BlockCraft

BlockCraft is a Minecraft-style voxel sandbox right in your browser. The huge world is made of blocks, and you can break and place them however you like: dig mines, build houses and castles, bridge rivers. The world is genuinely big and varied — more than twenty biomes: oak and birch forests, cactus deserts, snowy mountains, jungles, swamps, acacia savannas and striped badlands. Ores hide underground where the deep mines get dark — glowstone comes in handy — and at night the world comes alive in its own way. The game features flowing water, TNT with chain explosions, a day-night cycle, flying and sprinting. No installation, no registration — just jump in and play for free on your phone or computer.
