Is Portal Sandbox free?
Yes. The single-source historical offer on the 27 Oct 2026 snapshot of the Roblox page is a price of 0, currency Robux. Joining, when the experience is public, does not require a purchase. The download page is where the client and platforms are. This page is only the price.
Optional passes, prices unknown
Twelve passes exist. Their descriptions are quoted in short form below. A direct store page still returned not found at the later review, after the experience returned to public. The pass-list response exposes descriptions and sale flags, without prices. I will not fill the gap with portalsandboxwiki's Robux column (they list figures such as 65 and 185). Those figures have no second source.

VIP is the one that changes the economy: 2x money per kill, and the author adds "NOTHING ELSE", then 2x IQ XP, a VIP chat tag, and a hide-kills option. It is not written as a damage pass. Insurance saves items for three deaths in a row. The fourth death drops them and the three saves return. Backpack Looter lets you loot a player you killed. Gun passes grant named models or appearances; their descriptions do not establish equal damage. Custom colors say they are mostly for mobile. None of this is required to play.
Do not import the Battlefield price
Battlefield 6 standard edition has a US list price of $69.99 in EA's Portal 101 article. REDSEC is described as free and includes Portal. Those are dollars on a different game. They are not a sale price for place 75108253383447. The Battlefield page keeps that split.
