Congratulations! You completed Puzzle 15. (However, you could have used only 4 blocks.)

You just wrote 9 lines of code!

All-time total: 36 lines of code.

Even top universities teach block-based coding (e.g., Berkeley,Harvard). But under the hood, the blocks you have assembled can also be shown in JavaScript, the world's most widely used coding language:

while (notFinished()) {
  if (isPathForward()) {
    moveForward();
  }
  if (isPathRight()) {
    turnRight();
  }
  if (isPathForward()) {
    moveForward();
  }
  if (isPathRight()) {
    moveForward();
  }
}

puzzle 9

When a block is grey, that means you can't delete it or change it. Try and solve this puzzle using the "repeat" block that repeats 3 times. Try putting these 3 blocks inside the grey "repeat" block: move, move, turn.
