Spirals is a simple "four-in-a-row" strategy game. Players take it in turns to drop a piece into the circular board. A player wins when they have places four pieces in 'a row'. On a circular board, this means four consecutive pieces in the same ring, pie section, or in a diagonal - which looks like a spiral. Spirals Pro supports one player mode, two player mode (on the same device), multiple difficulty levels, saving up to 3 games and undoing moves.
