Sky Stack is a calm, one-tap tower-stacking game. A block slides back and forth across the top of the screen, and a single tap drops it onto the tower below. Whatever hangs over the edge gets sliced off and tumbles away, so the cleaner your timing, the wider your tower stays. Stack to the target height to clear the level. Ten levels, each faster and taller than the last.

ONE TAP, THAT'S IT

Tap anywhere to drop the block. No virtual stick, no buttons, no fuss. You can build a whole tower one-handed on a crowded bus.

LINE IT UP

Each block starts as wide as the one below it. Drop it off-centre and the overhang is sliced away, leaving you a narrower block for next time. String together tidy drops to keep your tower fat and forgiving.

NAIL A PERFECT

Land a block dead-centre and it counts as a PERFECT -- you keep full width and your combo bonus climbs. Chain perfects for a rising score multiplier and watch the points stack as fast as the blocks.

KEEP YOUR TRIES

Miss the tower completely and you lose a try (shown as dots at the top). A few misses are fine, but run out and the tower topples -- level over, tap once to rebuild.

TEN LEVELS

Level 01 is a gentle eight-block warm-up. Level 10 is a fast, narrow skyscraper that demands nerves of steel. Block speed, tower height, starting width and the perfect window are hand-tuned for every level, so each one feels fresh. Clear a level to unlock the next; the skyline remembers your cleared levels and best scores.

THE BUILDER LOG

A dedicated stats screen tracks your building: total plays, blocks stacked, perfects landed, levels cleared, and a best-score bar for every level. Beat your own records -- the log keeps them all.

HOW TO PLAY, BUILT IN

A clean six-step illustrated guide sits one tap from the title screen. Hand the phone to anyone and they will be stacking in ten seconds.

SHORT LEVELS, CALM FUN

A level takes a minute or two. Pause any time; resume, restart, or quit from the same panel. A soft twilight palette and a rainbow tower make it a relaxing little builder for any spare moment.

PRIVACY

Sky Stack keeps everything on your device. No sign-in, no cloud, no analytics, no ad SDK. Progress lives in local storage only; uninstall the app and it is gone. The release build requests no network permission at all.
