Inviting beaches and delightful physics await you in literal sandbox game, Sandcastle

Developer Bubblebird Studio and publisher Future Friends Games have revealed Sandcastle, a physics-based simulation game that turns beachside crafting into a literal digital sandbox. Built as a relaxing, cozy experience free of time limits and competitive pressure, the title focuses on building sand structures while dealing with realistic coastal elements.

At the center of Sandcastle is a dedicated water and sand physics system. The game's simulated environment models realistic sand properties, causing sand to compact, crumble, or retain its shape depending on moisture levels and applied pressure. At the same time, ocean waves flow, pool, and erode structures, requiring players to engineer moats or reinforce their towers with damp sand so they can withstand incoming tides.

Tools, Exploration, and Upgrades

To construct their coastal fortresses, players are provided with a variety of tools designed to mold sand, build up towers, carve battlements, and shape moats. Beyond building, players can decorate their creations using items scattered around the shore, including pebbles, driftwood, shells, and seaweed.

Rock Paper Shotgun described the game as a way to enjoy the fun of the beach without facing real-world drawbacks like sunburns, crowded shores, or lingering sand. Exploration plays a direct role in progression through a hidden-object collection system. By finding shells and starfishes on the beach, players can unlock new customization features. These unlocks include different sand types as well as alternative beach layouts, such as lagoons, deltas, and sand barriers.

Demo and Release Details

Sandcastle is currently in development for PC, with support planned across Windows, macOS, and SteamOS/Linux on Steam. Although the developer has not yet announced a full release date, a playable demo is scheduled to launch on August 6, 2026.
