Venue Requirements
In-Person Events
You need power outlets for everyone, WiFi that handles concurrent users, projection for instructions (recommended), and tables with computer space.
For network, plan 3 Mbps per participant or more. Standard HTTPS (port 443) must be open. The network can't block kc7cyber.com. A guest network helps if your main network is restricted.
Virtual Events
Hosts need a video platform (Zoom, Teams, Discord), screen sharing, 10 Mbps upload or more, and a backup communication channel.
Participants need access to the video platform, the ability to view a shared screen, and ideally a phone for video alongside a computer for the game.
Test Before the Event
One week before. Test the participant link on multiple browsers, verify network capacity, check firewall and content filter settings, and test projection or screen sharing.
Day before. Confirm all links work, run through with a sample participant account, verify venue WiFi credentials, and have backup access methods ready.
Day of. Arrive early, fully test one machine, and keep IT support contact info handy.
Common Blockers
School and Corporate Networks
Firewall blocking KC7? Whitelist *.kc7cyber.com, switch to the guest network, or fall back to mobile hotspots.
Content filter blocking the game? Request a temporary exception, work with IT to pre-approve, and test the week before.
Browser Issues
Old browser version? Update before the event or have an alternate browser ready.
Extensions interfering? Switch to incognito mode, disable ad blockers temporarily, or change browsers.
Device Notes
Chromebook
Yes
Keep Chrome OS updated. Check school management settings.
iPad or tablet
Functional
Smaller screens and touch slow people down. An external keyboard helps.
Phone
Not recommended
Use only for event communication, not play.

Test KC7 access from school or corporate networks well in advance. Some networks block cloud services or require IT approval for whitelisting.
Tips for Large Events
For 50 or more participants, stagger start times, line up dedicated IT support, test at maximum expected load, and have offline activities ready as a backup.
Quick Troubleshooting
Can't access KC7. Check internet, try a different browser, clear cache, disable VPN, check firewall.
Slow performance. Close unnecessary tabs, check internet speed, try a wired connection, lower video quality on virtual events.
Support
For technical issues during an event, start with this checklist, then visit Discord for real-time help, or email events@kc7cyber.com for a 24-48 hour response.
