How many GB is Twenty One?

0.78 GB

That is less than the typical Point-and-click game, which needs about 2 GB.

Leave at least 6 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

You wake up in a velvet-draped casino that seems suspended in a void, run by faceless dealers and watched by an unseen Host. You're told you owe a "debt of existence" and must earn your right to live another day by beating the Quota — a cash target that rises with each round. You have 5 rounds to meet or exceed the quota, or… you're out. Permanently.
