Are you smart enough to solve these puzzles?
The object of this game is to end up with a board filled with only zero's. When you tap on a field the number in this field and all the neighbors (horizontal, vertical and diagonal) are decreased by one, hence the name minusOne.
The game can be played on boards of sizes 3x3, 4x4 and 5x5 and you can choose from five levels of difficulty.
Don't be fooled by the simplicity of the rules, you'll soon discover that larger boards and higher levels are real brainteasers.
