Tower Slide

Tower Slide is a one-tap 3D tower-stacking game. It runs entirely in the browser, on a desktop or a phone, from one self-contained HTML file. There are no image or audio files: the 3D is drawn by code on a plain canvas and every sound is synthesized in the browser. Development started on 11 November 2026.

How it plays

• One button. A floor slides back and forth above the tower. Tap, click or press Space to drop it. The part that overlaps the floor below stays; the overhang is sliced off and falls. Miss the tower and the run ends.
• Four sides. Floors arrive from all four sides in turn, so you have to line them up both ways, and they speed up as the tower grows.
• Perfect drops. A dead-centre drop slices nothing and leaves a golden seam. Chain three or more and the floors grow back, which is how a narrowed tower recovers.
• Golden floors. Every 10th floor is golden and pays coins, more the less of it you lose.
• Superpowers. Placed floors earn energy. Spend it to slow the sliding floor to half speed, or to call in a wrecking ball that takes back your last floor.

A city of your own

• Every tower you finish is rebuilt at full size behind the next one, until the skyline is made of your own runs. Once the city is full, only a new height record gets in, and it replaces the shortest tower.
• Open the city from the home screen to orbit it and see its total population.
• Bigger floors house more people, and perfect drops the most. Height earns the ranks, from Garden Shed to Legend.
• Daily missions and a small store, paid for with the coins you earn.
