Haskell syntax error?

I cant compile this part of code: 

game a = let 
             gameBoard ++ a
             black = test a colors
             white = (test2 a colors) - black
             createScore black white
         in 
             merge gameBoard score

geting: Syntax error in declaration (unexpected `}', possibly due to bad layout)

Thanks for help.

The in is part of the same let statement, so has to be on the same line or further indented, for example

game a = let 
             gameBoard ++ a
             black = test a colors
             white = (test2 a colors) - black
             createScore black white
               in 
                 merge gameBoard score

Haskell's layout rule for syntax is roughly that if it's further in it's the same line, if it's lined up it's a new line within a block, and if it's outdented it's the end of a block, which is why your in generated a close brace.
