Blokus

This puzzle was set for Scojo's weekly setting prompt, redeemed by Juggler.
I used to play blokus growing up, but I don't remember there being math involved... Enjoy!
Rules:
Normal sudoku rules apply.
Digits in a blok sum to a total, which must be deduced. Bloks of the same color have the same total. Bloks of different colors have different totals. Digits MAY repeat in bloks.
A digit in a blok must appear in all bloks of the same shape, reflections and rotations included. It may appear a different number of times, and may appear in different relative positions in the blok. Digits may appear in multiple different shapes of bloks.

Testers discovered that the graphics quickly became a visual distraction, so I used cleaner graphics and labels for colors. In case it is still appealing, the puzzle with original graphics is linked here:
Solution code: Column 2

When "A digit in a blok must appear in all bloks of the same shape, ..." is true how is it possible that the three L shaped blok's (4 cells) have three different colors and sums? Or did I miss something?
/edit: Ahhhh! Thx now I know.

Spoiler/Hint:
It is true that a digit in a blok must appear in all same-shaped bloks. It is also true that digits may repeat in bloks, so they may appear a different number of times in each, making different sums. Glad you asked! Hopefully that helps :)
