The game starts with a 9×9 board with three balls chosen out of seven different colors. The player can move one ball per turn.

The goal is to remove maximum quantity of
balls by forming the lines (horizontal, vertical
or diagonal) of at least five balls of the same
color.
The goal is to remove maximum quantity of balls by forming the lines (horizontal, vertical or diagonal) of at least five balls of the same color. Lines of 5 or more balls of the same color are eliminated, adding to the score, and player gains one turn, i.e. he can move another ball. If not, three new balls are added, and the game continues until the board is full.

 

The difference between light version and original is in the player’s possibility to place a ball into any free place.

Solution of the following tasks can be helpful: Find sequence

Here is how your function will be executed:

checkio({
    'steps':[[1,1],[1,2]], #list of coordinates for last game iteration
    'colors':[1,3,5],  #list of ball (possible values is 1..9) colors 
                       #for next iteration
    'map':[[0,1, ....], .... ], #current map is array of arrays.
                                #0 - empty place, 1..9 - with ball
    'clear':[[2,3],], #array or coordunates, wich was removed from map
    'score': 50, #your current score
    'all_colors':7 # count of all possible colors. 
                         # Increase after every 200 scores.
})

Your function "checkio" must return an array of 2 arrays - coordinates of movement

[[1,2]
[3,4]] # move ball from 1,2 to 3,4
