Q: Why is the Steam Key of IDLE BOSS RUSH safer than the account format?

The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.

Which IDLE BOSS RUSH format should you buy?

The cheapest offer is already a key for your own account: €7.80 at Steam, so there is no reason to weigh up a shared account here.

The 2 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.
