Level 439 is the ninth level in Alien Adventure and the 126th firefly level in Diamond Digger Saga. To pass this level, you must wake up 8 fireflies and score at least 500 points in 25 moves or fewer.
This level is almost impossible since the target has been changed from seven to eight fireflies.
- 1st board: You have to trigger the Stone Make Blocks anyway to get to the firefly, so do this first.
- 2nd board: Release the fireflies by clearing the blocks normally, and save the Magic Orb for the next board.
- 3rd board: You need a very lucky board that allows you to pass the Stone Maker Blocks without touching them (or at least just one of them).
Now all eight fireflies need to be saved. This makes the level intense, as the last firefly is impossible to reach without nuking the whole board.
