Cubely: 3D Color by Number & Voxel Art Builder

Fill a 3D model cube by cube until a grey lump turns into a fox, a rocket or a lighthouse. Then open a blank grid and build something nobody has made before.

Free to play, with optional in-app purchases. Android.

Cubely key art: a voxel fox, tree and rocket around the words Build. Create. Have fun.

Inside the game

What you can do

Color by number

Pick a color, tap every cube wearing that number, and rotate the model to reach the parts hidden round the back.

Build your own

A blank grid, mirror tools and a name field, for the models nobody has made yet.

A prompt every morning

A fresh build suggestion each day, for when you want to make something but have no idea what.

Nothing to lose

No timer, no score, no lives, and no way to put a color in the wrong place. Undo is there if you need it, and every model saves exactly where you left it.

The long version

Color by number, except the pictures are 3D.

Every model is built out of cubes. A few hundred for the small ones, a couple of thousand for the big ones. Each cube wears a number. You pick a color from the palette along the bottom, tap the cubes carrying that number, and spin the model around to reach the parts you cannot see yet. A grey lump slowly turns into a fox, or a rocket, or a lighthouse.

That is the whole game. No timer, no score, no lives, and no way to put a color in the wrong place. It scratches the same itch as a pixel art coloring book, except this one you can turn over in your hands.

The smallest model is 426 cubes and goes down in about ten minutes. The biggest is just under 2,500, and it is not a single-sitting job. Everything is graded Easy, Medium, Hard or Expert off the real cube count rather than a guess, so filtering to Easy genuinely gets you something quick. It works out at roughly a quarter of the library in each tier.

Progress saves per model, so you can leave a half-finished whale sitting there for a week and pick it back up exactly where you were.

Build your own

This is the part the app was really built for. Start from an empty grid and sculpt something cube by cube. Give it a name. Then color it in like any other model, or leave it grey and come back later. Your builds live in My Creations, right next to the ready-made ones, and they get thumbnails and progress rings the same way.

There is a new build prompt every day if you want somewhere to start. Some days you can ignore it.

Power-ups and coins

You earn coins for finishing models and for saving new builds, and there is a bonus for showing up each day.

  • Bomb clears a small cluster in one go
  • Bucket floods a whole connected region of one number, which is the one you want when you hit a big flat wall of color and your thumb starts to hurt
  • Brush is for careful work

You start with three bombs and two buckets. After that they cost 45 and 70 coins. Nothing is ever locked behind coins you cannot also reach just by tapping, because a coloring app that makes you grind is missing the point.

Put some music on, pick something small, and fill it in.
