Blockhaven Sandbox — an honest story about a game that owns your evening

Sometimes the simplest-looking game hooks you harder than a blockbuster. This is exactly that case: the rules take a minute to learn, and putting it down is much harder.

What this game is

Blockhaven (Кубомир) is a voxel sandbox: an endless 3D world made of blocks that you can dig, build and explore right on the page, no install. Creative mode hands you a kit of materials (stone, planks, torches, glass, a diamond pickaxe), and the world is generated from a random seed — hills, forests, oceans and biomes are different every time.

How to play, in short

Controls (keyboard and mouse):

• WASD to walk, Space to jump, Shift to sneak
• Double-tap W to sprint, double-tap Space in creative mode to fly
• Move the mouse to look, left click to break a block, right click to place one
• 1–9 / mouse wheel pick a hotbar item, E for inventory, Esc for the menu

Controls (touch screen):

• A virtual thumbstick on the left to walk, drag on the right to look around
• MINE / PLACE buttons dig and build, JUMP to hop

How to play:

• Type a seed (or leave it empty for a random one) and press "Play New World"
• Break blocks and build anything — there is no win, but mined blocks are counted
• Your world is saved automatically: "Continue" returns you to your last build

A few final tips

• Check out the demo mode on the game page — the AI shows how it is played, and repeating it yourself gets much easier.
• Play in short sessions: the best results come with a warmed-up head.
