How to play Turtle Confusion

  1. Select a challenge from the Combo Box
  2. Use blocks from the various palettes to instruct the Logo turtle to replicate the pattern.

Please refer to the Activities/TurtleArt pages for basic instructions on how to use the block interface and the details of various toolbars.

The shape challenges are loaded from the Combo Box on the Project (Palette) toolbar. When you select a shape, it will be loaded onto the canvas. When you use the Erase button, the current shape is reloaded.

The available blocks are small subset of the Turtle Block blocks: the basic turtle blocks; a reduced palette of pen and color blocks; some basic arithmetic operators; the repeat block; and the action and box blocks.

The Export palette includes save as Logo; save as image; and save as Turtle Art.
