It's a really neat variation of a puzzle game that kinda doesn't provide much of a challenge. You simply move the board in 4 different directions as the numbers continue to double as you hit them with the same number starting with 2, and going to insanely high numbers like 32,768. While there isn't much difficulty getting to higher numbers as you can literally just mash a keyboard to get to 2048, the core game could proof to be a rather neat puzzle in an adventure game where it has strict rules or perhaps a timed event. If you're looking for a dopemine rush for bigger number go up, 2048 7x7 can give that to you. If you're looking a challenge, look somewhere else.
