About Skystack
Ride the swinging crane and drop glowing blocks dead-centre to build a tower into the stars. Any overhang shears away — land perfect drops to restore width, chain combos and survive the sway.
How to play: Tap / click / Space to drop the block

Rules and strategy
How to play Skystack
Drop swinging blocks onto the tower, preserve their width, and build as high as possible.
Start playing
- Watch the suspended block swing across the top of the tower.
- Tap, click, or press Space to drop it onto the block below.
- Continue with the surviving overlap; exposed overhang is cut away after every drop.
Skystack strategy tips
- Use the crane’s repeating rhythm to release at the same center point each swing.
- After a poor drop, favor stability over speed because the new target is narrower.
- Chain perfect centers whenever possible to restore width and create scoring momentum.
Ember Flight
Guide a living ember up through the forge's chimney flues — flare to rise, drift to sink. Snag golden spark motes for bonus points while wind gusts and shifting gaps turn up the heat.
Neon Surge
Hold to climb, release to dive — thread a blazing light-trail through a collapsing neon canyon of spikes, pillars and narrowing gates. Graze obstacles for bonus sparks and outrace the ghost of your last run.
★ Featured Snake
The timeless classic — eat, grow, and don't bite your tail.
Aegis Down
Meteor shards are raining on the last six crystal domes. Detonate lingering flak bursts that chain through the swarm — ammo is scarce, shells take time to fly, and the sky only gets meaner.
