If your scores have plateaued while your accuracy keeps improving, the problem is almost certainly what you are aiming at rather than how well you hit it.
Big drops, not steady clears
Clearing three bubbles pays a fixed, small amount. Cutting the connection that drops a cluster of twenty pays many times more. A high score is usually four or five large drops, not two hundred small clears.
Let the board fill on purpose
Large hanging clusters only exist on a busy board. Keeping the field constantly clean feels safe and caps your ceiling. Allowing controlled build-up creates the structures worth cutting.
Stack the multiplier onto the drop
The highest-value moment in a run is a large drop taken while a chain is already active. That means building the multiplier first with safe clears, then spending it on the anchor — not the other way round.
Hold the tools for that moment
A colour swap that gives you the exact bubble needed for the anchor shot is worth more than any bomb used earlier. Save resources for the shot you have been building towards.
Accept the risk
Playing for drops means the board sits closer to the ceiling than is comfortable, and some runs end early. The average still comes out ahead, which is why the approach became standard.
A simple test
Look at your last run: what percentage of your points came from your three best shots? If it is under half, you are clearing when you should be cutting.
