To obtain bigger combos then a bingo, you will need to look out for a row with only 2 shapes, covering all of the 6 columns which can make a 3x3 on itself(as marked by the 2 arrows at the bottom 5th row). From this prerequisite, you start to build your combo by looking at the top of the row and bottom of it.
Of course, this puzzle has already a sea donkey in place by changing the middle 2 pieces of that row. Usually this wouldn't be the case, so you have to manually build it first by carefully shifting the the pieces above that row to get the best puzzle you can, before starting to build the bottom.
Building the bottom is much more easier than building the top, cause when you break pieces below the row, the row wouldn't be affected. From this puzzle, you can try to build a Vegas by breaking those small pieces marked by the circles. Of course if you will only get a Vegas if you are in luck. Therefore, it will be easier if you find the prerequisite row as high up the puzzle as possible, so that you can see where is the required piece for you to get the vegas, and you can shift it accordingly.
This should be all the information you need to know to get a higher ranked Ultimate. Enjoy your bilging.
