The blocks have enough distinction that it was easy to see the board, and I was able to keep track even at a high pace of shuffling. The audience for this game likely won't stray outside of the hardcore puzzle fan but if you're looking for game to expand your puzzle library, it's worth a look. Swap Blocks doesn't reinvent the puzzle genre but does provide a satisfying daily brain exercise.
