Strategy for N = 12, 18,

 

 

 

Let's look at the game: n=6(k+1), k=1,2,3... (12,18,24,30...spots)

The first player's best chance is 1(n+1)2.

 

n+

 

1) 1(n+1)2 3(n+2)3[1,4] 1(n+3)3 n+2(n+4)n+3

 

2) 1(n+1)2 3(n+2)3[1,4] 3(n+3)n+1 n+2(n+4)n+3

 

3) 1(n+1)2 3(n+2)3[1,4] 3((n+3)@1)n+2 n+1(n+4)n+3

 

4) 1(n+1)2 3(n+2)3[1,4] 3(n+3)n+2[4] n+1(n+4)n+3

 

5) 1(n+1)2 3(n+2)3[1,4] 3(n+3)5 n+2(n+4)n+3[5]

 

6) 1(n+1)2 3(n+2)3[1,4] 5(n+3)6 3(n+4)n+2[5,7]

 

7) 1(n+1)2 3(n+2)3[1,4] 5(n+3)5 5(n+4)n+3[6,7]

 

8) 1(n+1)2 3(n+2)3[1,4] 5(n+3)5[6-m] m=6s, s=1,2,3

 

8.1) n=m

5((n+4)@3)n+3
