In C1 (or cone), each player commands 1 cone, 4 pyramids, and 10 sliding tiles with unique movements. Players manoeuvre their pieces to eliminate opponent tiles and ultimately surround the enemy cone on all four orthogonal sides using pieces or the voids left by vanished tiles.

Inventor: Michael Seal

See Lumicube and BoardGameGeek: C1.

The C2 (two-move) option is experimental and is not listed as a standard variant here.
