'Think Ahead' is a game of strategy and trade off. You can only remove numbers in the one horizontal row with the yellow beam behind it, and the android/iphone can only remove numbers from the vertical column of the number you choose. Then your next horizontal row is determined by the android's choice, and so on. The game ends when there are no more possible moves. Play online withe remote players or play offline.
