Scratch 1.0, released on May 15, 2007, was the first stable version of Scratch released to the public.[1]


As this was the first public version of Scratch, there were no previous versions to compare it to. However, it can be compared to Scratch 1.4. One notable difference is the lack of cap blocks; all cap blocks in Scratch 1.4 (besides the Forever and Forever If () blocks) were stack blocks in 1.0.

Note Note: Sounds from Scratch 1.0 projects are static when loaded with Scratch 2.0 and Scratch 3.0 when sounds are compressed because 1.0 uses a different file format than later versions.[2]

Some features include:


A total of 95 blocks in 5 shapes were in Scratch 1.0.

Blocks could be activated by double-clicking. Comments did not exist in this release.

Experimental Blocks

Main article: Experimental Blocks

Scratch versions from 1.0 to 1.2 have experimental blocks that can be accessed by shift-clicking the "extras" menu (the 1.0 equivalent of Shift-Click-R) and choosing "show experimental blocks".

The Sound palette had blocks that worked with the ScratchMoviePlayerMorph:

  • start movie
  • stop movie
  • change seconds by (1)
  • set seconds to (0)
  • change zoom by (10)
  • set zoom to (100)%
  • change horiz. pan by (10)
  • set horiz. pan to (0)
  • change vert. pan by (10)
  • set vert. pan to (0)
  • change fade by (-10)
  • set fade to (100)%
  • set fade color to []
The experimental Sensing Reporter blocks.

The Sensing palette included nine camera interaction blocks:

  • camera motion
  • camera direction
  • camera relative x
  • camera relative y
  • camera absolute x
  • camera absolute y
  • track motion
  • track color
  • auto calibrate red

None of the reporters worked properly; all of them simply showed "a ScratchSpriteMorph()". Camera support was eventually added in Scratch 2.0.


The 1.0 user interface looked remarkably similar to the 1.4 interface; however, there were some differences:

  • There was only one menu. Some features were shown as buttons, while others were lumped into the "extras" menu. There was also an icon for the project notes on the right. The extras menu contained:
    • about
    • set blocks language
    • start single stepping
    • import sprite
    • import project
    • compress sounds
    • compress images
  • The Green Flag and Stop Sign are much larger.
  • There is a button to create a new Scratch Cat (the default sprite) along with the other methods of creating a new sprite.
  • Sprite thumbnails (including the stage's) show the thumbnail, name, amount of costumes, and amount of scripts. The stage's background count only shows with two or more backgrounds.
  • No Draggable Sprite Feature.
  • Costume/sound delete button is a button instead of an "x" icon.


There are two known variants of Scratch 1.0: 1.0.1 and 1.0.2.

1.0.1 was never released; only internal builds are available. A build from January 24, 2007 can be downloaded here[dead link]. Net Scratch was based on this version.

1.0.2 was released in April 2007;[3] it is available here[dead link]. Minor changes were made in this build, such as not resetting the pen state to "up" when the stop button is clicked.
