2048 is a truly unique puzzle game that is easy to pick up but tough to master. 2048 is somewhat of a math game but don’t worry it won’t attack you with difficult math equations. The game is played on a 4 by 4 grid and operates on a simple addition gameplay loop that involves tiles with even numbers on them.

When two tiles with the same number on them collide, for example, a 2 and another 2, they will combine to form a 4. The cycle may continue up until it hits triple digits depending on how you choose to play but the overall goal is to end at one single tile. Each combination gives you points but true mastery of the game is achieved when you can complete a level with the least amount of points as it means you completed it in fewer moves.
