Here is an exciting variation of Tetris for those who really love math. To set a new record and win an absolute victory, you need to make groups of paired numbers. Once the pair is found, the number will double. This will continue. As a result, extra cubes with numbers will be removed and free up space for others. The goal, as in the classic Tetris, is to prevent the well from filling up. To do this, you need speed and attentiveness. Try not to make mistakes and then a new record will not keep you waiting. Good luck!
