Ocean Blast: Block Puzzle

Ocean Blast: Block Puzzle sets the familiar grid-clearing game under the sea. Blocks are ocean themed, the board is a compact 8x8, and any row or column you fill disappears. Clearing more than one line in a single placement sets off combos worth large score bonuses.

There are two modes. Classic is endless and is about beating your best score. Adventure is the longer project: 100 levels spread over five ocean worlds, with coral reefs, kelp forests and sunken ships among the settings, plus boss battles. Along the way you earn coins and can use boosters, though the developer does not say what the boosters do. You can pick Easy, Medium or Hard, and progress is saved, so a long Adventure run does not have to be finished in one sitting.

Pick a mode (Classic or Adventure) and a difficulty setting. Then drag the ocean blocks onto the 8x8 grid. A row or column that is completely filled clears, and clearing several at once triggers a combo bonus. In Classic, the target is your previous best score; in Adventure, you work through the levels and the bosses.

Combos reward clearing several lines with one placement, so where two rows or columns are close to full, look for a piece that finishes both. On an 8x8 board there are only eight cells in each line. Easy, Medium and Hard are all available if one setting feels too tight.

Block Party Blast offers a similar split between 50 levels and an endless mode, and Wood Block Journey pairs an endless run with a level mode on a 9x9 sudoku-style board.
