The Steam Machine is finally here, but with it comes a distinctly Valve approach to pre-orders. Sign up now for a chance at the ultimate home console, or risk missing out entirely.

Starting today, you can enter a lottery for each configuration of the Steam Machine — from 512GB to 2TB, with and without the iconic Steam Controller. Each option comes with its own set of regional shipping lists, making it a bit like trying to win a multi-region sweepstake.

Sign-ups close on June 25th, after which Valve will use randomization to determine your reservation spot. You can sign up for multiple configurations and regions, but only one reservation per household — so watch out for sneaky relatives.

Those who secure a reservation get a sweet 72-hour window to complete their purchase. But if you miss the cut, don’t fret: Valve will place you on a waitlist, with spots going to those closest to the front. It’s like a game of musical chairs for tech enthusiasts.

The good news? If you end up on the waitlist, it means more Steam Machines are coming your way eventually — even if it’s not the exact model you were hoping for. Just keep an eye on your inbox for those all-important emails from Valve.
