitors:
v1.5.0 Patch Notes:
Usability / QoL Improvements:
- Major Navigation Improvements: It's now far easier to get where you need to go from nearly every page
- Cancel/Conclude Tournament Safeguards: No more prematurely concluding or canceling tournaments accidentally
- Edit Battle Team After Check-In: Simpler way to edit your battle team right up til the tournament begins
- Clearer Check-In Code Info: Check-in codes are there so you don't have to take roll in person. No need to open check-ins til right before the tourney starts!
Bug Fixes:
- iOS Fix: Admin & staff match corrections now work from iOS devices
- Buchholz Adding Rematches: Buchholz tie-breakers no longer overlook facing an opponent 2x
- Duplicate Check-in Fix: Participants no longer need to enter a check-in code twice
So what's next on deck? The roadmap features we listed in our last update (Jan 12) are nearly all complete! Look forward to an update with some brand new toys soon.
Good luck to everyone competing in their Boulder Cup this week! Keep the feedback coming! We'll see you in the Arena.

We'll have more updates soon. Keep the feedback coming! Best of luck in your own Cup battles!
