If you see videos online showing more moves, this is the reason. The videos are outdated because the video creators make them when the levels are first released. The studio monitors all levels when they are released and they check to see how many players clear a specific level and how long it takes for them to clear it. If it's too easy or too difficult they will "tweak" the levels a bit. The video creators can't keep up with the studio changes so you are still only seeing the first video release.
I just checked on Google to see if there were any videos or tips on how to clear it with 23 moves. Nothing! Do you play any of the challenges for the rewards? Have you ever tried the Sugar Drop challenge? You can win up to 13 free boosters every 8 hours.
