About this game

Grid Blast is a polished block puzzle for mobile browsers. Place colorful gem blocks on an 8×8 board, complete full rows and columns, and chase high scores with combo streaks.

Tips and strategy

• Read the tray before you place anything. Swapping slots is free, so the row you clear should be one your current pieces can actually finish, not one you are hoping to complete.
• Rotating a piece costs nothing, so try the other orientations before deciding a spot will not work. Most shapes that look wrong have a turn that slots in perfectly.
• Keep a lane open along the edge. Building from the middle outwards leaves you flexible space, while single gaps scattered through every row are where a run stalls.
• Chase star gems only when they fit the board you already have. A combo built from clean rows out-earns a bonus gem that leaves two dead rows behind it.

Frequently asked questions

How does scoring work in Grid Blast?

You score by completing full rows and columns. Clearing several lines at once, or clearing them on consecutive placements, builds a combo streak that raises what you earn, and special star gems add a bonus on top.

Can I rotate the blocks in Grid Blast?

Yes. Tap a block in the tray to rotate it, and you can drag between tray slots to reshuffle the order so the piece you need is easier to reach before you place it.

Can I play Grid Blast on my phone?

Yes. It is made for mobile browsers and the whole game is tapping and dragging, with the landscape canvas keeping the 8x8 grid and your tray side by side.
