A nearly completed board can still cause trouble in Cube Filler. You may cover most of the empty spaces and then discover that reaching the last few squares takes more thought than expected.
This 3D puzzle game from Dupyx gives you a movable cube and a collection of different board layouts. Your task is to fill every empty cube by moving through the puzzle. The rules are easy to understand, but the boards introduce new objects that change how you reach your goal.
Begin with the Easy Boards
The opening puzzles help you become familiar with moving your cube. You can use the arrow keys or W, A, S and D to guide it across the board.
Mouse controls also work. Click or drag to move the cube in the direction you want.
At first, you mainly need to look at the empty spaces and work out how to cover them. The boards become more demanding as you make progress.
More Than Ordinary Cubes
Cube Filler introduces special pieces that affect your movement.
Portals provide a way to travel between different parts of a puzzle. Boost cubes change how your cube moves, while barriers can stop you from following a direct route.
These additions create new problems to solve. A route that looks simple may become harder when an obstacle blocks the way.
You need to understand what each special piece does before deciding how to travel around the board.
Look at the Spaces You Haven’t Reached
One useful habit is to examine the entire puzzle before moving. Look for empty cubes in awkward places.
Pay attention to the location of barriers and portals. A special cube may help you reach a part of the board that seems difficult to enter.
Try different approaches to understand how the pieces work together. Sometimes changing your starting idea makes the remaining spaces easier to reach.
Take Your Time with Each Puzzle
Cube Filler doesn’t rely on racing or fighting. The challenge comes from choosing movements that help you cover the board.
The simple design makes the important objects easy to see. You can concentrate on the puzzle without dealing with unnecessary distractions.
As more elements appear, you need to think about several parts of the board at once. Completing a difficult arrangement feels satisfying because you work out the path yourself.
