Pebblefen: Color Lines Puzzle

The classic colour-lines puzzle: move a pebble along an open path, line up five of a colour to clear them, and keep the fen from filling. Sixteen goal stages, an endless fen and a daily fen; shapes on every colour. Free, no ads, no tracking.

Pebblefen is the classic colour-lines puzzle in a quiet fen. Move one river pebble a turn along an open path; line up five or more of a colour and they clear. If nothing clears, three new pebbles wash in.

The run ends when the fen is full, so every move is a choice between building a line and keeping room to breathe.

• Sixteen goal stages: blue lines, long lines, twin lines, scores to reach, stones to crumble, floods to survive
• Classic endless fen where colours rise from five to seven as your score grows
• A daily fen with the same pebbles for everyone
• Moss pebbles that count as any colour and standing stones that crumble when a line clears beside them
• Shapes on every colour so pebbles read without colour vision
• Keyboard, mouse or touch, in English or Bulgarian
