Shiba Block Community
A cozy voxel town you can live in — and now race, fly and sail across. Walk into thirty-five buildings, meet neighbours with schedules and memories, buy and trade homes on a live shared street. Then: PAW SPEEDWAY, a kart circuit with tyre walls and a pit lane; THE HIGH SHOALS, islands in a cloud sea crossed by hang-glider on rising thermals; and the SHIBA REGATTA, buoy racing where the swell itself pushes your hull. Storms blow in off the sea — and the thunder arrives late, seconds behind its own lightning.

Tidehaven
Build a colorful town on a quiet sea. Shape homes, towers, bridges and gardens in a relaxing 3D building toy.

Wander Island
A portrait-first zen 3D eco-sandbox on a floating island above a cloud sea — a faithful standalone rebuild of the original 流浪岛 (Wander Island) that preserves its design identity: **every object is ecological, the island answers, and listening is the core verb.**

Craftstrike
Voxel arena FPS meets pocket sandbox: mine any block into your backpack and build it back as cover mid-firefight, battle across hand-made arenas or seeded terrain, or relax in a full creative world with pigs, sheep and birds.

Chaos Crucible
Chaos Crucible is a chaotic 2D falling-sand sandbox: paint 12 raw elements — lava, water, oil, gunpowder, acid, ice and more — and watch emergent reactions erupt. New: drop floppy physics ragdolls and shove them around with attacks that never do damage — grab a limb to fling it, or fire a shockwave, and gunpowder blasts throw them too. Free sandbox plus six timed trials with a cloud leaderboard.

Mirage Heat
Mirage Heat is a golden-hour, top-down open-world driving sandbox. Jack cars across a procedurally generated coastal city, run delivery jobs and getaways, smash targets, and outrun a rising wanted level — then spend your take tuning and armoring your ride at the garage. Touch-first controls, portrait and landscape, no install.
