Merge Block 2048 is a tile-merging game that uses blocks instead of classic 2048 tiles. Unlike most cube versions, this game relies on soft-body physics. The blocks feature non-solid surfaces. One block can sink into a matching block that absorbs it like drops of liquid merging together. That said, non-matching cubes tumble or become stuck in positions like more solid, children's building blocks.
The game features four columns in a board that displays the score and highest-number block. It also autodrops blocks with speed warnings. The player must merge blocks in and across columns as fast as possible because the game spawns new blocks and drops them at two different speeds. A green warning above one of the columns indicates a normal speed. A yellow warning indicates a faster speed.
As with other 2048 games, the goal is to add matching blocks to create higher-numbered blocks until reaching the ultimate 2048 block. Additionally, this version features a hard-to-reach infinity block. It also allows the player to lift and toss blocks into matching blocks or atop non-matching ones. As a result, they can tug a block from a lower level and deposit it on a higher level to open a merge space between two matching blocks on the lower level.
If a column or the entire board fills with blocks, the game ends. The player can revive by watching an advertisement.
