Steam is further expanding its free catalog. On February 23, 2026, the platform saw the arrival of Synergism, an idle game already cult on other media, now available free of charge for all users. Rated 97% positive reviews, it promises hundreds, even thousands of hours of play.
If you’re looking for a new obsession without spending a dime, Synergism might just be the ticket. Actively developed since 2019 and publicly launched in 2020, the title continues to be updated and today has new visibility on Steam.
Synergism lands for free on Steam with 97% positive reviews
Steam regularly offers free games, but few arrive with a solidly established reputation. Synergism falls into this category. Already known to fans of incremental games, it can now be downloaded and stored for free in the Steam library. Its current score of 97% positive reviews immediately reinforces its credibility among curious people. Some experienced players of the genre do not hesitate to place it at the top of their rankings. One described it as “one of the best idle games of all time, if not the best.”
A massive idle game with hundreds of improvements
Synergism belongs to the family of idle or incremental games. The principle is simple in appearance: accumulate resources, unlock improvements, reset to progress faster, then start again with ever more powerful multipliers.
But here the scale changes. The game features hundreds of upgrades, numerous prestige levels, and progression that can span thousands of hours.
Developers Platonic and Khafra themselves sum up the experience like this: “Synergism is a content-rich idle incremental game… with numerous prestige levels, hundreds of achievements, cute little pixel art icons and much more! Your Synergism adventure begins with just 100 coins. Hire your first worker, and the rest is history. This little worker will remain indispensable even in the late game, and the end-game features will allow him to gain in power. Synergy!
Steam players seduced from the first hours
Since its arrival on Steam, the idle community has quickly mobilized. The first feedback confirms the enthusiasm observed on other platforms. One player explains: “As a serious fan of incremental games, this one meets my expectations perfectly.” Another is content with a direct opinion: “loved this game”. This success can also be explained by the depth of the content. Unlike some idle games which plateau after a few days, Synergism multiplies the layers of progression, which pushes players to constantly optimize their strategy.
Active development since 2019
Synergism is not an improvised project. In active development since 2019, launched publicly in 2020, it still benefits from regular updates today.
Its arrival on Steam represents a new important step. The platform offers massive visibility and attracts varied profiles, from curious casual players to enthusiasts of the incremental genre.
Free, rich in content and already praised by its community, Synergism stands out as one of the strongest proposals of the moment in the category of idle games on Steam.
