2048 (http://gabrielecirulli.github.io/2048/) is a wildly popular single-player puzzle game available on smartphones as well as the web, consisting of a 4*4 tile board, which is initially partially filled with low numbers such as 2. The objective is to slide numbered tiles on the grid to combine them and create a tile with the number 2048. The game is a variation of the sliding block puzzle where equal numbers merge to form a single tile with their sum.

The filling up of blank tiles on the board reflects building time pressure eliminating the need for a separate timer. There is no alternate end state since the game is over if the board fills up without achieving 2048. Thus, as the player progresses in the game, there is an increase in the dramatic tension of the gameplay.

The elusive 2048 tile ensures repetitive play of the game, helping interactors gain insights about which strategies can be employed to achieve the goal. 2048 includes a scoreboard and a leaderboard to ensure competition. However, the score mechanics are unclear making the score a distraction. 2048 tries to reach the sweet spot between being overly familiar and over grinding.
