Cubes

A real 3D world of cubes — with your monster, or online with other players.

Cubes is a living 3D world where anything can be built and anything taken apart. You don’t play it alone: your monster, the one with horns and a screen for a face, really plays along. It finds its way round obstacles, fetches what you ask for, puts up torches, stands up for you and warns you of danger. Say build a lighthouse — and the monster builds it, block by block. Online you can play with other people too: up to eight players in one world, each with a monster of their own.

Ask, and the monster brings what you need, finding its way round obstacles.

🔥 Puts up torches

Getting dark? The monster lights the place up.

🏠 Builds

A shelter for the night straight away — and, on your word, a cottage, a lighthouse or a windmill.

🛡️ Guards and warns

Spots danger, tells you in time — and stands up for you when it counts.

💬 Talks the whole way

Out loud and in the chat, right in the middle of the game.

Goals to reach, one after another — there is always something to go for.

The monster builds new · 19 builds on your word

The cosy cottage from the monster’s book of blueprints: plank walls on a stone base, a steep red roof with a chimney, windows, a path to the door, flowers and bushes by the entrance
Cosy cottagea stone base, a steep roof, a chimney and flowers by the door
A red-and-white striped lighthouse by the water: a stone base, a gallery with railings, a glass lantern and a red cap
Lighthouse22 blocks tall, with stairs up to the light
A windmill: a cobblestone base with a door, a wooden tower under a steep roof and four sails
Windmillfour sails over a stone base
Hani’s lodge on the snow: a roof down to the ground with snow on the ridge, an open entrance with a glowing moon above it, and a little yard with a gate
Hani’s lodgea moon glows over the door, like the crescent on Hani’s forehead

Say build a cottage, and the monster picks a spot nearby, turns the door towards you and builds with its own hands, block by block: the foundation, the walls, the roof — and then flowers by the porch. Where it is high, it puts up scaffolding and takes it down afterwards. On the way it tells you how it’s going: Laying the foundation!, Now the roof!, Done! Come on in!

  • By voice, in the chat or in the Builds sheet — the little house button at the top of the screen: pictures, size, material.
  • Material — to suit the place: spruce in the taiga, sandstone in the desert, snow on the snow, moon blocks on the Moon. Or name it: a bigger cottage of stone.
  • In Creative everything is at hand: a cosy cottage goes up in about three minutes.
  • In Survival the monster fells trees and digs stone, then makes planks, doors and stairs. No glass? It asks you for some and puts in wooden bars meanwhile.
  • Lend a hand — your blocks in the right places count. Stop building stops it; carry on building picks it up again, even another day.
  • Never touches other people’s builds and never walls you in.

And three quick jobs on your word, with no blueprint at all:

🌙 Build a shelter

A quick shelter around you for the night, when the night creatures come out.

📐 Flatten the ground here

Level ground around you: 11×11 — or 7×7 if you ask for a little, 17×17 if you ask for a bigger one.

⛏️ Dig us a cave

A 5×5 room with torches, dug into a hillside — or, with no hill nearby, underground, down a flight of steps.

An open world on the server: a cottage and a red-and-white lighthouse by the sea, with a monster on top of the lighthouse still building it; three players with nicknames and tags over their heads — Ola·K7Q, Петя·4F2, Tom·9XD — and their monsters beside them
A shared world: nicknames with tags overhead, and everyone’s own monster

Online play up to 8 players in a world

On the Cubes title screen, tap Online play. The list shows the open worlds: whose world it is, the mode, how many of eight are playing. Join someone else’s, start a New world on the server — or open your own: in the pause menu tap Open the world to everyone, and it moves to the server with all its builds. Bring it home in My worlds takes it back, with everything your guests have built.

  • A nickname — no account, no e-mail. Over your head: the nickname and a short tag, so namesakes don’t get mixed up — Tom·9XD.
  • Everyone has their own monster beside them: it fetches, builds and talks. The monster’s mind lives on its owner’s phone.
  • The host of a world can send a player away and close the world.
  • An open chat, for ages 13 and up. An AI on our own server checks every message before anyone sees it. Tap someone’s message to Report or Mute. Rule-breakers are muted automatically; repeat offenders get banned.
  • Your data: only what the game needs goes to the server, and Delete my data from the server is one button. The details are in the privacy policy.

The arena and Hani’s story stay in single play.

A night shelter under a cliff: a cobblestone hut with a door and a ladder, torches round it; lava falls from the rock into a pool and a spring runs beside it; the person and the monster by the hut, two mischievous night creatures at the edge of the light
The first night: torches, a hut — and someone at the edge of the light

Survival and Creative

The start menu opens right over the living world. Pick Survival — or Creative, and simply build.

  • Water and lava flow — for real.
  • Crafting in one tap: the recipes are in a book — pick one, and it’s made.
  • A workbench, a furnace, chests and buckets.
  • Health, hunger and a bed to sleep in.
  • Night creatures come out after dark. Want it calm? Pick the Peaceful difficulty.
  • Doors, ladders, torches — for a home of your own.
A village of monster-neighbours from above: a well at the crossroads, stone and wooden houses, a fenced field of carrots and wheat, a sheep pen; neighbours with screens for faces, the person and the monster by the well
The village: neighbours, fields and a well

The road to diamonds

Go down into mines and old ruins after diamonds. Villages are home to monster-neighbours: trade with them for stars and take on their quests.

And there is Hani, the white wolf: tame Hani — and ride.

  • fields and a vegetable garden
  • fishing
  • a bow and arrows
  • armour
  • maps
  • weather and thunderstorms
  • horses
  • boats
  • minecarts on rails
The arena: three islands hanging in the void among clouds — the person’s base with red wool and a red bed, the stone island in the middle with the monster on it, and the monster’s base with blue wool and a blue bed; a bridge of wool reaches out from each base
Your bed is red, the monster’s is blue

Arena

A duel on islands hanging in the void. Guard your bed — and break the monster’s.

The monster’s strength adapts to yours, so roughly half the matches end in your favour: winning is never a given, and never out of reach.

White Wolf Hani the finale

On the Moon: the person and the monster by a lit portal of moon blocks; moon hares around them, a star moth and a moon jelly in the air — and the big Earth in the black sky
The Moon: low gravity, kind folk — and the Earth in a black sky
The portal to the Moon, lit, on a meadow at dusk: a frame of moon blocks with a swirl of light inside, the person on one side and the monster on the other, a torch and flowers around

The finale is Hani’s story. A portal lit by a star leads to the Moon. Gravity is low there — every jump is long and high. Moon hares and other kind moon folk live there, and the moon house keeps the secret of Hani’s crescent.

At the very end comes a scene of the three of you together: you, your monster and Hani.

In the credits

Dad and younger daughter Leya

Hani is a white wolf drawn by Leya, the author’s daughter — with a dark crescent moon and a blue star between the eyes.

Where to find it. Cubes lives inside the My AI friend app for Android: open What shall we do? and pick it from the list of games. Online play is on the Cubes title screen; the builds are under the little house button at the top — or just ask the monster.

Coming soon to Google Play

The game is with testers now, together with the whole My AI friend app. Meanwhile, come and meet the monster.
