248 scribbles is an online puzzle game where the goal is to connect blocks with the same numbers to get bigger numbers. The game takes place on a grid where players move blocks in four directions (up, down, left, right). When two blocks with the same number are joined, they are converted into one block with the sum of their numbers. The goal of the game is to continue connecting blocks as long as there are free spaces on the grid, trying to get as many numbers as possible.
