Block Blast is based on a drag-and-drop system for putting blocks on an 8x8 grid. The player's purpose is to arrange the blocks into complete rows or columns, removing them from the grid and earning points. One distinguishing feature is that the game continuously gives three additional blocks with each turn. These blocks vary in shape and size, creating countless strategic situations to address.

Initially, the grid has lots of room, making organization simple. However, when space reduces, players must carefully analyze each decision to ensure that the next block has enough capacity.

The requirement for long-term strategy is one of the aspects that make Block Blast appealing. Focusing entirely on quick results is generally unsuccessful in the long run.

Instead, players must keep enough space on the grid to permit larger or more complexly organized blocks. The location of each block can have an impact on future turns.

The ability to predict and plan well in advance is the key factor that allows players to prolong the block blast game and achieve impressive results. This is what distinguishes Block Blast from many other common puzzle games.
