The block puzzle where wood turns, glass flips, steel won’t budge and molten glass melts everything in its path.

For iPhone and Android

A Short Stack game in progress: an 8 by 8 walnut board with wood, glass, steel, ice and molten glass blocks

Five materials. Five sets of rules.

Drag pieces onto the board and fill a row or column to clear it. What each block does along the way is up to its material.

  • Wood

    Rotates

    The everyday block. Tap a piece to turn it 90° before you place it.

  • Glass

    Flips

    Tap to flip it to its mirror image. A line of all glass fuses into one pane and shatters.

  • Steel

    Static

    It can’t be turned, so plan around it. A line of all steel raises a giant shield before it falls.

  • Molten Glass

    Rotates

    Earned with big combos. Place it and its whole row and column melt away, full or not.

  • Ice

    Flips

    Unlocks after level 12. Its frost wave turns nearby blocks to ice, diagonals too.

Levels when you want a goal. Endless when you don’t.

  • Levels

    Hit each level’s goal in as few moves as you can to earn up to three stars. Milestone levels open Chests.

  • Endless Mode

    No goal and no finish line, just your best score. Unlocks at level 10.

  • Daily Challenge

    A fresh puzzle every day with its own goal. Unlocks at level 8.
