I still have trouble with these tougher levels but find that if, when I first start the game, I focus on where my artifacts need to be in order to free them (ie: can't free them if they are on the ledges) I try to move them asap to the correct column early on. The problem is we click these so quickly as we know time is short; another problem is that the computer clicks for us when matches are made, sometimes interfering with the plans we tried to set up. It can be so frustrating but sometimes, like with the level with the flowers or whatever they are, you get down to the last second and only 1 flower to free and you run out of time-now that is frustrating. ladytramp
