Digital Shift is a mathematical game that allows you to learn how to add and subtract numbers in a fun and non-standard way. It is suitable for both children and adults who want to learn math while having fun. The game requires the player to have quick reaction, agility, and math skills to solve numerical puzzles and use logical thinking in the process.

The goal of the game is to receive a predetermined number on the right by adding or subtracting constantly moving digits on the left. Be careful, as even one wrong selected digit can lead to failure. The game has a certain amount of time to complete each level, and the time can be increased by a bonus in the middle column, which gives 25% more time but does not add anything to the player's number.

Each level increases the speed of moving digits and decreases the time to complete the level. The game has two modes, addition and subtraction, and a big amount of levels. The design is comfortable for playing in any lighting condition, and the dynamic music adds to the gaming experience.

Overall, Digital Shift is an excellent math trainer that is both fun and educational. It is a great way to train your brain, and it is completely free to play.
