Echo Stack

Every run in Echo Stack is a race against yourself.

Tap to drop blocks onto a rising tower. Time it right and you keep the full width. Miss the edge and your tower narrows — until one bad drop ends the run. It's the classic one-tap stacking challenge, but with a twist: every time you play, you're racing a ghost of your own last attempt.

RACE YOUR OWN GHOST
Your best run is saved and replayed right alongside you, block for block, tap for tap. Watch your ghost's tower rise in real time as you try to beat it. Every new personal best becomes the ghost you race next — so the game gets harder exactly as fast as you get better.

SIMPLE TO PLAY, HARD TO PUT DOWN
One tap is all it takes. No tutorials, no complicated controls — just you, a rising tower, and a rival who plays exactly as well as you did last time.

PERFECT YOUR TIMING
Land a block dead-center for a "PERFECT" placement and satisfying feedback — sound, haptics, and a visible streak. Precision is rewarded, not just survival.

KEEP THE RUN ALIVE
Missed a block right when you were about to beat your best? Watch a quick ad for one more shot at the same height — no restarting from scratch.

TRACK YOUR PROGRESS
Your top 5 all-time runs are saved locally, so you can see your improvement over time, not just your single best score.

SHARE YOUR RUNS

Echo Stack is built for quick sessions — pick it up for two minutes or twenty, and there's always a version of "you" to try to beat.
