Number Click: 2048! is a tile-matching merge game. The player selects clusters of matching round-cornered, numbered square tiles to merge the pieces. Their ultimate goals are to create ever-higher numbered tiles and achieve the highest possible score. If they lose a game, they attempt to beat their previous record score.
When the player selects a single tile in a cluster, all matching adjacent tiles slide to that position and merge to create a higher-numbered tile. The tiles can slide up or down to the left, right, straight or diagonally.
A pair of matching tiles creates the sum of the identical numbers. For example, two 4 tiles create an 8 tile. With more than three tiles in a cluster, the new higher-numbered tile reflects the sum of a chain of pair merges. For example, four 8 tiles create a 32 tile because two pairs of 8 tiles create two 16 tiles that merge to form the 32 tile.
With a cluster that contains five or more tiles, the player should expect more difficulty with calculating the new tile outcome. For example, five to seven 8 tiles in a cluster form a 32 tile, while eight 8 tiles create a 64 tile. Clusters with an even number of total tiles always create matching pairs that result in higher-numbered new tiles.
Number Click: 2048! doesn't auto-merge a new tile with an adjacent identical one. The player must select the closest match to complete a separate merge. For example, if the player creates a 16 tile next to another 16 one, they must select one of the tiles to create the 32 tile.
