FF1(2) + FF1(2) = FF2(4)
FF2(4) + FF2(4) = FF3(8)
FF3(8) + FF3(8) = FF4(16)
...
FFX (1028) + FFX (1028) = Happy Bob (2048) and win.
If you want to practice before playing, the original makes a lot more sense. Try playing it first if you're not sure on the rules.
Pyschotic is in the lead, followed by Colonel Angus and then Bubba. Comeptions are open until the 15th, so See if anyone else can beat psychotic's score by then. I know a certain Kiwi managed to get a 5 digit score over the weekend....
