Simple puzzle game perfect for a short break or time spent in bus or train.
Minimalistic puzzle game in which the player's goal is to fill all the fields of the board with a green color (number 5).
At the start of the game board is filled with random numbers from 1 to 9 and the corresponding colors which looks similar to a geographic physical map (colors from blue through green to red). During the game the player pressed fields on the board to increase or decrease their value. After pressing a particular field, the value in this field is increased or decreased by 2, and the values of the four directly adjacent fields are incremented or decremented by 1 (depending on the choice on the button under the board - "+" or "-"). The game ends when all fields on the board are set to number 5. During the game player's moves are counted and are visible below the board.
The player can choose from three possible board sizes. The gamestate is saved, so the game can continued after interruption.
