25. A die has the shape of a regular tetrahedron, with the four faces having 1, 2, 3 and 4 pips.

The die is placed with 4 pips ‘face down’ in one corner of the triangular grid shown, so that the face with 4 pips precisely covers the triangle marked with 4 pips.

The die is now ‘rolled’, by rotating about an edge without slipping, so that 1 pip is face down. It is rolled again, so that 2 pips are face down, as indicated.

The rolling continues until the die rests on the shaded triangle in the opposite corner of the grid.

How many pips are now face down?
