Void Stacker
Read full descriptionHide full description
Tap. Drop. Stack. A single glowing block drifts across the void. Tap anywhere to drop it. Land it perfectly, and the tower remembers ā light pulses, the streak grows, the next block forgives you. Miss, and a sliver breaks off into the dark. The deeper you go, the colder the color: violet, cyan, then near-white starlight. ā Features ā Ā· One-tap gameplay. No tutorial needed. Ā· Real 3D physics ā fragments fall, bloom, fade Ā· Perfect-stack streaks that restore lost width Ā· A color palette that evolves with your altitude Ā· Cosmic bloom, drifting starfield, deep void gradient Ā· Subtle haptics on every drop Ā· Zero menus. Zero splash. Open and play. ā For ā The three minutes before your train. The moment before sleep. The breath between meetings. No music. No noise. No fluff. Just you, one block, and the silence between stars. How high can you reach?
Sky Stack
Read full descriptionHide full description
A slab slides across the screen. Tap to drop it. Miss the edge and the overhang gets sliced off, leaving you less to work with. How high can you go? Sky Stack is built for one-handed play: portrait mode, single-tap controls, runs from 30 seconds. Perfect for the commute. No internet needed to play. ā The world changes as you climb Speed shifts up every 20 floors. Break through the clouds at 40, fight high winds at 60, enter the aurora at 80, dodge ghost slabs at 100, and leave the atmosphere at 120. ā PERFECT is everything A perfect drop widens your slab and charges the bomb. Four in a row triggers FEVER: double coins. ā The bomb Fill the bomb meter, then detonate to reset your slab to full width. A second chance when things get thin. ā Gold blocks Rare golden slabs stack three floors at once and pay bonus coins. ā Coins and power-ups Spend coins on pre-run items: Wide Base, Magnet, Fuse. Out of luck mid-run? Pay coins to continue, but the price climbs every time. ā Crafted feel Neon night visuals, an original synth soundtrack, and haptic feedback on every drop. Separate music and sound sliders, and it never interrupts your podcast. One tap to find out how high you can go.
