Tri-nim

The gameboard is an equilateral triangle consisting of thirty-six smaller equilateral triangles. Each triangle has a point value from zero to six. The closer to any corner of the large triangle; the higher the value of the smaller triangle.

The first player arranges counters in piles on any of the zero point triangles. Players alternate turns moving stacks of counters with the object being to move the counters off the corners of the large triangle.
