Keep the packets
flowing._
An endless network-building survival game. Design a topology, keep packets flowing to the cloud, and hold off rising traffic and equipment failure for as long as you can. No account, no server — your run and personal best live in your browser.
Build the topology
Drop in switches, routers, wireless access points, firewalls, and servers, then wire them by hand. Only a router can reach the Cloud Edge — everything else is up to you.
Route under pressure
Every forwarding device serves realtime traffic first, then streaming, then bulk. Packets that don't fit queue for up to 6 ticks before they're lost for good — watch the load, not just the color.
Upgrade on a budget
Run cable tiers from Copper up to 100 Gigabit, or bulk-apply Site Upgrades for 15% off. Change your mind and salvage 90% of what you spent back.
THE CORE TENSION
Four states.
One job: stay ahead of demand.
Every cable shows its tier and a live load/capacity readout in real time. Read the board, find the choke point, and upgrade or reroute before congestion turns into a dropped packet — or, in the harder scenarios, a failed link.
Cable is up, nothing crossing it this tick. Ready the moment a route needs it.
Traffic is under capacity and moving clean. This is where combo and score add up.
Load exceeds capacity. Overflow packets queue for up to 6 ticks, then drop — and 3+ drops in one tick resets your combo instantly.
In equipment-failure scenarios, an overloaded link or device can go down outright. It takes 4 ticks to recover while you route around it.
Five traffic types. Five ways to build around them.
Source devices generate packets every tick; infrastructure decides whether those packets have anywhere to go. Realtime traffic always gets served first — bulk traffic waits.
PC
1 wired port, Wi-Fi as a backup. Steady, predictable load — served last when a link is tight.
TV
Generates 2 packets/tick — double a PC's rate. Wired, with Wi-Fi as a second route.
Console
Wired plus Wi-Fi backup. Realtime priority means it keeps flowing even when PCs are queuing.
Phone
No wired port — it only connects inside an access point's coverage circle. Realtime priority.
Tablet
Also Wi-Fi only, streaming priority, generating 2 packets/tick — a heavier wireless client.
Switch
$80, 8 pkt/tick base throughput. The workhorse that fans a router out to every device.
Router
$140, 8 ports, 20 pkt/tick. The only device that may connect to the Cloud Edge — every path ends here.
Wireless AP
$90. Range and throughput scale with Wi-Fi generation, from 802.11b up through Wi-Fi 7 — one uplink port back to your wired network.
Firewall
$110, 12 pkt/tick. Can block one device kind outright — useful for isolating traffic between subnets.
Server
$120, unlimited throughput. A cross-subnet destination — about 30% of traffic targets a server instead of the cloud.
