About this game
Make room for colorful cargo on an 8 × 8 board. Fill rows and columns, build clear streaks, and try a fresh 30-placement Daily tide alongside unlimited Free voyage.
Independent block puzzle inspired by the publicly described 8×8 placement and line-clearing rules of Block Blaster on CrazyGames. Original code, harbor artwork, scoring, daily seeds and synthesized sound by TapNest Play. Not affiliated with Block Blaster, Onki Games or CrazyGames.
How to play
Drag a cargo piece onto the board, or select it and tap its top-left square. Pieces cannot rotate. Complete rows or columns to clear them; use all three pieces to refill the rack. The run ends when none of the remaining pieces fits. Daily tide also ends after 30 placements. Keys 1–3 select pieces, arrows aim, Enter or Space places, U undoes, H suggests a legal placement, and P or Escape pauses. Undo reverses one placement for free, including after a run ends. New voyage or Retry tide asks before resetting the current run. Both mode boards, one-step undo, personal bests and sound preference save in this browser; there is no cloud sync or online leaderboard.

Start with a clear lane
In Free voyage, the bottom row begins with six filled squares. Select the horizontal pair and place its top-left block in row 8, column 7. That completes the row for 12 points: two placed blocks plus a ten-point line bonus. Daily tide starts with an empty board instead.
Clear a cross for a bigger reward
Every placed block earns one point. A line bonus adds 10 multiplied by the square of the number of lines cleared and by the current clear streak. Clearing a row and column together counts as two lines, even at their shared square. For example, a single block completing that cross on the first clear earns 41 points. A placement that clears no line resets the streak.
Plan around the whole rack
All three cargo pieces are visible and may be placed in any order. They keep their orientation and cannot overlap existing cargo. New pieces arrive only after all three are used. A dim piece cannot currently fit, but another piece may clear the space it needs. Keep a wide area available for larger shapes; new racks are not guaranteed to have a solution.
A fresh tide each UTC day
Daily tide allows up to 30 placements and uses a date-based cargo sequence. The run ends early if no remaining piece fits. Retrying the same date starts with the same sequence; changing the order of pieces changes the board. A fresh page load after midnight UTC starts the new date and resets the daily personal best. Free voyage has no move limit. Neither mode has a timer.
Undo, hints and saved voyages
Undo restores the previous board and rack, including the random seed when a refill occurred. Only one previous placement is kept. Hints suggest a legal placement with a preference for immediate clears; they do not guarantee a long-term solution. Switching modes preserves both boards. Clearing browser storage removes saved runs and personal bests; blocked storage still permits play in the open tab.
Questions about Block Harbor
Can I rotate the blocks?
No. Every piece keeps the orientation shown in the cargo rack. Place another piece first if you need to clear a space.
Is this the original Block Blaster?
No. Block Harbor is an original TapNest Play implementation of the block-placement genre, with its own art, scoring, modes and local saves. It does not embed CrazyGames or use its accounts.
