2048 Giant 8x8 Grid
Play the giant 8x8 version of 2048. A complex logic puzzle with 64 tiles for extended strategy and higher scores. Autosaves progress.
HOW TO PLAY: Use Arrow Keys or WASD to move tiles. On mobile, Swipe the grid. When two tiles with the same number touch, they merge into one!
About
The 2048 8x8 Giant Grid expands the traditional parameters of the sliding block puzzle, increasing the board surface area from 16 to 64 active tiles. This variance significantly alters the probability density of the game. While the standard 4×4 grid forces aggressive merging to avoid gridlock, the 8×8 configuration allows for the accumulation of multiple high-value chains simultaneously.
This tool utilizes the standard powers of two merging algorithm. When two tiles of value x collide, they merge into a single tile of value 2⋅x. The primary risk in this expanded format is not immediate space constraints, but rather segmentation - where high-value tiles become stranded in opposing quadrants, making convergence mathematically impossible without disrupting the monotonic ordering of the board.
Formulas
The scoring mechanism follows a cumulative summation. For every merge event where:
The total score S increases by the value of the new tile. The theoretical maximum value of a tile on an 8×8 grid, assuming perfect execution and 4-tile spawns, approaches:
However, practical limits are dictated by the spawn probability P(4) ≈ 0.1 and the spatial topology.
