Spiralo Shamrock (1979)

This game is played on a board of concentric rings divided into spaces. Each space has a symbol (heart, diamond, spade, or shamrock). Each player has four pieces which they enter in the outer ring and attempt to move to the center. Pieces are moved by die roll. Landing on an opposing piece sends it back to the start. When a piece lands on a symbol which is covered by a piece on a different space, this forms a "pair" and entitled the moving piece to move inwards to the next circle. If this forms another pair it may move again.
