Color Fill 3D: paint the whole board without getting hit
Color Fill 3D is a grid-painting puzzle game in which you steer a cube across a board, leaving a colored trail behind it, and try to cover every tile while avoiding the moving blocks that end the level if they touch you. Paint does not spread from a single pass: you draw a trail, close it into an enclosed shape, and the area inside fills in. Any enemy block caught inside that shape is eliminated, and the space you have already filled is safe ground. The first level is an empty grey grid with a light-blue cube at the bottom edge and a "swipe to start" prompt; the top of the screen shows a progress bar toward level 2 and a locked Challenges mode that opens at level 30.

How to play Color Fill 3D
Each level is a blank grid and a cube. The rules are short, and the difficulty comes from obstacles and moving blocks that get in the way of your trail.
- 1
Start moving
Swipe on the board or press an arrow key (or W, A, S, D) to send the cube off in that direction.
- 2
Draw a trail
Every tile the cube passes over is colored, leaving a line behind it across the empty grid.
- 3
Close the shape
Bring the trail back to your colored area to enclose a section. The enclosed space fills with your color.
- 4
Trap the moving blocks
Moving blocks end the level if they hit you, but any block inside an area you enclose is removed. Keep going until the whole board is colored.

What sets Color Fill 3D apart
Enclose to fill
Coloring the board is about closing shapes: your trail only pays off once it completes an enclosed area, and a cut-off trail is the main risk.
Enemies you can trap
Moving blocks end your run on contact, but any of them caught inside a shape you close is eliminated.
A Challenges mode at level 30
Besides the main level track, a separate Challenges button sits on the main screen, locked until you reach level 30.
Keyboard or swipe
Arrow keys and WASD both work on a computer, and a swipe moves the cube on a touchscreen.
Tips for Color Fill 3D
- Take ground in small pieces. CrazyGames' own advice is to mark your territory slowly and only take risks when time is on your side.
- Your filled area is safe. Retreat into colored ground when a moving block gets close to your trail.
- Trap enemies one at a time. Enclosing a single moving block is safer than drawing a long loop around several of them.
- Keep the open trail short. The longer the uncolored line you are drawing, the more chances something has to cut it off.
- Route around the fixed obstacles. Boards include obstacles such as rival-colored squares, so plan loops that do not run into them.

Levels and challenges
A level is complete once the whole board is covered in your color. It ends early if a moving block collides with you. Progress runs through numbered levels — the bar at the top of the screen shows the step from level 1 to level 2 — and a Challenges mode opens at level 30. The screen also carries a shop icon and a pink button marked 5 with a gem and a video symbol; we have not verified what the shop sells, so this page does not describe it.
