Guides
To complete a level you must deliver boxes of appropriate color to the designated spots, and no boxes should remain on the field (or within the action blocks).
If you do good, and all the boxes end up at their proper places safe and sound, you will get a cheerful message that the level is complete.
If something goes wrong (for example, a box falls off the conveyor), the system will be immediately shut down, and you'll be shown a friendly error message. You may also end up with a conveyor system that runs indefinitely long without making much progress. Either way, you can stop the system at any time by hitting the "Stop" button. Once the system is stopped, you can make adjustments to your design and try again. And again...
That’s it for the game’s basic mechanics. Now you should be totally ready to try it yourself.
