Shadow Stack

Shadow Stack is a calm, no-reflex stacking puzzle. Each level shows a dashed skyline outline over a seven-column stage, plus a small hand of irregular blocks: dominoes, triominoes, L, T, S and O shapes. Tap a piece in the tray to select it, tap again or press Rotate to turn it, then press on the stage and drag to pick a column. An amber ghost shows where the piece will land.

Pieces fall straight down and rest on your stack, and the space under an overhang is free, so a piece can bridge a low spot without filling it. Match every column to the outline to clear the level and bank bonus points for pieces you did not need. Clearing a level brings a fresh outline with one more piece to place.
