Judge Event Registration Infosystem (JERI)



The registration piece of JERI allows players to register for your tournament, paying online with a credit card. With JERI, you can set up multiple levels of registration, from basic admission to the tournament, to packages that include side events, additional swag, and VIP perks. You can set registration caps on levels if needed, and once those caps are reached, that level shows as sold out. This allows you to maximize your revenue, rather than charging everyone the same amount.

JERI also allows you to raise your prices as the tournament grows closer. Most organizers raise the entry fees up to 10 days before the tournament, to encourage players to register in a timely manner. We don’t call this late registration, but rather “last minute.” Not only does this provide additional revenue for you, but it encourages the players to register before that last week, to give you time to plan with confirmed registration numbers in mind.

We recommend that you upload your current player file before opening registration. When players register, JERI checks to see if they are in your player file; if they are, then the rest of their information is automatically filled in. This saves the player time, and helps guard against errors. If you have multiple player files, you can upload them and JERI will merge them into a single file that you can download.


JERI has an easy check-in process that scales to meet your tournament size. Check-in is efficient, and can be run on any smartphone or tablet. The number of staff needed for check-in is dependent upon your tournament size. Once check-in is complete, just download the TDF file to your TOM computer(s) to start the tournament. TDF files can be downloaded in a number of ways - one large TDF that includes masters, seniors, and juniors, individually by division, or with juniors and seniors combined.

Online Pairings

Online pairings are an efficient way to notify players of round pairings. After round pairing is done in TOM, the TDF file is uploaded via a web page to the online pairings site. This normally takes less than a minute, and then pairings are available online for all players. We include a link to signs you can print out that include a QR code for players to use to navigate directly to your tournament’s online pairings. Paper pairings may still needed, if there are players that do not have access to a smart phone or the internet. But we’ve found that the number of players checking the paper versions are a small percentage of the total, which definitely saves time.

Online Decklist Submission

No more paper decklists! Players can create, save, and submit decklists in our Decklist Creator. Decklist Creator works for both standard and expanded lists, and is mobile friendly. Players can print lists for tournaments not using online submission, and can also share lists to social media with our easy sharing tools.

For organizers, online decklist submission makes starting and running tournaments more efficient. Decklist submission can act as a self check-in tool for players, eliminating the need for in person check-in, while minimizing the number of no show players. Decklists can be easily retrieved and printed for your deck check team. (No more alphabetizing hundreds of lists!) The same applies if your tournament is streamed - quickly print off a copy of the list for your streamers. And since Decklist Creator enforces legality rules, no need for list checks.

Live Roster

Live roster dynamically builds as players check in or submit their decklist online. Once checked in or decklist submitted, a player can view the live roster to verify that they are in the tournament and their information is correct. This helps catch mistakes earlier, which in turn means they can be fixed sooner.

Swag Pickup

Swag pickup allows players to pick up their swag anytime during the tournament. Similar to our check-in screen, the swag pickup screen allows you to track who has picked up their swag. Players have the advantage of picking up swag when they want, and you ensure accurate distribution.

Judge Penalty System

The judge penalty system allows judges to enter and view penalties assessed during the current tournament. Judges are able to enter their own penalties as they are assessed during the tournament. Since this system is real time, other judges at the tournament can view both the penalty and the comments immediately after the penalty has been entered.

Tournament Metrics

Tournament metrics provide an "at a glance" look at registrations for your upcoming tournaments. The metrics page shows your current registrations by division, by level (if applicable), and by date.

Hive management solution

Let RK9 Labs provide the devices you need to run your tournament software, including TOM computers with scanners. Equipment will be delivered onsite, ready to go with the latest software installed. You provide a stable wireless internet connection, printers, and other non-equipment supplies (paper, toner, etc.) needed to run the tournament. This also includes hive management - oversight of all logistics of data flow in and out of the hive, including check-in, TOM initialization, match slip management, drop slips, penalty entry, and scorekeeper supervision. We are there in the hive with your staff, providing guidance, resolving problems, and helping to make things run smoothly. These options are provided for an additional fee, and require RK9 Labs to be onsite.

What's Needed?

JERI is dependent upon Stripe to collect payment. Stripe is a well known vehicle for collecting payment online via credit card. You will need to set up a Stripe account, if you don’t already have one.
