The block puzzle where wood turns, steel won’t budge, glass flips and molten glass melts everything in its path.
For Android phones and tablets. iPhone and iPad coming soon.
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
RotatesThe everyday block. Tap a piece to turn it 90° before you place it.
-
Steel
StaticIt can’t be turned, so plan around it. A line of all steel raises a giant shield before it falls.
-
Glass
FlipsTap to flip it side to side, to its mirror image. A line of all glass fuses into one pane and shatters.
-
Molten Glass
RotatesIt joins at level 9, then turns up every 25 to 40 pieces, or right after you clear 3 lines at once. Its whole row and column melt away, full or not.
-
Ice
FlipsUnlocks after level 12. Tap to flip it upside down. It freezes the blocks it touches, corners too, and the blocks touching those. An empty gap stops the cold.
Made for phones and tablets.
Play on whichever you have. Short Stack has a layout made for each: compact on a phone, and spread across the whole screen on a tablet held sideways.
Phone
The board up top, and your Dock right under your thumb.
Tablet, sideways
The board in the middle, your pieces down one side, and your level, stars and next reward down the other.
Tablet, upright
The phone layout, made bigger to fill the screen.
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, and finish fast for a Speed Bonus. Every fifth level from 10 is a Hard level, and the levels never end. Close the game mid-round and it’s waiting when you come back.
-
Endless Mode
No goal and no finish line, just your best score. Play Standard, or All Rotate, where every block turns. Unlocks at level 10.
-
Daily Challenge
A fresh puzzle every day with its own goal. Clear it for a Daily Chest, and keep your streak going for a bigger Streak Chest every 7th day. Unlocks at level 8.
343 Styles to collect.

The 8 VIP Themes, with every VIP and Chest-only Style and Music Track: 193 Styles and 16 Music Tracks, including 49 animated Styles and 4 Music Tracks you’ll only find here. No Chests needed.

- Eight ready-made VIP Themes, like Deep Cosmos and Lava Forge, that put a whole animated set on in one tap

VIP Themes doesn’t remove ads. Short Stack Ultra does: it’s Lifetime and VIP Themes in one, with every Style and Music Track from the levels too, and owning Lifetime and VIP Themes counts as Ultra. Limited-time items aren’t included. Some VIP Styles move or flash; Reduce Animations in Account › Options holds them still.
