Fortress Mahjong Solitaire Layout
The Fortress is built from dense blocks and defensive-looking layers. It tends to reveal progress in stages as walls and inner stacks open.
Read towers, walls and the center separately
The Fortress family combines clustered positions with a central region. A free match at a tower can be easy without helping the center. Identify which row edges and upper tiles restrict each region, then look for symbols that connect their progress.
Opening plan: open a useful breach
Compare pairs by the positions they release inside a cluster. A move that opens a wall edge can create lateral access; a move on an upper stack can remove cover. You often need both effects before an inner tile becomes free.
Avoid spending your flexible edge pairs
An exposed pair that releases nothing may serve as a reserve while you open a dense region. Before consuming it, check whether one of its copies could later match a symbol inside the center. Reserve pairs are useful only when they preserve a real continuation.
Common trap: attacking only the tallest stack
Height is only one restriction. A center tile uncovered from above can still be trapped between neighbors. Look for a route from a side as well as a route down through the layers, and compare their partner requirements.
What the catalogue does and does not imply
The base Fortress design uses corner bastions and a central citadel. Progression in Mahjong Imperial replaces the fixed arrangement with compact stage geometries. Counts and layers must be read from the current stage, not inferred from the catalogue name.
