The more ducks you remove from a level, the bigger the score. Try to create large lines of ducks. If you have the chance to remove two or three ducks to get more ducks for your next move, do so. Sometimes, removing the ducks one color at a time works well. Start with whatever color has the fewest ducks. Removing one color at a time may build large stacks of other colors. Spend time to prepare your moves. Search for patterns and areas where you can create large stacks of ducks.
