How To Play
Win by reaching
1 TW
of active compute before 2036.
Compute needs a
pod
with GPUs and radiators installed. Diagonal connections count.
Pod
= radiation-hardened housing for GPUs and supporting equipment.
Newly built modules orbit Earth/Moon. Click one, then click a grid tile to place it.
Install GPUs and radiators by selecting them and clicking a hard pod.
Heat stress shortens lifespan. Heat % is shown on each compute module.
Solar power beams to all compute modules automatically.
