How a flip is matched
One player creates a flip by putting skins or balance into it and picking a side. The flip then sits in the lobby until a second player joins with a similar value. Sites set a range for how close the two sides must be, for example within a few percent either way, so nobody can join a 50-coin flip with a 5-coin skin.
Once both sides are in, a provably fair roll decides the winner, and the winner receives both sides' items minus the site's fee. If nobody joins, most sites let you cancel and get your items back, and many offer a bot that will take the other side straight away.
There are two ways sites handle the odds, and it is worth knowing which one you are on:
- Flat 50/50. Each side has exactly half the chance, whatever small difference in value the matching range allowed.
- Weighted by value. Your chance equals your share of the total. Put in 48 coins against 52 and you hold 48% of the roll.
Our coinflip and jackpot guide goes further into both systems and how the fee changes the maths.
Where the fee sits
The fee is the house edge in coinflip, and it is easy to forget because the roll itself looks perfectly fair. Say you and an opponent each put in 10 coins and the site takes an example fee of 5% from the 20-coin pot. The winner receives 19 coins. Over many flips you win about half the time, so you get back about 9.50 coins for every 10 you stake.
Some sites take the fee as items from the pot rather than as coins, so the winner receives slightly fewer skins than were played. Either way, check the fee on the site's FAQ or fairness page and compare it across sites. On a game this simple, the fee is most of what separates one coinflip from another.
What a good coinflip page shows
- The fee, stated as a percentage.
- The matching range for joining a flip.
- Every item on both sides with its value, before you commit.
- A history of finished flips that you can open and verify. Our provably fair guide explains the check.
- The option to flip with balance, so you are not forced to find a skin that matches someone else's value.
Creating a flip or joining one
Creating a flip lets you choose the stake and wait. Joining one lets you see exactly what sits on the other side before you commit. The odds are the same either way, so the choice comes down to control.
When you join, check that the items on the other side are valued in line with market prices, and whether the site weights odds by value. On a weighted site, joining slightly under the creator's value costs you a little chance. When you create, pick a stake you would be fine losing in one roll, because one roll is all it takes.
The four sites we would flip on
RustEasy. First overall and the only site here that takes CS2 skins as well as Rust skins, so you can fund flips from either inventory. Trust and payout scores of 9.3 and 9.4 are the highest in this table. CSGOCORN adds a 5% deposit bonus.
RustyLoot. Third overall, founded 2022, with coinflip and jackpot side by side. NEWCORN gives $2.00 free on signup, enough for a few low flips before you deposit anything.
Howl.gg. Howl.gg skips cases and battles entirely. Its line-up is wheel, slots, jackpot, coinflip, dice, blackjack and live casino, which makes it the pick here for players who mostly flip. It has run since 2017 and is the only site in our data that also pays out by bank transfer. Its CSGOCORN offer is a 25% instant rakeback boost, which suits a high-volume game like coinflip better than a one-off free balance would.
RustBattle. Founded 2024 and fifth overall. Coinflip sits in its lobby next to Battles, Crash and Upgrader. CORN gives $2.00 plus three free cases.
Bandit.Camp, RustMagic, RustyPot and RustChance also run coinflip. RustyPot is the specialist of the group, with only jackpot and coinflip, but it has no crypto withdrawals and no live chat. RustChance sits last in our ranking. Codes for all eight are on the bonus codes page.
Where coinflip players lose more than the fee
Item pricing. The value a site puts on a skin can differ from what it sells for on the Steam Community Market. If you flip skins the site values low, you are giving up value before the roll.
Flipping the whole inventory. One flip with everything you own is a coin toss for your inventory, minus a fee. Splitting a balance into smaller flips does not change the edge, but it does give you a point at which to stop.
Flipping to win something back. The coin has no memory of your last loss. Raising the stake to recover is the fastest way to turn a bad night into a worse one.
Flips arranged outside a site. A "coinflip" set up in Discord DMs or through a self-appointed middleman has no fairness system behind it. It is a common scam pattern, covered in our guide to Steam trade scams.
