Here are two levels that are only meant to be theoretically possible without boosters. Both are clearly intended to force you to use boosters or gold bars.
Level 5058: Legendary, 19 moves
An older version of this level was only Super Hard and had 20 moves with fewer blockers. It was originally level 5048 before the level shuffle.
Next, here's level 5060: Legendary, 21 moves
An older version had locked licorice swirls in the checkerboard. It was Legendary and had 18 moves, but the blockers took far fewer hits to remove with color bomb combos. Originally, it was level 5054 before the shuffle.
Even with 25 extra moves + UFO, I still needed to use most of those moves.
A lot of episodes have levels that are meant to force booster and/or gold bar use, but it's not often that I encounter two of these levels so close to each other in the same episode. These particular levels also render starting boosters almost completely useless because the blockers are so thick and difficult to remove.
Remember: you are expected to stockpile boosters and gold bars. You are expected to have a resource spending budget. These two levels that I encountered tonight are just proof of that.
