Tap the left / right half to choose your landing lane

Spiral Sift is a finite 30-floor drop through a freshly generated two-lane tower. Tap left or right before each landing: broad violet windows are reliable, amber narrow windows build a valuable combo, and red hazard sectors end the run. Every seed guarantees a reachable safe choice while changing window positions and rotation speeds. Clear the tower in about a minute, then drop straight into a new one and chase your device best.

How to play

Rules

Land through a safe window on all 30 floors. Violet windows score normally, narrow amber windows grow a combo, and red hazard sectors end the run.

Controls

Tap the left or right half of the stage before landing to choose that lane. Arrow keys or A/D work on desktop.

Tips

Look several floors ahead. A broad window protects the run, but consecutive narrow windows multiply their bonus — switch risk level before the orb reaches the platform.

Behind the game

Spiral Sift is about choosing a landing before the tower chooses it for you. The falling orb descends through thirty rotating floors, and each floor offers a left and a right lane. A wide violet window is the dependable route. A narrow amber window is a deliberate wager: passing it pays more and continues the combo, while the red sectors around the openings end the run. The control is only a tap to choose left or right, but the tower keeps moving after the choice. That makes each decision feel less like reflex alone and more like reading a rotating map under a deadline. The useful habit is to look ahead instead of staring only at the next rim. Find the broad violet opening that can rescue a run, then notice whether the following floors line up an amber sequence worth pursuing. Consecutive amber passages are valuable because their combo compounds the reward, but a single safer violet choice can preserve a score that would otherwise disappear. Choose the lane while the orb still has time to travel; late changes turn a planned route into a panic tap. The best scores come from changing risk level at the right moment—banking a stable stretch, then taking narrow windows when their rotation and lane position give a real opening. Every tower is generated from a seed. Window positions and rotation speeds vary, yet each floor sequence includes a reachable safe choice, so a failure is never a demand for impossible timing. The fixed thirty-floor descent gives a run a clean beginning and finish, usually in about a minute, rather than an endless survival loop. Its spiraling violet, amber, and red rings make the journey feel like dropping through a mechanical observatory: patterns repeat just long enough to read, then shift before they can be memorized. A restart brings a new tower, not merely a faster version of the last one.
