Drop, fit, and clear your way through a grid that keps asking for more. Ultimate Block Puzzle is a chill-but-clever logic game where you drag shaped blocks onto an open board and snap them into place to wipe full rows and columns. There's no timer breathing down your neck, just you, the grid, and that quiet hum of figuring out where each piece belongs. Every clear opens up space, and every smart placement sets up the next big chain. You can fel a streak building before it even lands, so the real question is how long can you keep the board breathing?
How to Play & Controls
- Click and drag a block from the tray onto the grid
- Release to drop it into an open spot
- Fill a complete row or column to clear it and score
- Drag a piece back to the tray to rethink your move
Tips & Tricks
- Keep the center open so larger L and square pieces always have somewhere to land.
- Line up two clears at once by filing a shared corner for a double-clear bonus.
- Watch the incoming three pieces and place the bulkiest one first to avoid geting boxed in.
