Logic and math come together in Number Merging as you merge and complete levels by filling the meter at the top left. To receive a tile with a new numerical value on the playing field, it is necessary that there be three or more elements with the same number nearby. When merging, you will get one tile with a number, one more, and a tile with a positive or negative value will be added to the bottom. It is these tiles that will become the tool for producing mergers. You transfer them to the playing field where, after placing them, a merger will occur in Number Merging. If there are no tiles at the bottom and the scale is not yet full, the level will fail.
