01Core mechanic
Combine matching number blocks to build larger values while keeping the board open.
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 backward from the goal and avoid moves that create isolated spaces.
