QuestHub play guide

How to play

Objective

Build an ordered sequence of available functions whose final cube pattern exactly matches the target shown above it.

Controls

Click an available function to add it to the program, or drag it into the program on the right.
Drag functions to reorder them, click a selected function to remove it, and use Reset to clear the level program.

Your first move

On level 0.1, add the function that maps yellow cubes to red cubes as the built-in help suggests.

Practical tip

When several functions are needed, compare every intermediate wall—the order of transformations changes the result.

Testing note:In Chrome, verify both click-to-add and drag-to-reorder behavior, then confirm Reset restores an empty program.
