01Core mechanic
Rotate a three-dimensional tile cube and remove free matching pairs against the clock.
02How a run ends
The run usually fails when a move creates isolated gaps or removes the free space needed to rearrange later pieces.
03Opening plan
Spend the first turns reading the full board, identify the non-reversible move and preserve at least one flexible route.
04Common mistake
Do not solve only the most obvious local match; check what that move leaves behind for the following turn.
05Advanced tip
Work from protruding edges toward the center and remember newly exposed symbols so you do not spend time rotating back to the same view.
