 Game with the exchange of checkers                      
 (Ancient invention of Alone Coder.)              
                                                                
Field 8x8. 12 checkers for one player, 12 for another. Arrangement   
similar to regular checkers (i.e. on 3 nearby rows), but one     
the player places his checkers on the white squares, the other - on the black squares.      
                                                                
The task is to move all your checkers to the far 3 rows. Who spent  
The first one wins.                                         
                                                                
The move is made like this: the checker moves either forward-right, or      
forward-left; if she then ended up in the “gate” between  
two enemy checkers (located vertically or along    
horizontally with a gap of one cell), then she makes another 
walk (if he can walk); if after that she turned out again 
in the “gate”, then one more move (again, if he can walk), and 
etc.                                                            
                                                                
As can be seen from the rules, the game ends no later than on the 60th 
go. The number of moves depends on the experience of the players - how     
often they give to each other"gates". However, with a cunning strategy 
opponents constantly force each other to create “gates”,   
depriving them of other moves.
