In case you're not aware, the reds and blues are not random. The 'deck' of the game has 12 cards in it[1], 4 ones, 4 twos, and 4 threes. These are shuffled and then played one at a time. After all 12 have come out, they are shuffled again. This means you can plan for which card is to come next. Yes, you will sometimes get 4 (or more!) blues in a row, but developing strategies that allow you to survive those situations is one of the things you have to do if you want to get the 6144 tile. [1] this isn't quite accurate, as sometimes a large card is inserted into the deck, I think on average 1 every 36 cards, but I don't actually remember.
