Do you want to go first, and if so, what is your strategy?
Another little puzzle that I worked out for myself, despite that the answer is correct...
We'll call the players 'W' and 'L' (can you guess which one wins?) The trick is to start at the end and work backwards.
W wins if he says 50, he can say this if...
L says any number in the range 40 - 49 and will have to say one of these if...
W says 39, he can say this if...
L says any number in the range 29 - 38 and will have to say one of these if...
W says 28, he can say this if...
L says any number in the range 18 -27 and will have to say one of these if...
W says 17, he can say this if...
L says any number in the range 7 - 16 and will have to say one of these if...
W starts on 6.
So that is pretty much it W wins if he starts on 6 then simply follows the sequence 6, 17, 28, 39, 50. Another way of thinking about this is that W forces each pair of numbers to go up in 11's regardless of what L says, hence he starts on 6 which is 50 - 4x11
