Pick a ball, plan a path, and line up four of a kind. Popline is a calm color-lines puzzle about thinking two moves ahead - every move that does not clear a line drops three new balls onto the board.
HOW IT PLAYS
Tap a ball, then tap where it should go. It rolls there along free cells. Line up four or more of the same color - in a row, column or diagonal - and they pop. Miss, and three new balls join the board. Keep the board breathing.
PLAN AHEAD
The next three colors are always visible. Use them: set up double lines, keep escape lanes open, and do not let the corners silt up. One careless move can flood the board; one clever one can empty half of it.
CLEAN AND CALM
Flat, minimal look. Soft pops and a gentle marimba loop. No timers, no lives, no pressure - just you and the board.
SHORT SESSIONS, LONG GAME
A round takes a few minutes; chasing your own high score takes forever. How long can you keep the board alive?
