Epic Games Store users have until October 8 to claim Bridge Constructor Studio completely free on mobile devices. The 2025 simulation game is available through the Epic Games Store applications for iOS and Android, giving players a new addition to their mobile libraries without an upfront cost.

Bridge Constructor Studio challenges players to design and build bridges that can safely support vehicles as they travel across difficult environments. Its physics-based puzzles require careful planning, with players balancing construction costs, materials, weight, and stability. The game comes from ClockStone, the developer behind the Bridge Constructor series. The studio has also created crossover entries featuring popular properties such as Portal and The Walking Dead. Bridge Constructor: The Walking Dead was previously offered as an Epic Games Store freebie in 2021 and again in 2025.

Players can claim Bridge Constructor Studio through the iOS version of the Epic Games Store or the Android application. Once claimed, the game is added to the user’s library, although availability and access may depend on the relevant mobile platform and Epic Games Store app. The promotion is part of Epic’s wider free-game program, which has offered more than 500 games since it began in 2018. October’s other giveaways have included Buried Stars and System Shock 2: 25th Anniversary Remaster.

On October 8, Bridge Constructor Studio will leave the promotion. Epic is scheduled to replace the offer with Out of Sight and TerraScape, giving users a new pair of free games to claim.
