An upgrader is one spin that trades a skin you own for a chance at a dearer one. 13 of the live sites in our main Rust ranking run one, and each is scored on its upgrader first: published odds or edge, value limits, a verifier that covers the spin, and extra modes. The other 4 criteria carry the rest.
Roll Over or Roll Under, 5% to 50% chance presets
Circle Spinner or Magic Spinner, 1.5x to 10x
Pick a target, set your odds from 5% to 95%
Upgrader page states skins in for a shot at better
Win chance presets of 10, 25, 50 and 75 percent
Pick your own odds before the spin
Up to 4 skins staked, win chance 0.5% to 90%
Roll under only, with a top winstreaks board
x1.5, x2, x5, x10 or your own multiplier
$0.50 minimum, skins or balance as the stake
X2, X4 and X8 presets at 35%, 55% and 75% chance

The upgrader runs both ways: Roll Over or Roll Under, with win chance presets at 5%, 10%, 20%, 25% and 50% and a Fast Spin toggle. Each spin shows its ticket and hash, and the fairness page gives the upgrader its own tab.
2.00 free coins + 3 free cases Details
The upgrader runs as a Circle Spinner or a Magic Spinner, with multiplier buttons at 1.5x, 2x, 5x and 10x and a live upgrade chance percentage. A fairness link sits on the game and the upgrader has its own tab on the fairness page.
+3% deposit bonus Details
Stake skins or balance against a target item and set the win chance yourself, anywhere from 5% to 95%, with the chance score shown before the wheel spins. One upgrade mode, and no house edge or stake limit published.
+5% bonus on your next deposit Details
The upgrader page states the mechanic in one line: put your Rust skins in for a chance to improve them into higher value ones. No multiplier ladder, no win chance, no house edge, no stake limit and no verifier reach a logged out reader.
2 free gems + free cases + daily 5% deposit bonus
You stake up to three skins, pick a win chance from the 10, 25, 50 and 75 percent presets or add your own segment, and spin the wheel. Any spin re-derives on the fairness page from its game id.
$2.00 free + 3 free cases Details
The upgrader is listed among the modes the /provably-fair verifier covers, beside crates, crate battles, mines, the wheel and crash. The help centre has no upgrader article, so no odds table, edge or bet limit is published to a logged out reader.
1 free crate
You stake up to four skins or gems against one to four targets, which can be physical skins, gems or a mix, at a win chance between 0.5% and 90%. The checker names Upgrader and recomputes the roll, win zone and result.
0.15 gems + 3 keys
The upgrader takes one or more items, a target item and a roll under bet, and it shares the case opening seed system: client secret, hidden server secret and a nonce that steps once per roll. A top winstreaks board is public.
Upgrade a skin or balance into a pricier target at x1.5, x2, x5, x10 or a value you set, with the success probability shown before you spin. The inventory tab carries Rust items, and an Upgrade streaks mode sits next to the single upgrade.
$0.70 free balance Details
The FAQ publishes one rule for the upgrader: the minimum cost to upgrade from balance is $0.50. Skins or balance go in on the left, a target skin on the right, and the panel prints the probability before the spin.
$0.30 free balance Details
Skins or balance go in and a target item comes out, with X2, X4 and X8 presets at 35%, 55% and 75% chance. The fairness page prints the whole HMAC SHA256 roll and the commit check, but there is no seed history.
The scrap upgrader is named in the games menu. The help centre fairness article lists the wheel, coinflip, spinners, crate battles, crate jackpot, beancan blast, crate unboxing and mines, and leaves the upgrader out, so no odds, edge or bet limit is published.
$0.15 free balance Details
The upgrader has its own route in the RustNeo games menu. Its page returns nothing to a logged out reader, so the multiplier ladder, the win chance, any house edge, any stake limit and the verifier all stay unpublished.
+5% deposit bonus
Read from each site's upgrader page, FAQ and fairness page in August and September 2026, with win chance presets, value limits and any edge recorded only as published, and with no skin of ours staked.
We run no upgrader, so RustCasino is not on this page and holds no place in the order below. The sites here are scored on the criteria and weights above, from published evidence, with a reason beside every number.
Read our editorial policy and our provably fair page.
You stake a skin or an amount of balance, pick a target item worth more, and the site shows the win chance before you spin. Win and the target replaces your stake; lose and the stake is gone, and the bigger the price gap the smaller the chance. Bandit.camp runs the same idea priced in scrap, as Scrap Upgrader.
The stake is whatever the item or balance you put in is worth. BloodyCase is the only one publishing a stake floor, $0.50 per upgrade in its FAQ. RustSnowball publishes a 95% configured return and a 90% maximum displayed chance, and Rustgrade publishes X2, X4 and X8 presets at 35%, 55% and 75% chance. The rest publish no headline minimum and no maximum multiplier, and any deposit floor they do publish is in the deposits row of each block above.
Most are, and the fairness column in the table above says which. RustClash hashes a SHA256 server seed before each round across all modes, RustyLoot seeds draws from EOS block hashes, RustMagic publishes the server-seed hash but no browsable history, RustCases hashes its server secret and steps a nonce per roll, CobaltLab and RustBattle publish verifiers you can run logged out, RustSnowball publishes HMAC SHA256 test vectors anyone can run, RustNeo prints its HMAC SHA256 code on the page, Rustgrade prints the whole formula down to the 52 bit roll and the commit check, and Splits publishes a random.org seed with a committed block hash. The weakest publish no algorithm and no seed history, or hide the verifier behind a login.
The first row, and it moves whenever a score moves, because the position is the weighted total of the 5 criteria above. RustCasino runs no upgrader, so our own site is not on this list; every site that is here answers to the rubric it answers to everywhere else.
Because the heaviest criterion here is the upgrader. The hub scores how many modes a site runs; this page replaces that with the upgrader at 30%, scored on what the site publishes about it, so a site with a wide floor and a bare game page drops and a site with published odds or an edge, value limits, a verifier for the spin or extra modes climbs.
