Pastel Stack

Pastel Stack is a free arcade game made with AI by @mounir67, and you can play it right here in your browser.

Pastel Stack is a soothing one-tap tower builder. A glowing pastel block slides across the top of your tower — tap at the right moment to drop it. Land it clean and the tower grows; let it hang over the edge and the overhang slices away, leaving a smaller block to balance on next time.

Nail a drop dead-center for a satisfying Perfect — chain them together to keep your tower wide and your streak climbing. Every block fades into the next shade of a soft pastel rainbow, so each tower becomes its own little candy-colored skyline.

The higher you climb, the faster the blocks slide. There's no timer and no pressure to start — just you, a calm gradient sky, and the gentle rhythm of stacking. Beat your personal best, then beat it again.

• One-tap controls, made for quick relaxing sessions
• Precise slicing physics and oh-so-satisfying Perfect drops
• A bright, minimalist pastel world that's easy on the eyes
• Local high scores that track your best towers
