Publisher description for Mental4
Mental4 is an adding and subtracting game. A game is five puzzles. Their scores are added together as a game-score which is added to the score-table. Left-click two numbers. The smaller number is subtracted from the larger number and added to the smaller number. In other words, the smaller number is doubled at the expense of the larger number. You keep doing this until you get either two pairs or three of a kind. Then the score is added to the game-score and the puzzle resets. When you get three of a kind, their values are added together and the fourth number is subtracted ... At the bottom-right of the picture, you can see the SUM of the four numbers. If SUM happened to be 128 and you were fortunate enough to make four 32s, you would get a huge bonus -- your score would be multiplied by seven like this 128 x 7 = 896.
