Fill up the factory with as much butter as you can! Each piece of butter comes in its own unique shape that you will need to place on the grid. Move your mouse to find the spot to place your butter. If you want to rotate the butter, use the Left / Right Arrow Keys to rotate it counterclockwise or clockwise, or click the arrows on the right side of the screen. Once you're ready to place your butter, click to place it. You can see how many pieces of butter need to be filled into the grid by the quota shown on the left side of the screen.

You'll see the next piece of butter to place on the right side of the screen. If you can't fit a butter cube on the grid, throw it in the trash bin on the left side of the screen. If you don't trash any pieces for the round, you'll earn bonus points!

If you fill up a row or column with butter, you'll score even more points! Once the board has been filled with as much butter as possible, the butter will be removed from the grid to be delivered. Any spaces that were not filled with butter will be placed with blocker tiles. These tiles will not allow you to place butter there. Each blocker tile has a number showing how many rounds it will stay on the board. After each round, that number will decrease by one.

As you progress, you will get "eraser" versions of butter shapes. These shapes will be translucent and can be placed on existing butter blocks to remove them from the grid and free up more space.
