Too many dropped requests.
Reached wave 1
Requests spawn top-left and must reach the client bottom-right before your queue overflows.
Pick a tool below, then tap a tile to build. Tap a placed belt / server / cache / balancer again to rotate its output direction.
Belt — free, just routes traffic.
Balancer — splits traffic round-robin across two directions.
Server — processes a request, but only holds one at a time.
Cache — tags requests so the next server handles them almost instantly.
Bulldoze — removes a tile, partial refund.
Compute regenerates over time and is spent on servers, caches and balancers. Traffic ramps up every wave — keep throughput ahead of demand.
