The Add Slots trick gives you more room on the conveyor belt by adding N extra neutral-colored slots instantly. When you activate this trick, the new slots appear on your conveyor belt with a quick animation.
Because these slots are neutral-colored, they can hold pieces of any color, giving you much-needed flexibility during a tough level!
How it Works
These extra slots are only available for your current attempt at the level.
If you restart the level, the conveyor belt will return to its original starting size.
