    This one was posted a couple of days ago and it looks like it was surfaced by HNs algorithms. Since it's now basically a duplicate, it should probably be removed or hidden.

      Sure, "only 64 bits of state" is interesting. I find it more interesting though that it is less than 190 non-obfuscated lines - and it actually works.

      Nice job.

        Whats so crazy about it though? Intuitively it seems very likely to me that all possible states of 2028 would fit into a 64 bit number.

        4x4 = 16 tiles, 64/16 = 4 bits, 16 powers of two = space for 0-65536 per tile.

        So going up to only 2048 would leave some room even.
