The Stacking Trilogy is a game anthology featuring three of Dieter Stein's early signature stacking games. It includes the following three titles:
Abande - Add your piece or move them onto adjacent enemy stack while keeping all stacks connected throughout the game.
Attangle - Trap your opponent's pieces from two different directions and beneath your stacks.
Accasta Pari - Capture opponents through continuous split-move chains while aiming to occupy enemy territory.
The board features double-sided printing: one side for Abande and Attangle with a central point, and the other for Accasta Pari with the “castle” areas.
