Recognition Tips

Mirrored axes; tents can't connect to form kites.

Algorithms

Best Alg: 1,0/2,-1/-2,1/-1,-1/-3,0/0,1

Swap isolated edge on top with tent on bottom, forming opposite trees.

Color Mirror Algs

Use best alg canceled with /6,6/ at the end.

Other Algs

  • 0,-1/3,0/-2,1/-1,-1/-3,0/0,1
  • -2,0/-4,-1/-2,1/-4,-1/4,1/-1,0: Put shells on left, pair tent on bottom with edge from tent on top to form gem/spill.

Mirrors

Left/Right Mirror: When both the top and bottom face are swapped with their respective left/right mirrors.
Pseudo Mirrors: When only one face is left/right mirrored. Not a real mirror, but it looks like one; don't be tricked!
