the move stealers blow up in 4 and 5 moves 

artifact options ... a) extra move(s) ... b) remove move stealer(s) 

425 is a challenge ... 80 bubbles in 24 moves ... that is 3.3 bubbles each turn 

general approach ... use blasters early and often ... when a blaster is not found try to create a crown with a 4-letter word 

save some crowns for the last few moves to hit any isolated bubbles 

approximate range ... 20990 2 stars ... 22000  3 stars
