Merge Blocks 3D is a three-dimensional 2048 puzzle game that offers relaxing physics-style elements. The player's goal is to merge blocks until they create a block that matches the number on a flag flying on a flagpole at the center of a circular, rotating platform.
The player rolls a projectile block toward the flagpole and other blocks. When two blocks match, they merge and create the new, higher-number block automatically. If the player creates a block that matches the flag, they receive coins and an advertising-based coins multiplier. Chests filled with free coins and other treasures appear on the platform during play and every time the player levels up. They also receive bonuses for completing combination maneuvers.
Merge Blocks 3D allows the player to upgrade the theme of the blocks to include other shapes like fruits. It also supplies boosters to make gameplay better, including a megaphone that shakes the platform to roll some matching blocks into each other, a magnet that merges matching blocks no matter their positions on the platform, and a color ball that levels up any block. The player can also use a bomb to blow up a block that's in the way of their merging two blocks.
