Reef Connect Challenge

Reef Connect Challenge turns tile matching into something closer to tracing a current underwater. Draw a line between three or more matching blocks and they vanish, letting new tiles rise from the ocean floor to refill the board. The colours echo coral and fish, so clearing a cluster feels like sweeping a patch of reef clean rather than popping icons.

The challenge builds slowly. Early boards give plenty of matching tiles within easy reach, but later layouts pack the grid tighter, forcing you to plan a line before you commit - clear the wrong cluster first and a good match on the far side becomes unreachable. Connecting the right tiles first, not just the nearest match, keeps later levels interesting.

How to play

Look at the board before you draw anything - trace a line connecting three or more tiles of the same kind and they clear, opening space for new tiles to rise from below. Plan which cluster to clear first, since removing one group can cut off a match you needed elsewhere. Work through each board steadily rather than connecting the first match you spot.

Controls

Click and drag across matching tiles to draw a connecting line, then release to clear them. On mobile, trace the same connection with a finger.
