Rubik's Triamid

Solve the Edges

The end is near? No, the end is here! All the edges are now in place, and chances are some may need inverting. The best plan of attack is this: Invert pairs of edges first (either adjacent or opposite); that way you only have to use the simple Pyraminx type moves, and solve two edges at the same time to boot. After the smoke clears, there may be a single edge piece left over that still needs inverting, in which case you have to use the more complicated Triamid type move.

Step I: Invert 2 Adjacent Edges

If two edges that need to be inverted are next to each other, then rotate the entire Triamid so that...

• Both edges are on the front side.
• One is at the upper-left, while the other is at the upper-right.

Set up:	Do the move...	Result:
	R+ T- R- T+ R- L+ R+ L-	Both edges pieces are solved!

However, be aware that other edges may also be inverted. If so, then either repeat this stage or...

Step II: Invert 2 Opposite Edges

If two edges that need to be inverted are away from each other, then rotate the entire Triamid so that...

• One edge is on the front side, at the bottom.
• Another edge is also on the back spine, at the middle.

Set up:	Do the move...	Result:
	R+ T+ R- T+ L- T- L+ T-	Both edges pieces are solved!

However, be aware that a single edge might be inverted. If so, then...

Step III: Invert a Single Edge

If only a single edge needs to be inverted, then rotate the entire Triamid so that the edge is on the bottom side, at the back-left (see diagram).

Set up:	Do the move...	Comments:
	Lf- Rf- Lf- Rf+ Lf- Rf- Lf- Rf+	You may have to do this move twice before the last edge piece is solved.

After the move, the last edge piece is either solved or "solid" (both sides showing the same color). If it is solid, then do the move again, and the edge (and the entire puzzle) will be solved... guaranteed!
