About game
+ Minus is a game where you need to solve simple examples in your head within a given time and score points to advance to the next level.
Your goal is to reach the final, 100th level.
To complete a level, you need to score a certain number of points, which is indicated at the top left. This number will decrease with each new example solved, and when it reaches zero, you will move on to the next level. When the board is completely filled with tiles, the game will end.
With each new level, the time to fill the board will decrease, and the required number of points will increase. The value of each example corresponds to the level number.
During the game, you can make no more than two mistakes. After the third mistake, you will be offered to watch a video ad to return to the game or end the game. The option to return to the game becomes available only after level 4. After watching the ad, you will be returned two levels back.
